How to Calculate Variance – Definition, Formula, and Calculation

The variance is widely used in statistics and mathematics. In statistics, this term is frequently used to calculate the spread of the data from the expected value. It measures the typical distance of the data values in the same units such as meter squares.

There is another term that is more stable to measure the spread of data is the standard deviation. It has the unit’s time and meter. In this lesson, we will discuss the variance in descriptive statistics along with its definition, formula, and calculations.

Variance – introduction

In descriptive statistics, a term that is the average of the squared deviation (square of the difference of the data values from the expected value) from the mean is known as the variance. It is widely used to measure the variability in the distribution of data values.

It is expressed in larger units such as m2 (square meters or meter squares). It is generally used to represent how much variation in the data set there from the expected value. The zero value of the variance indicates that all the values are identical in the data set.

It is denoted by “σ2” or “s2” and is calculated by subtracting the expected value from the data value and taking the square of the deviation and dividing it by the total number of observations.

Types of variance

Variance used two kinds of data sets one is a sample and the other is a population, on the basis of these sets the variance has two types

Population variance & sample variance

In this section, we will discuss the types of variance briefly.

1.  Population variance

Population variance is that type of variance in which the population data set is taken. The population is the measure of all the data such as people in a city or girls in a country. Hence the measure of the spread of the whole data set from the expected value indicates the population variance.

For the calculation of population variance, you have to calculate the quotient of the statistical sum of squares and the total number of data values. It is denoted by “σ2”. The measure of the expected value in population variance is denoted by “μ”.

2.  Sample variance

Sample variance is that type of variance in which the sample (random) data set is taken. The sample is the measure of random data from the whole such as people in a school in a city or girls in a class of a high school. Hence the measure of the spread of sample (random) data set from the expected value indicates the sample variance.

For the calculation of sample variance, you have to calculate the quotient of the statistical sum of squares and the total number of data values minus one. It is denoted by “s2”. The measure of the expected value in sample variance is denoted by “”.

Formulas of the variance

The formula for the population variance is:

σ2 = ∑ (yi – μ)2/N

The formula for the sample variance is:

s2 = ∑ (yiȳ)2/N -1

In the above formulas of the variance,

  • σ2 and s2 are the notations of population and sample variances respectively.
  • Yi is the set of the data values.
  • N is the total number data value.
  • μ & ȳ are the populations mean and sample means respectively.
  • ∑ (yi – μ)2 & ∑ (yi – ȳ)2 are the statistical sum of squares.

A variance calculator can be used to solve the variance problems according to the above formulas of variance.

How to calculate the variance?

Let us take some examples to understand how to calculate the variance.

Example 1: For population variance

Evaluate the population variance if the given data set is:

10, 15, 20, 22, 25, 28


Step 1: First of all, calculate the population means of the given data set.

Sum of population values = 10 + 15 + 20 + 22 + 25 + 28

Sum of population values = 120

Total number of observation = n = 6

Mean of population data set = μ = 120/20 = 60/10 = 30/5

Mean of population data set = μ = 6

Step 2: Now value the deviation of the data values from the population mean.

y1 – μ = 10 – 20 = -10

y2 – μ = 15 – 20 = -5

y3 – μ = 20 – 20 = 0

y4 – μ = 22 – 20 = 2

y5 – μ = 25 – 20 = 5

y6 – μ = 28 – 20 = 8

Step 3: Now make the above differences by taking the square of each term.

(y1 – μ)2 = (-10)2 = 100

(y2 – μ)2 = (-5)2 = 25

(y3 – μ)2 = (0)2 = 0

(y4 – μ)2 = (2)2 = 4

(y5 – μ)2 = (5)2 = 25

(y6 – μ)2 = (8)2 = 64

Step 4: Now calculate the statistical sum of squares by adding all the above-squared deviations.

∑ (yi – μ)2 = 100 + 25 + 0 + 4 + 25 + 64

∑ (yi – μ)2 = 218

Step 5: Take the quotient of the ∑ (yi – μ)2 (sum of squares) and the total number of observations to calculate the population variance of the given data set.

∑ (yi – μ)2 / N = 218 / 6 = 109/3

∑ (yi – μ)2 / N = 36.33

Example 2: For sample variance

Evaluate the sample variance of the given set of observations.

1, 3, 8, 12, 21


Step 1: First of all, calculate the sample mean of the given data set.

Sum of sample values = 1 + 3 + 8 + 12 + 21

Sum of sample values = 45

Total number of observation = n = 5

Sample mean of data set = ȳ = 45/5

Sample mean of data set = ȳ = 9

Step 2: Now value the deviation of the data values from the sample mean.

y1 – ȳ = 1 – 9 = -8

y2 – ȳ = 3 – 9 = -6

y3 – ȳ = 8 – 9 = -1

y4 – ȳ = 12 – 9 = 3

y5 – ȳ = 20 – 9 = 11

Step 3: Now make the above differences by taking the square of each term.

(y1 – ȳ)2 = (-9)2 = 81

(y2 – ȳ)2 = (-6)2 = 36

(y3 – ȳ)2 = (-1)2 = 1

(y4 – ȳ)2 = (3)2 = 9

(y5 – ȳ)2 = (11)2 = 121

Step 4: Now calculate the statistical sum of squares by adding all the above-squared deviations.

∑ (yi – ȳ)2 = 81 + 36 + 1 + 9 + 121

∑ (yi – ȳ)2 = 254

Step 5: Take the quotient of the ∑ (yi – ȳ)2 (sum of squares) and the total number of observations minus 1 to calculate the sample variance of the given data set.

∑ (yi – ȳ)2 / N – 1 = 254 / 5 – 1

∑ (yi – ȳ)2 / N – 1 = 254 / 4 = 127/2

∑ (yi – ȳ)2 / N – 1 = 63.5

Wrap up

In this lesson, we have learned all the basic intent of the variance with the help of solved examples. Now you can grab all the basics of the variance and able to calculate any problem of variance by following the above formulas and solved examples.


6 Benefits of Distance Learning

6 Benefits of Distance Learning

Distance learning allows you to register into an institution and complete a course without attending physical classes. You attend classes through your phone, laptop, and other gadgets. Learning will also involve a lot of e-materials like books, videos, audio presentations, and live streaming.

Distance learning is a breakaway from the traditional learning method. You do not see your teacher or have classmates in the same room. The approach to learning has shed off many elements that defined studying in the traditional sense. Is the method any beneficial to the student or will learners end up as losers?

Here is a look at the benefits of distance learning.

1. Cheaper

Education is extremely expensive. Beyond paying hefty fees, you have to abandon your business or job to attend classes. Distance learning has eliminated most of the costs related to traditional physical learning. You can get a java assignment help online without your professor noticing.

Since students do not utilize physical campuses, institutions have reduced the fees charged. It makes education an affordable event for the most prestigious universities and institutions around the world. Consequently, it has made education more accessible to students at all levels.

The cost of learning is also brought down by the fact that you do not abandon your economic activities to attend class. You can keep your job or still run your business while attending class. Students with families do not have to abandon them in search of learning opportunities.

Relocating to another city is also expensive. You have to sell your property or maintain two houses in different locations yet you are not utilizing them optimally. Distance learning allows you to study from the comfort of your home without relocating and bearing the heavy cost of living in another location.

2. Access to prestigious universities and courses

Physical campuses restricted access to a quality education because universities or colleges would only admit students based on their physical capacity. It made courses in these universities extremely competitive and out of reach for many students.

Distance learning has opened universities and colleges to more people. You can enroll in the most prestigious university or college while living in another continent. You can also take several courses in different institutions at the same time as long as you can balance the study hours effectively. Distance learning helps you to achieve your career goals easily.

3. Freedom to pursue other dreams

College years also offer opportunities to pursue other dreams. You may start a business, take up a job, or utilize your talent in sports and art. Physical learning confines you to a particular location where the pursuit of such dreams might curtail. Distance learning is the secret to pursuing other dreams while still studying.

Distance learning allows you to follow classes from the comfort of your room after work or upon the completion of a tournament. Such opportunities expand your potential and career prospects. It is a perfect step towards self-actualization.

4. Offers flexibility

Distance learning comes with flexible learning hours. With recorded classes, you can study in the evening after work or early morning before heading out. In case you miss a class, you can still catch it when done with responsibilities or engagements.

A flexible schedule helps you to attend to other issues. For instance, you can be with family during important events without worrying about missing classes. The flexibility increases your potential, especially helping you to do more with your time.

5. A critical lesson on self-motivation and management

Successful distance learning requires a lot of self-motivation and management. You must manage your time to avoid skipping classes because you are not on campus. You also have to create the right study space to complete your work. With no physical incentives to put you in line during studies, it is upon you to make distance learning work.

The time management and self-motivation skills learned will transform your life henceforth. They are crucial in your professional life. They boost your potential because you can do more without supervision.

6. Self-paced

Distance learning happens at your pace. The institution will indicate the hours you have to clock in before graduation. With the materials available, you can speed up your learning or slow down based on your engagements at each moment. It is a perfect way to avoid pressure when studying.

Distance learning has opened more opportunities for learners. It has made pursuing the desired courses cheaper and more efficient. It is also a ticket to freedom through a flexible schedule and self-paced learning. If you need to pursue other interests like business, sports, or art, you should embrace distance learning.

10 Exam Stress Tips for Students and Parents

How to deal with exam stress?

Exams are a challenging part of education for every student. There are often high marking criteria, and it seems impossible to cover them. To pass exams successfully, students should revise the material of the whole term. They should remember the material in detail and be ready to write their own creative ideas. At the same time, there are a lot of other assignments at the end of a term. You may need to do writing assignments like essays or course papers as a student. Buying essays online can be a solution to this problem. So, how do you manage your time and cope with exam stress?

Do not demand too much

This is a tip both for parents and students. Sometimes, students can suffer much stress because they want to be perfect. Remember that you do not need to have the maximum mark to pass your exam. What you need is to have enough knowledge for a good mark. There is no need to set high goals and then be frustrated. Parents should also encourage their children to have a rest. They should recommend students not to study much. This means that a student should balance studies and free time. Even at the most challenging times, you should not suffer tremendous pressure.

Make a plan

To pass your exams successfully, it is essential to have a plan. You should arrange your tasks and exams in several days. Even if you have a week left, you will manage to prepare. You can set each job on each day. You will not learn the material perfectly, yet you will get a general understanding. This will help you pass your exams with a good mark. Parents should leave their children time for preparation. They should not ask them to help with household work or distract them with conversations.

Be ready for the best

Stress often results from wrong expectations. You may imagine complex exam tasks and how you will not pass them. To relieve your stress, think about the best situation. Try to be confident that you will get a good mark and pass next year. Parents should also support their children. Your child should understand that there is no need for the best mark. It will be great if they get a sufficient mark.

Keep your working space clean

When studying, it is important to arrange the objects on your table. You should have a clean working space to find each object easily. Arrange your copybooks and manuals based on your subjects. When the time comes, you will find the necessary material quickly. If you do not have time for a clean-up, ask your parents to help you. They can do some household work themselves to give you more time.

Do some exercise

Physical activity can help your mind relax. You will get more energy to prepare for your exams and think better. When you are tired from thinking and learning, do some simple exercise. You may move your body or just go around the room. If you have enough time, take a short walk outside. Take a shower to refresh your body and mind.

Read a book

Reading your favorite books may be of great help to relax. Remember that you should not read scientific literature or your textbooks. Instead, read a simple but exciting book that will make you forget about exams. This can be a 10-minute reading, but it will help you cope with stress. Reading is also helpful an hour before your exams. When you revise the material and start writing the exams soon, you may be confused.

Have a good sleep

Sleeping is a great way to let your brain relax. You may study for a long time, but the information gets arranged in your mind when you sleep. When you get up, you remember the material better and think better. You will also feel relaxed and not have much stress. For parents, it is important to organize a good sleep for their child. For example, you may close the room and not make much noise.

Use music when you are studying

Listening to your favorite music is helpful to concentrate. You will not feel so tired and stressed if you listen to the songs you like while studying. It is also an excellent way to relax when doing a writing assignment. In addition, you may listen to music when you are going to your examination room.

Address an online writing service

A safe way to have time for your exams is to leave written assignments to a custom writing service. For example, you may purchase your course paper in DoMyEssay. The online writing service will provide you with a unique paper in time. This means that you will have more time to prepare for your tests. Furthermore, the paper will bring you the highest mark, so you will not worry about your exams. In addition, you can raise your general mark with the course paper.

Ask a tutor or parents for help

If you get stuck with a complicated theory, ask your teacher for help. You may order a tutor who will explain the information to you. Some tutors make students ready for exams. Sometimes, your parents can help you. They will explain the material and solve the problems with you.

How to Help Your Child to Cope with Exam Stress?

Exams are a challenging period in a child’s life. As a parent, you should understand this and help your children. It is important not to put your child under pressure. Do not distract them or ask them to do some household work. If your child does not understand the material, help them with the studies. Some children can’t concentrate when you are next to them. Let them stay alone or ask a tutor to help your child. Make sure your child has enough rest between their studies.

  • deadline (ASAP and not instant)
  • volume (from 1 to over 30 pages)

The longest period is one month. It suits orders that require more than thirty pages. There are eight other available due dates that a person can choose even for a one-page assignment. 4, 8, 24, 48, 72, 120, 168, and 336 hours are at your disposal. The cheapest papers are for school children. The most expensive ones are for university students.

Moreover, a person can pay less if asking for the longest deadline. A website has a free calculator that helps a person learn the final cost of the assistance. There is also a section for paper instructions. It is necessary to be precise when writing details about the order. Customers need to mention their working emails as well. Helpers will use them to send ready papers.

Are There Any Bonuses and Discounts on the Website?

The company makes prices affordable for everyone. Unfortunately, it does not have a bonus and discount policy for newcomers and regular customers. Though, the service has free options and coupons for clients who have become loyal customers. For example, a person who has already ordered and paid for 30-page homework can receive a message about free pages for the next order.

Except for no-cost pages, a person can enjoy cost-free editing, revision, and report about plagiarism scans. A customer has the right to demand a paper revision and editing if it has mistakes or does not correspond to demands mentioned in the order form. The goal of the company is to get more loyal customers. It will be impossible if papers are of low quality or doers refuse to review and edit them.

Is the Company’s Personnel Professional?

Scam websites hire people who might be amateurs and know nothing about formatting. Fortunately, AssignMaths has nothing to do with that. The company tries to hire only the best helpers. It has strict requirements for every employee. A helper needs to have a scientific degree, experience, and perform several trial tasks. So each “do my math assignment” is done on a top-level.

The company has been helping students with their Maths homework for 10 years already. Its rating is 8.5/10. It means that most reviews and comments are positive. There are over 300 professional assistants who can be in the “available”, “top-rated” or “advanced” category regarding their merits. Together, they major in 70 disciplines related to STEM subjects.

What Services Does the Company Offer to Me?

Experts on AssignMaths have done many labs, reports, presentations, capstone projects, dissertations, term papers, case studies, coursework, essays, outlines, calculations, and research papers in various STEM disciplines. Students often order papers in Engineering, Algebra, Geometry, Trigonometry, Calculus, Precalculus, Topology, Statistics, Applied Maths, Physics, Probability, and Logic.

Students can select a doer. The price depends on the status of the helper. Top-rated specialists perform ASAP tasks and volume papers before the deadline and without mistakes. As a rule, the company dedicates extra fees for their assistance, though customers are warned about that.

The service is transparent. It does not have taxes that a person has to pay to get the paper. As soon as customers pay someone to do my math homework, a performer proceeds to the task performance and does not demand a single extra penny.

Another advantage of the service is the security it offers to clients. When a person orders assistance, it will be necessary to contact banks to confirm payment. Besides, a person mentions the name and email to get the order online. Each employee signs a confidentiality agreement before getting a job. According to the document, they do not have the right to share a client’s personal information with others.

Moreover, the website runs on a secure platform that protects each payment and stored information. So, one can be sure that there will not be any data leakage.

Speaking about the quality of homework, it is important to mention that all papers are unique. Professionals never plagiarize. They discuss details with a customer and supply the paper with original information. They scan papers via plagiarism detectors and send print screens to clients. If clients want to change something, performers review and edit papers for free.

The success of the order depends on three main factors – a performer, order form details, and respect. AssignMaths is a reputable performer. If customers mention all details in the order form, its helpers will follow them. They respect every customer. That is why all clients are satisfied with the successful assistance.


Meet the Best Career Options for JavaScript Learners

Description: JavaScript is one of the popular fields that college students choose to deal with. In this article, we focus on the 10 best career options available for JavaScript students.

10 Career Opportunities for JavaScript Students

The 21st century is the time of technology. Nowadays, you will not surprise anyone with a mobile phone or free internet in public places. However, few people know how sites and applications are developed. One of the ways to develop is dynamic programming languages. Today we will talk about them in this article.

Java Programming Language

Java is an object-oriented programming language created in the 1990s by a small group of Sun Microsystems engineers, later acquired by Oracle in the 2010s. Today Java is found in many devices that are used in everyday life. In an object-oriented language like Java, we are dealing with classes and objects. A class is a blueprint for something in real life, and an object is an example of such a plan. This language has long been the most popular programming language. In the past, Java was widely used to write “applets” —small applications that ran right in the browser. For example, a calendar, guestbook, or online chat. Java is also widely used in e-commerce and web applications. In fact, Java is used everywhere: on your phone, on your set-top box, on your credit card, on the server you are currently connected to, in the browser you are currently using. Java is the most widely used language, so it’s worth learning. Java is open source and supported by many libraries, including the Java Machine Learning Library. As the name suggests, it is not only suitable for machine learning algorithms, but also for projects that use robotic systems, sensors, NLP, and neural networks.

JavaScript Programming Language

JavaScript is a full-fledged dynamic programming language that is applied to an HTML document and can provide dynamic interactivity on websites. JavaScript is commonly used as an embedded language for programmatically accessing application objects. Java applications are less error-prone and generally more functional than those built using JavaScript. But it also comes at a price, the main one being the time and complexity of development. Therefore, it is better to use JavaScript for the web, and it is better to leave the development of complex software to Java.

Main JavaScript Features

Some of the main features of JS include:

  • Dynamic typing – the data type is determined at the time of assigning a value to a constant or variable.
  • Interpreted language – application code is interpreted when accessed, no pre-compilation is required.
  • Support for prototype and object-oriented approach.
  • Versatility – All popular browsers support JavaScript.

Why JavaScript?

Here we will analyze why students should choose this particular programming language and what are its advantages.

JavaScript, despite its many flaws, is arguably the best programming language for aspiring developers, and the best language kids can tinker with. It is simple enough, but it contains all the fundamental things: algorithms, object-oriented models, data structures.

JavaScript’s incredible ubiquity is its main advantage, and one of the unique advantages of JavaScript is its ubiquity. This language can be found literally everywhere. It is supported on all operating systems, in all kinds of browsers, both on desktop computers and on mobile devices. It is also very important that JavaScript applications work without installing them on users’ computers. In fact, it’s hard to remember the not-too-old days when companies deploying client-server applications on their internal networks spent weeks struggling with configuration issues and unexpected errors. Faced with such nightmares, you may well appreciate the appeal of JavaScript.

JavaScript is the best friend of HTML and CSS. HTML defines the layout of the site, CSS is responsible for the appearance, and JavaScript brings it all to life. Using JavaScript code, the programmer determines how the page will react to user actions.

Career Opportunities for Students

As a Developer

You can write any web application using JS. And this significantly increases the demand for programmers who speak this language. And if you look at domestic sites with vacancies, there are currently more job offers for JavaScript developers than for those who program in Java or 1C. You can even find a job for a beginner specialist, and even more so for an experienced one. The Javascript programmer’s work is always well paid.

As a UI Designer

In the IT industry, there are many areas related to design. The most common of these are designers hidden behind the acronym UI. The goal of a UI designer is an aesthetically pleasing modern product design.

As a Website specialist

If the title has the word “author” then the action is structured. Planning and updating of how the site looks and functions. Moreover, the activity is clearly centered around the Internet. Additionally, decision configuration devices, HTML, CSS, and lightweight JavaScript can be explicit capabilities.

As a Frontend developer

Frontend development works through the application of the public part, which is directly related to the user, and functionality, which is usually performed on the client’s side.

As a Backend developer

A web developer is a broader concept than a front-end developer. The first designation only says that the person sees the client of the site, the second specifies what exactly – the side that the person sees the client of the site.

As a Fullstack developer

This is a developer who must understand the entire stack of technologies and parts in a component project, both in front-ends and back-ends.

As an Android developer

An Android developer is engaged in the creation, updating, improvement of mobile applications and software for smartphones, tablets, e-books, game consoles, and other devices running on the Android system.

As an iOS developer

iOS developers are among the most sought-after and highly paid professionals. They generate and implement their ideas for Apple mobile devices.

As a UX designer

UX design is responsible for the function, the adaptability of the product, and the emotions it evokes in the users. The clearer the interface, the easier it is for the user to get the result and take the targeted action.

As a web application developer

Intuitive site page enhancement. Ideal for including a JavaScript framework like jQuery, which extends your JavaScript to simplify that JavaScript.

Today, JavaScript is a one-of-a-kind language that works in all browsers – Yandex, Google Chrome, Safari, compatible with all modern operating systems, any mobile platforms, etc. If you plan to connect your future life with programming the client side of the site, or at least layout, you need to understand that without the ability to work with JavaScript, there is nothing to do there. The demand for programmers is growing, employers provide high salaries, especially for experienced professionals. These are some of the benefits that JavaScript certification offers you. Organizations need qualified JavaScript Office professionals to improve efficiency and grow their business. Becoming a JavaScript Office professional brings various benefits such as faster career growth, better pay, better job opportunities, and technology transitions. uCertify offers a comprehensive javascript specialist. Also, if you are teaching JavaScript in a college or institute, you can ask for help. There are companies that are engaged in JavaScript assignment help and are always happy to help you.
