Attributes types in data mining

In this tutorial, we will try to learn the followings;

  1. What is Attribute?
  2. Types Of attributes

What is Attribute?

The attribute is the property of the object. The attribute represents different features of the object. 

Example of attribute:

In this example, RollNo, Name, and Result are attributes of the object named as a student.

RollNoNameResult
1AliPass
2AkramFail

Types Of attributes

  • Binary
  • Nominal
  • Numeric
    • Interval-scaled
    • Ratio-scaled

Nominal data with example:

Nominal data is in alphabetical form and not in an integer.

Example:

AttributeValue
Categorical dataLecturer, Assistant Professor, Professor
StatesNew, Pending, Working, Complete, Finish
ColorsBlack, Brown, White, Red

Binary data with example:

Binary data have only two values/states.

Example:

AttributeValue
HIV detectedYes, No
ResultPass, Fail

The binary attribute is of two types;

  1. Symmetric binary
  2. Asymmetric binary

Symmetric data with example:

Both values are  equally important

Example:

AttributeValue
GenderMale, Female

Asymmetric data with example:

Both values are  not equally important

Example:

AttributeValue
HIV detectedYes, No
ResultPass, Fail

 

Ordinal data:

All Values have a meaningful order. 

Example:

AttributeValue
GradeA, B, C, D, F
BPS- Basic pay scale16, 17, 18

 

Discrete Data with example:

Discrete data have finite value. It can be in numerical form and can also be  in categorical form.

Example:

AttributeValue
ProfessionTeacher, Bussiness Man, Peon etc
Postal Code42200, 42300 etc

Continuous data with example:

Continuous data technically have an infinite number of steps.

Continuous data is in float type. There can be many numbers in between 1 and 2

Example:

AttributeValue
Height5.4…, 6.5….. etc
Weight50.09….  etc
