Q1:   Mark the following as True or False.   Do not reproduce the question.  Only write True or False against the part number in your answer books.

  1. The Correlation Coefficient establishes a cause-and-effect relationship between two variables.
  2. While formulating a hypothesis, we put the desired state as the alternative.
  3. Standard Normal distribution is a bell-shaped curve symmetric about a horizontal axis.
  4. Mode represents the frequency rather than magnitude.
  5. For a sample size of 5, it is possible to have the sample average between the largest and the second Largent observation.
  6. The blood pressure reading of a patient is an example of continuous data.
  7. Cross-sectional research is a type of observational study that spreads over long time periods.
  8. The sample mean is not directly related to the sample size while the sample variance is always expected to reduce with sample size.
  9. The width of a confidence interval increases if we increase the sample size.
  10. When we study the behaviour of mice in a laboratory, it is a controlled experiment.
  11. Continuous variables can be handled through Likert scale.
  12. If each observation in a sample has a value greater than 5, the sample standard deviation cannot be more than 15.
  13. ,  is a two-sided hypothesis.
  14. Variance, standard deviation and range are measures of central location.

Q2:      List and briefly discuss the biases in Survey Research.

Q3:      What is Analysis of Variance and which distribution plays a key role in the use of results of ANOVA.

Q4:   The following table provides data on a number of students who passed/failed a specific test.

  1. Construct a hypothesis to analyze the performance of Girls compared to Boys.
  2. Compute the chi-square statistic using the tabulated data.
  3. What do we conclude from this high value of chi-square statistic?
  4. State how many degrees of freedom do we have here for this chi-square test?
