Question

Which of the following statistical test is most suited for a continuous variable where data is collected before and after an intervention?

• A. Unpaired t-test
• B. Paired t-test
• C. Chi-square test
• D. Standard deviation

Hint:

The paired t-test is ideal for analyzing data from repeated measurements, such as pre and post-intervention studies.

Answer 1

The Correct Option is B

The paired t-test compares the means of a continuous variable from the same subjects, measured before and after an intervention. It inherently accounts for the data's dependency, as measurements originate from identical individuals.
