indicate if it involves: a) independent samples, or b) paired samples

1. Do men and women have different GPAs

Independent Samples                 Paired Samples

2. Do senior student

Solution

a) Independent samples are used when the testing does not involving pairing of observations from the 2 samples. The objective of the test is to compare 2 groups irrespective of any pairing between samples.

b) Paired samples are used when the testing is based on pairing of observations from 2 samples. Such a test aims to observe the difference in observations within pairs of data.

So based on these concepts:
