Expert Solution

ANSWER:

i) Comparing pain levels of a group receiving a placebo to a group receiving a medicine.

Here, we compare the pain levels of two different groups. Hence, there are two different independent samples.

Answer : Independent Samples

ii)Comparing the number of speeding tickets received by men to the number received by women

Here, there are two independent samples, men and women.

Answer : Independent Samples

iii)Comparing pain levels before and after treatment with magnetic therapy

Here, we compare the pain levels of the same patient before and after treatment. Therefore, the samples are dependent.

Answer : Matched Pairs

iv)Comparing pre-test scores before training to post-test scores.

Here, we compare the scores of the same individual before and after training.

Answer : Matched Pairs
