Question

3. In the Lindseth et al., 2014 study What inferential statistical technique was calculated to examine differences in the participants when they received the high-aspartame diet intervention versus the low-aspartame diet? Is this technique appropriate for the study? Provide rationale for your answer.

Answer 1

3) The inferential statistical technique which was calculated to examine differences in the participants of Lindseth et al study is "paired or dependent samples t - test" .

Yes, this technique is appropriate for the study.

It is because, the paired or dependent samples t-test is the statistical procedure calculated to determine differences between two sets of repeated measures data from one group of people. In this process, each subject is measured twice to get pairs of observations. Here in Lindseth et al study, healthy adults consuming high aspartame diet for 8 days and low aspartame diet for other 8 days with a 2 week gap between the consumption of two types of diets were examined for within - subject differences in mood, headache, depression, and cognition resulting in different pairs of observations.
