Answer: Paired samples (dependent or related) t-test
>> The paired sample t-test or the dependent sample t-test, is a statistical procedure used to determine whether there is a difference between two sets of observations. In the paired sample t-test, each subject or entity is measured twice, resulting in pairs of observations.

-It would not be appropriate to use the Mann–Whitney U test when: a researcher is comparing two independent populations. the dependent variable is measured at the ordinal level. the assumptions for an independent-samples t test are not met. a researcher is comparing three or more groups on a normally distributed dependent variable. -Kia assesses people's levels of gratitude and stress that occur naturally to determine if a relationship exists between the two variables. Kia is using a(n): correlational design experimental...
