Question

Explain how to compare data in two different situations for the same participants.

Answer 1

Here to compare data in two different situations for the same participants.

So if we take measures on two different situations on the same participant is a dependent sample.

to compare the dependent sample we use a dependent sample t-test.

Using the repeated measures t-test (also known as the dependent measures t-test) because it is usually used to compare two related groups on the same dependent variable (such as the same people at two points in time or people in two different experimental conditions).

In a dependent sample t-test first, we take the difference between the scores of two different situations.

then find the mean & standard deviation of the score of differences.

Then do hypothesis testing for mean difference in score is statistically significant or not.

Answer:- Repeated measures t-test (dependent measures t-test or paired t-test)
