Question

A researcher asks participants to either write about a time they felt happy or write about a time they felt sad. The participant then rates their current level of happiness. The researcher finds that those who wrote about a happy memory are happier currently than those who wrote about an unhappy memory. What test should the researcher run on this data set

Answer 1

The test that is right for the researcher to run this data set is independent samples t-test

For better understanding of why the test should be run on independent samples t-test, we need to understand what the term is and when it is been used.

• An independent samples t-test  is often used by a researcher who is trying to compare two groups of scores from two entirely or oddly separate groups of people.  The data used in this type of t test is always from two separate groups (time they felt happy-happy memory and a time they felt sad-unhappy memory) and then the comparison of the difference between them is done.

• It is also called between-subjects t-test.

Conclusively, from the above, we can therefore say that the test that is right for the researcher to run this data set is independent samples t-test.
