How to Conduct a Paired Samples t Test in JASP

In this video, you'll learn how to use JASP to conduct a paired samples t test. This corresponds with Chapter 5 of our textbook Applied Data Analysis in Psychology: Exploring Diversity with Statistics; however, you do not need to have the textbook to follow along with this walk-through.

Check can also check out my FREE companion open education resource here, it includes a paired samples t test data set and a walk-through guide with step-by-step instructions for conducting a Paired Samples t test in JASP. It also includes information about how to write up study results in APA format. scholar.utc.edu/open-textbook...

Thanks for the video! What test would you then run to see if there was a difference between the Stress_T1 and Stress_T2 for only Condition 1 or only Condition 2?

If you wanted to test time 1 and time 2 differences, you would still run a paired samples t test, you would just need to run it more than once filtering out the condition you are not interested in. For example, we filtered out the control condition at the 10:53 mark in the video. If you wanted to analyze the control condition instead, you could click to make the control condition a check mark and the denial condition an x. You just have to watch when doing that in JASP. If you did that after running your analyses for the denial condition, it would automatically update all of your output/results to the control condition instead. That means you want to copy your results for the denial condition from JASP and paste them in a separate Word document before filtering the denial condition out to analyze the control condition instead.
Alternately, let's say you wanted to analyze all the data at once - the denial and control conditions, as well as stress in time 1 and time 2. That would be a mixed repeated measures ANOVA. Stress time 1 and time 2 would be put in your repeated measures cells (your within subject factor). Condition would be your between subject factor.
