Video (18:29) from Research by Design in which, “Using a dataset about puppy training, we learn how to set up and run an independent samples t test. We import data into JASP, conduct the test, interpret the results and write up the findings. We will learn to check the assumptions of homogeneity of variance using a Levene’s test and normality using a Shapiro Wilk test. Finally, we learn about the comparative power of a t test, and Cohen’s d effect size, based on your research design. You should watch both this video and How to do a Paired Samples t Test in JASP (11-11) to fully understand these two tests.”
