In 2018, I collected data on how each student felt before class on Monday, and on Friday, across several weeks. A student is the independent unit, with the difference from beginning to end of the week being replicate measurements. For each week, I calculated the difference in feeling from Monday to Friday for each student. Then I averaged this across the weeks for each student (which you'll recall reduce measurement error). Migrate these data set into SPSS and test the null hypothesis that student energy on Mondays is no different than on Fridays. Please post your results and conclusion along with steps.
