Our OCTOBER 2021 through JANUARY 2022 contests use data from [Goyette & Spencer (2021)][1]. https://osf.io/v4yhu/ contains information about the study. https://osf.io/9chb7/ contains an SPSS (.sav) file, that can be imported into R using the "foreign" package. [Here are instructions on doing this][2]. CONTEST: **December** **2021** Your tasks for the PsiChiR contest include: Level 1: Using “Year,” put freshmen and sophomores into one group and juniors/seniors into another group Level 2: Determine frequencies for this new variable – how many participants are in each new group Level 3: Visually compare these two groups on means for HCTotal Level 4: Statistically compare these two groups on means for HCTotal ______________________ In order to complete each level, you need to complete all levels before (so in order to complete level 4, you also need to do 1, 2, and 3 correctly).
