Our **FEBRUARY 2022** through **JUNE 2022** contests use data from **[Olshan, Vitiello, & Ratliff (2021)][1]**
You can find the data for this study [here][2].
CONTEST: **FEBRUARY 2022**
Your tasks for the PsiChiR contest include:
Level 1: Write script that will compute the “TotalCog” mean score from the 18 Need for Cognition variables (cog1 through cog18)
Level 2: Create a frequencies table for the TotalCog variable
Level 3: Create a scatterplot of the relation between the TotalCog and IAT scores
Level 4: Run correlation between the TotalCog and IAT scores. Calculate probability value and CIs.
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).
