Section 7.13 Checklist
When running correlations, have you:
-
Checked which variables are numeric and suitable for correlation
-
Graphed your variables using scatterplots to visualize relationships
-
Confirmed the relationships appear linear?
-
Addressed any missing values or extreme outliers
-
Selected the appropriate type of correlation (Pearson, Spearman, or Point-Biserial)
-
Ran correlation analyses and interpreted both the direction and strength of r
-
Created a correlation matrix if working with multiple variables
-
Computed R² values to describe shared variance when appropriate
-
Ran a partial correlation if controlling for a third variable was relevant
