A behavioral research situation that could use a Pearson coefficient research study and a chi square research study. Present the rationale for each selection. Be very specific in your presentation.
Pearson coefficient detects the extent to which two variables move together or are related for numerical data. That is not "cause" just co-occurrence. Like crime and ice cream sales both rise and fall together. Why? They both rise in warm weather! But crime and ice cream sales are correlated and the Pearson coefficient will measure the degree of correlation from 0 (no relationship) to 1 (maximum perfect synchronized relationship).
