B) F
C) The p-value
D) Phi

Question

Quizplus · Accepted Answer

The coefficient of determination (R^2) is the square of the Pearson correlation coefficient (r), indicating the proportion of the variance in the dependent variable that is predictable from the independent variable. Similarly, Phi (Φ) is a measure of association for two binary variables and can be derived from the chi-square statistic, making it analogous to how R^2 relates to r.
