A retail analyst is trying to understand what drives total monthly spending by customers. She finds that: The correlation between income and spending is r = 0.45 The correlation between loyalty program membership (1 = member, 0 = non-member) and spending is r = 0.50 She then runs a multiple regression with spending as the dependent variable and includes income and loyalty program membership as independent variables. Surprisingly, income becomes statistically insignificant, while loyalty program membership remains significant. Which of the following best explains why income was significant in the correlation analysis but not in the regression?
