4. Correlation and regression Correlation and regression are two closely related topics in statistics. For each of the following statements, indicate whether the statement is true of correlation, true of regression, true of both correlation and regression, or true of neither correlation nor regression. You can assume that regression is with one predictor variable only (often referred to as simple regression). You can also assume that correlation refers to the Pearson product-moment correlation coefficient (r). Regression Correlation Both Correlation and Regression Neither Correlation nor Regression Requires a measure for both variables' individual variances Can be tested for statistical significance Provides a way to predict a specific value of one variable (such as weight) from the value of another variable (such as height)
