Correlation and Regression Correlation and linear regression: Not the same, but are related Linear regression: line that best predicts Y from X Correlation: quantifies how X and Y vary together
Correlation and Regression Use correlation when both X and Y are measured Use linear regression when one of the variables is controlled

Correlation and Regression Linear regression If two variables are linearly related it is possible to develop a simple equation to predict one variable from the other The outcome variable (dependent variable) is designated the Y variable, and the predictor variable (independent variable) is designated the X variable
Correlation and Regression Assumptions • Values of the independent variable (X) are fixed and/or measured without error • For each observed value of X, there is a normally distributed population of Y values. • Variances of populations of Y values lie on a straight line • Errors in Y are additive • All values of Y are independents of all other values of Y
