1. A psychologist wants to predict individual's scores on a depression survey using their scores on a locus of control test.
2. What is your predictor (X) variable?

1. What is your criterion (Y) variable?

2. After collecting data for both variables, the psychologist finds the following:

• COV_xy: 7.33
• Variance_x: 20.33
• Mean of X: 15.50
• Mean of Y: 17.50

3. Calculate b (slope) and a (intercept):

4. Write the regression equation:

5. Interpret the intercept and slope:

6. What would the psychologist predict an individual's depression score would be if they scored an 18 on the locus of control scale?
