Identify the correlation coefficient for each of the possible pairings of variables. Describe the relationship in terms of strength (weak/strong) and direction (positive/negative).

Find a linear model of the relationship between the three variables of interest. Identify the predictor variables and the criterion variable.

Provide an output of the SPSS results and interpret the results using correct APA style. Be sure to include the following in your interpretation:

• Cause and effect concepts
• Independent/dependent variable relationships?
• Why is important to do random sampling?
• What is regression fallacy? How may it apply to the relationships discovered?
