Data That consists of dependent variable y and two independent variables x1 and x2. Where y = height of the person in inches, x1 = weight of the person (same person) in lbs, and x2 = shoe size of the person (same person). About 8-10 persons will be sufficient, the more the better. Example:

y x1 x2

66 185 8.5

70 158 9.5

Step-1 Regress y on x1

• present your equation of regression model
• report on r 2, SSE and ANOVA table

Step-2 Regress y on x1 and x2

• present your equation of regression model
• report on r 2, SSE and ANOVA table
• describe the changes on r 2, SSE, and ANOVA table
