Bring into SPSS the Residual-HETERO.dat data. Each case has two scores, X and Y. The delimiter is a blank space. Conduct a regression analysis predicting Y from X. Create residuals plots and save the standardized residuals as we have been doing with each analysis. As you can see, the residuals plot shows clear evidence of heteroscedasticity.

21. What should a residual plot look like? Caution: Once you do a linear regression, there is a set of residuals that are stored automatically in the list resid on your calculator. It gets replaced if you run a linear regression on another set of data. You cannot save the residual list.

Use Stat > Regression > Regression to find the regression equation AND make a residual plot of the residuals versus the explanatory variable. To make the residual plot, use “Graphs” and then type in the name of the explanatory variable. At home: Read Chapter 5 and work the problems at the end of each short section as you go through them.

The regression equation is Weight = 123 - 5.57 Day Interpretation: the line intersects y axis at 123 with a slope of -5.57. that is on the day=0, weight is 123gm and for each increase in a day, the weight of the soap decreases on the average by 5.57 grams.
