a. Dependent Variable: Runoff
A geomorphologist is building a model to understand variation in the amount of
runoff observed in various streams within a large drainage basin. Linear regression is
used to determine whether runoff is inversely related to the porosity of the soil. The
variables here are thus runoff and porosity. The SPSS output from the analysis is
shown above. One of the cases has a runoff value of 900 and a porosity value of 8.
Calculate the value of the residual for this case.
