What is a residual for a multiple regression model and the data that is used to create it? Select one. A statistic that is used to evaluate the significance of the multiple regression model A statistic that explains the relationship between response and predictor variables The predicted value of the response variable using the multiple regression model The difference between the actual value of the response variable and the corresponding predicted value (regression error) using the multiple regression model

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…
