The following section answers the questions that were asked in the analysis sheet.

The standardized slope informs that for each standard-deviation unit of increase within SES, we predict slightly many than a halves of a standard deviation increase within math score. (Tofallis, 2008)

Last, the list provides the t challenges for the slope and intercept. In multiple regression we shall get specified challenges for each predictor. The list does not tell the df for the t. We need towards know that the df for each t is the equivalent as the df for residuals within the F list above. Here the df is n-2. Each analyses the hypothesis H0: b = 0 for the predictor used.

In the above table, the sig. value of the constant and growth are less than 0.05; therefore, it implies that growth and constant have significant impact upon the voting behavior. On the other hand, inflation does not have statistical significant impact on the voting behavior as the sig. value of the variable is greater than 0.05. Based on the analysis, we can conclude that economic activities have a significant impact on the voting behavior of residents.

 

Assumptions of Multiple Linear Regression

Last we audit our assumptions. In regression we earn assumptions approximately the structural portion of the model, that is, approximately the predictor(s) and blunder term. We assume that everybody of the meaningful predictors are within our model, and none insignificant ones are included. A proper insight approximately the assumptions are granted below.

Therefore we study residual plot. These residuals don't glance very customary - it is necessarily that else predictors could explain many variation within the data. According towards the figure beneath, the data is confidently skewed and does not appear symmetry. Therefore, we are within the grading towards ...
