Introduction:

The main idea of a multiple regression analysis is to understand the relationship between several independent variables and a single dependent variable. (Lind, 2004) A model of the relationship is hypothesized, and estimates of the parameter values are used to develop an estimated regression equation.(abyss.uoregon.edu) The multiple regression equation used to describe the relationship is: Y' = a + b1X1 + b2X2 + b3X3 +……. + bkXk. It is used to estimate Y given selected X values and k independent variables. (Lind, 2004)
There are two components of a multiple regression analysis that are important; the coefficient of correlation (multiple R) and coefficient of determination (R²). The coefficient of correlation is the degree to which two or more independent variables are related to the dependent variable. The coefficient of determination is "the proportion of the total variation in the dependent variable that is explained by the independent variable. It can assume......
