### Dependent and Independent Variables

Dissertation defense power point 1. Multiple regression was used to explore the relationship and predictive ability of two variables (School System and Pre Personal Involvement) Content analysis was performed to organize data for further explanation. Multiple linear regression requires at least two independent variables, which can be nominal, ordinal, or interval/ratio level variables. A rule of thumb for the sample size is that regression analysis requires at least 20 cases per independent variable in the analysis. Learn more about sample size here. Multiple Linear Regression Assumptions. The multiple regression model with all four predictors produced R², F(4, ) = , p regression weights, indicating students with higher scores on these scales were expected to have higher 1st year GPA, after controlling for the other.

### Assumptions

Regression analysis is a quantitative research method which is used when the study involves modelling and analysing several variables, where the relationship includes a dependent variable and one or more independent variables.

### Introduction

The multiple regression model with all four predictors produced R², F(4, ) = , p regression weights, indicating students with higher scores on these scales were expected to have higher 1st year GPA, after controlling for the other. Regression analysis of variance table page 18 Here is the layout of the analysis of variance table associated with Multiple regression: We have new predictors, call them (x1)new, (x2)new, (x3)new, , (xK)new. The predicted (or fitted) value for the corresponding Y value is. the results from this regression analysis could provide a precise answer to what would happen to sales if prices were to increase by 5% and promotional activit ies were to increase by 10%.
