Print this file and highlight important sections and make handwritten notes as you review the results. This opens the dialogue box to specify the model. This test computes a t value for the data that is then related to a p-value for the determination of significance. As with regular regression, as you learn to use this statistical procedure and interpret its results, it is critically important to keep in mind that regression procedures rely on a number of basic assumptions about the data you are analyzing. For example, regressing average income on years of education and years of experience may produce an R-square of 0.36, which indicates that 36 percent of the variation in average incomes can be explained by variability in a person's education and experience.

The descriptive statistics will give you the values of the means and standard deviations of the variables in your regression model. Height is a linear effect in the sample model provided above while the slope is constant. A low p-value of less than .05 allows you to reject the null hypothesis. In statistics, regression analysis is a technique that can be used to analyze the relationship between predictor variables and a response variable. This analysis helps in performing the hypothesis testing for a study. He has written numerous SPSS courses and trained thousands of users.
