This "quick start" guide shows you how to carry out linear regression using SPSS Statistics, as well as interpret and report the results from this test. If you have two or more independent variables, rather than just one, you need to use multiple regression. For example, you could use linear regression to understand whether exam performance can be predicted based on revision time whether cigarette consumption can be predicted based on smoking duration and so forth. The variable we are using to predict the other variable's value is called the independent variable (or sometimes, the predictor variable). The variable we want to predict is called the dependent variable (or sometimes, the outcome variable). It is used when we want to predict the value of a variable based on the value of another variable. Linear regression is the next step up after correlation.
