You used multiple linear regression analysis to predict community reintegration (Reintegration to Normal Living Index RNLI; interval scale) from depression (Geriatric Depression Scale or GDS; interval scale) and balance (Berg balance scale; interval scale) in a sample of 200 individuals with stroke. The results are as follows:

Linear Regression Linear regression is used to predict the value of one variable from another variable. Since it is based on correlation, it cannot provide causation. In addition, the strength of the relationship between the two variables affects the ability to predict one variable from the other variable; that is, the stronger the relationship between the two variables, the better the ability to do prediction. What is one instance where you think linear regression would be useful to you in...
