Web9.5 Inference for Regression. The previous sections in this chapter have focused on linear regression as a tool for summarizing trends in data and making predictions. These numerical summaries are analogous to the methods discussed in Chapter 2 for displaying and summarizing data. Regression is also used to make inferences about a population. WebDescriptive statistics describes data (for example, a chart or graph) and inferential statistics allows you to make predictions (“inferences”) from that data.
