Making decisions and predictions often requires making inferences about the population in general from the limited set of data you have observed.
This process is often called inductive reasoning, which relies on the statistical process of drawing generalized conclusions based on an empirical sample.
We will explore and practice this inferential statistics process in the business context. We will explore topics such as:
