We have now learned about (a) samples that represent their populations and (b) simple probability. Inference is a conclusion reached on the basis of evidence and reasoning. The next step is to combine these ideas. Inferential statistics (a.k.a. Null Hypothesis Testing) use probability to determine whether a particular sample (or test outcome) is truly representative of a population from which the sample was originally drawn.
This video teaches the following concepts and techniques:
