Inferential statistics is a branch of statistics that makes inferences or predictions about a population based on a sample. In inferential statistics, we use models, formulas, and other varied methods to make estimates, predictions, and generalizations about a population. Using these methods, we can estimate population parameters, find confidence intervals, conduct hypothesis tests, and compare samples.
