Quizplus · Accepted Answer

Inferential statistics relies on probability theory to make predictions and inferences about a population based on a sample. This includes calculating the likelihood of certain outcomes and determining the level of confidence in the results. Levels of significance and statistical significance are components of inferential statistics, but they alone cannot provide the basis for full inferential analysis. Multiple regression is a specific statistical technique used to analyze the relationship between multiple variables, but it is not required for all inferential statistics analyses.
