Student’s t-Distribution

Investigate the normal-to-chi-square ratio behind Student’s distribution. Move from its history and shape to studentization, critical-value tables, moment existence, scale changes and simulation diagnostics.

Prerequisites: Normal and chi-square sampling distributions, sample standard deviation and probability tables. Includes single-select and multiselect practice with worked explanations and misconception analysis. Questions are independently answerable; local learning order progresses from foundations to analytical challenges.
