Programmed Text in Statistics Book 3: The t-Test and Chi-Squared Goodness of Fit

Hine and Wetherill - Personal Name;

Programmed Text in Statistics Book 3: The t-Test and Chi-Squared Goodness of Fit is a structured instructional textbook designed for self-paced learning in introductory inferential statistics. The book focuses on two fundamental hypothesis testing procedures: the t-test and the chi-squared (χ²) goodness-of-fit test. It explains how the t-test is used to compare sample means and assess statistical significance when population variance is unknown. It also introduces the chi-squared test as a method for evaluating how well observed data fit an expected distribution. The programmed learning format guides students step by step through definitions, calculations, and interpretation of results, reinforcing understanding through exercises and immediate feedback. The book is intended for students in mathematics, economics, business, and social sciences who require a practical foundation in statistical hypothesis testing.
