This text is designed for undergraduate courses in statistics or tests and measurements in physical education. It covers basic statistical concepts such as frequency distributions; graphs and curves; percentiles; measure of central tendency and variability; correlations; t tests; special applications of t tests for unequal, small, or correlated groups; Chi square; and simple analysis of variance. Included are both parametric and nonparametric applications of these concepts. Throughout the book, examples and situations are taken from physical education data and solutions to the problems are presented as would be found in the secondary school setting. Formulas are presented and explained for the typical student majoring in physical education. Theoretical discussions are kept to a minimum. One chapter presents a review of mathematical applications of the four basic functions, square roots, and algebraic equations. Comments are made about the use of electronic calculators and how they can assist the student of statistics. The final chapter on the application of statistical tools to typical secondary school teaching situations offers assistance for improving evaluation in grading techniques and shows how problems common to the secondary school teacher can be solved by using correlations and mean difference methods. A discussion of validity, reliability, and objectivity as they relate to standardized and teacher-made tests is also included. Appendixes include statistical tables and answers to problems. (MM)
