The textbook was developed over several years and has been used in courses offered by many California community colleges in regular and honors-level classroom settings and in distance learning classes. This textbook is intended for introductory statistics courses being taken by students at two– and four–year colleges who are majoring in fields other than math or engineering. Intermediate algebra is the only prerequisite. The book focuses on applications of statistical knowledge rather than the theory behind it. The labs have been modified to include information on mini-tabs by Mary Teegarden. [Collapse Summary]

It has been modified from the original module m17077, Facts About the Correlation Coefficient for Linear Regression, which is part of Collaborative Statistics collection (col10522) by Barbara Illowsky and Susan Dean. The test of significance is presented as a hypothesis test both using the p-value and using a table of critical values. Some of the material from the original module m17077 has been moved to module m33269 in Bloom's custom collection of Collaborative Statistics. [Collapse Summary]
