Schaum's Outline of Statistics
This Schaum's Study Guide is the perfect tool for getting a handle on statistics. Fully stocked with solved problems—508 of them—it shows you how to work problems that may not have been fully explained in class. Plus you get 694 additional problems to use for practice, with answers at the back of the book. Ideal for independent study, brushup before exams, or preparation for professional tests, this Schaum's guide is clear, complete, and well-organized. It even prepares you for computer solutions of statistical problems, fully explaining the use of Minitab, the most popular statistical software. It's the perfect supplement for any course in statistics, and a super helper for the math-challenged.

Page 4 - ... x is called the independent variable, and y is called the dependent variable. The symbol /(*), which is read "/of x," is often used instead of y to represent the range value of the function.
Page 59 - An average is a value that is typical, or representative, of a set of data. Since such typical values tend to lie centrally within a set of data arranged according to magnitude, averages are also called measures of central tendency.
