Written for criminal justice students, this text focuses on statistical concepts commonly used in criminal justice research and provides criminological examples to demonstrate the calculation of basic statistics.
When studying statistics, it is important to remember that concepts build upon each other and accumulate. Basic descriptive statistics derive information which serves as a shorthand or summary to describe the distribution of data. The normal curve can be used as a basic measuring device to compare scores taken from a particular study or report. Pie charts, bar graphs, and frequency polygons are major types of graphs for depicting the distribution of data. The text covers probability and sampling, hypothesis testing, the t-distribution and t-test, correlation and simple regression, analysis of variance, and chi-square and measures of association. Each chapter in the text contains a discussion and statistical presentation of the particular topic and exercises. Reference tables and an index are included. 10 references, 2 tables, 10 figures.
