A clear and accessible statistics text— now fully updated and revised
Now with a new chapter showing students how to apply the right test in the right way to yield the most accurate and true result, Explaining Psychological Statistics, Fourth Edition offers students an engaging introduction to the field. Presenting the material in a logically flowing, non-intimidating way, this comprehensive text covers both introductory and advanced topics in statistics, from the basic concepts (and limitations) of null hypothesis testing to mixed-design ANOVA and multiple regression.
The Fourth Edition covers:
- Basic statistical procedures
- Frequency tables, graphs, and distributions
- Measures of central tendency and variability
- One- and two-sample hypothesis tests
- Hypothesis testing
- Interval estimation and the t distribution
