### Description

Introduction to Statistics in Psychology is a comprehensive, modern guide to understanding and using statistics in psychological research. This edition has been significantly revised to incorporate the essential SPSS steps you need for carrying out statistical analysis.

### Contents

1. Why statistics? Part 1: Descriptive statistics 2. Some basics: Variability and measurement 3. Describing variables: Tables and diagrams 4. Describing variables numerically: Averages, variation and spread 5. Shapes of Distributions of Scores 6. Standard deviation and z-scores: The standard unit of measurement in statistics 7. Relationships between two or more variables: Diagrams and tables 8. Correlation coefficients: Pearson correlation and Spearman's rho 9. Regression: Prediction with precision Part 2: Significance testing 10. Samples and populations: Generalising and inferring 11. Statistical significance for the correlation coefficient: A practical introduction to statistical inference 12. Standard error: The standard deviation of the means of samples 13. The t-test: Comparing two samples of correlated/related scores 14. The t-test: Comparing two samples of unrelated/uncorrelated scores 15. Chi-square: Differences between samples of frequency data 16. Probability 17. Reporting significance levels succinctly 18. One-tailed versus two-tailed significance testing 19. Ranking tests: Nonparametric statistics Part 3: Introduction to analysis of variance 20. The variance ratio test: The F-ratio to compare two variances 21. Analysis of variance (ANOVA): Introduction to the one-way unrelated or uncorrelated ANOVA 22. Analysis of variance for correlated scores or repeated measures 23. Two-way analysis of variance for unrelated/uncorrelated scores: Two studies for the price of one? 24. Multiple comparisons in ANOVA: Just where do the differences lie? 25.
