商品簡介
Gravetter and Wallnau (both: The College at Brockport, State University of New York) have updated the previous edition published in 2010, refining content and supplementary material. Introductory chapters address the basics of descriptive statistics (frequency distributions, central tendency, and variability). Subsequent coverage includes the foundations of inferential statistics (scores and standardized distributions, probability, the distribution of sample means, and hypothesis testing); using t statistics for inferences about population means and mean differences; analysis of variance; and correlations and nonparametric tests. Appended are statistical tables, solutions for odd-numbered problems in the text, general instructions for using SPSS, and hypothesis tests for ordinal data (Mann-Whitney, Wilcoxon, Kruskal-Wallis, and Friedman tests).
