We covered Ch. 11-3 Contingency Tables (Frequency counts of categorical data, test of independence, expected frequency, observed frequency, test of homogeneity), 12-1 Analysis of Variance (ANOVA, F-distribution, not symmetric, values greater than or equal to zero, shape depends on degrees of freedom), 12-2 One-Way ANOVA (Test the equality of three or more population means by analyzing sample variances, F-distribution, avoids Type I Errors), 12-3 Two-Way ANOVA (Interaction between two variables, one changes the other), 13-1 Non-Parametric Statistics (Parametric tests, e.g. parameters, normal distribution not required, can be based on a parameter, less rigid requirements, more data types, qualitative, not as efficient, rank criterion, sign test, e.g. positive and negative signs assigned), 13-2 Sign Test, 13-3 Wilcoxson Signed-Ranks Test for Matched Pairs (Non-parametric test using ranks), 13-4 Wilcoxson Rank-Sum Test for Two Independent Samples.
