Document Summary
Comparison of means, signal to noise ratio. Does not require homogeneity, but requires sphericity. 2 qualitative ivs in the same model, predicting 1 quantitative dv. Main effect = effect of a single iv on the dv. Omnibus effect combined effect of all ivs and interactions on the dv. Factorial anova where 1+ iv is randomized group and 1+ iv is repeated- measures. Ivs of interest qualitative but now include 1 + quant control variables called covariates. Assumes homogeneity of regression (slope of the relationship between each covariate and the dv is similar in each level of the quant. Compares mean score on 1 variable in 1 population with a number. Compares mean of different scores on a variable with zero. Compares mean on 1 variable in 2 groups. Tells you strength and direction of linear relationship between two quantitative variables. Nonparametric alternative to single sample t test. Descriptive statistic = mean rank of each group.
