ANOVA shows if the means of several groups are all equal, generalizes Student's 2-sample t-test to more than 2 groups http://bit.ly/17ELj0

Factorial ANOVA is used when the experimenter wants to study the effects of two or more treatment variables http://bit.ly/17ELj0

In mixed-design ANOVA, one factor is a between-subjects variable and the other is within-subjects variable http://bit.ly/17ELj0

A mixed model is a statistical model containing both fixed effects and random effects. http://bit.ly/uvAQ8

Restricted maximum likelihood is a method for fitting linear mixed models http://bit.ly/3V9wn

Wilcoxon signed-rank test is a non-parametric test for 2 related samples or repeated measurements on a single sample http://bit.ly/4EXqZU

Wilcoxon signed-rank test can be used as alternative to paired Student's t-test when population cannot be assumed to be normally distributed. Mann-Whitney-Wilcoxon is a variant of Wilcoxon signed-rank test for 2 independent samples http://bit.ly/CnATg
