One-Way ANCOVA
The One-Way ANCOVA is a test used to determine if 3+ groups are different from each other on your variable of interest in the presence of a covariate.

Factorial ANOVA
The Factorial ANOVA is a test used to determine if two or more sets of groups are significantly different from each other on your variable of interest.

Split Plot ANOVA
The Split Plot ANOVA is a statistical test used to determine if 2 or more repeated measures from 2 or more groups are significantly different from each other on your variable of interest.

Friedman Test
The Friedman Test is a test used to determine if 3 or more measurements from the same group are different from each other on a skewed variable of interest.

Kruskal-Wallis One-Way ANOVA
The Kruskal-Wallis One-Way ANOVA is a test used to determine if 3+ groups are different from each other on a skewed variable of interest.

One-Way Repeated Measures ANOVA
One-Way Repeated Measures ANOVA is a test used to determine if 3+ related groups are significantly different from each other on a variable of interest.

One-Way ANOVA
The One-Way ANOVA is a statistical test used to determine if 3 or more groups are significantly different from each other on a variable of interest.

Mann-Whitney U Test
The Mann-Whitney U Test compares two different groups on your variable of interest (dependent variable) when your variable of interest is skewed.

Single Sample Wilcoxon Signed-Rank Test
The Single Sample Wilcoxon Signed-Rank Test is a statistical test used to see if a single group is significantly different from a known population value.

Wilcoxon Signed-Rank Test
The Wilcoxon Signed-Rank Test is a test used to determine if 2 continuous measurements from a single group are significantly different from each other.

Independent Samples Z-Test
An independent samples z-test is used to determine if 2 groups are significantly different from each other on your variable of interest.

Paired Samples T-Test
The paired samples t-test is a statistical test used to determine if two observations from the same group are significantly different from each other.
