Tests Flashcards
interval - 2 groups - independent data - parametric –>
student t or analysis of variance if only one dependent variable (ANOVA) or MANOVA if 2 DP
Student’s t test is used to compare the means between two groups, whereas ANOVA is used to compare the means among three or more groups.
interval - 2 groups - independent data - parametric –>
paired t test
repeated measures of ANOVA
repeated measures of MANOVA
interval - 2 groups - independent data - non parametric –>
Mann-whitney test
Rather than doing calculations with the distribution of data points, it calculates on the ranks of the numbers.
“Is there a significant difference between samples in group A versus the samples in group B?” when these samples do not follow a Gaussian distribution
Compares nonparametric data between two unpaired groups.
It is the nonparametric counterpart to the “unpaired t test”
interval - 2 groups - related data - non parametric –>
Wilcoxon Signed Rank
interval - 3 or more groups - independent data - parametric –>
ANOVA OR MANOVA
interval - 3 or more groups - independent data - nonparametric –>
