Can you use at test for more than 2 groups?
A t-test should not be used to measure differences among more than two groups, because the error structure for a t-test will underestimate the actual error when many groups are being compared.
Can a value be in multiple groups tableau?
Grouping works like a hiearchy in Tableau. So it is not possible to have 1 item in multiple groups.
What is group comparison in statistics?
A comparison between groups of individuals, usually on the basis of a representative value (such as a mean) from each.
How do you compare two groups with multiple measurements?
Out of them to identify statistically significance in measurements between 2 or more groups, it is best to use ANOVA (Analysis of Variance). You arrange the data in a two way table for each group. There will be 2 two way table, one for Group A and the other for or Group B. The go for analysis of variance.
