Document Summary

Measures means between 2 groups, t ratio and t table, df are found using (n-1) Measures difference in means of one group measured twice, T ratio and t tables, df of usually given. More than 2 groups, measures within and between groups, uses f ratio and f table , df are found with a numerator of (groups: and the denominator is found (number of people- groups) Compares relationships, numerator is 1 , denominator is n-1 or the residual, r ratio and r table. The strength of a relationship, to use table we use number of participants and p value. =to 0 no correlation use table to find df (#of colums-1) x (#of rows-1), frequency, bigger samples, Non parametric like independent t test, measures the ranks are higher in one group over another. Ordinal paired t test, compares changes in ranks between groups. Rr! no that"s not rest and relaxation more like reasonable rage.
