... Ha: Ho is False C. What assumptions about the data must hold true if the ANOVA test is conducted? Random samples of each independent group, normally distributed numbers in each group and equal variances across groups. D.

... The population values ( and true, also called parameters) are different from those which we measure in a sample ( and s) due to sampling error. Classical test theory is concerned with how the measured (i.e. observed) values of x will be related to the true values xtrue. CTT proposes that the obser ...

Hypothesis Testing
... This tool is used to test the relationship between two sources of variation. In statistics, the relationship can be two ways: Independent. There is no relationship at all (Two different populations) Dependent. There is common relationship between them (Same population). This tool is going to tel ...
