5. Whether test items look like they measure the construct






6. Used when n-cases in a sample are classified into categories or cells - tell us whether the groups are significantly different in size - look at the pattern or distributions - not difference between mean - ex:intro psych class categorized into race -

8. Compares 2 groups of people at the same time point






9. Measures the extent to which items in a measure 'hang together' and test the same thing

31. Allow generalization from sample to population - statistics (sample) - parameters (population): use statistics to estimate parameters
