Document Summary

Parametric test: a statistical procedure that requires that the characteristic studied be normally distributed in the population and that the researcher have interval data. Nonparametric test: a statistical procedure that makes no assumptions about the way the characteristic being studied is distributed in the population and requires only ordinal or nominal data. Power of a test: the ability of a statistical test to reject the null hypothesis when it is actually false and should be rejected. Chi-square: a nonparametric test of significance whereby expected frequencies are compared against observed frequencies (cid:229) observed frequencies: in a chi-square analysis, the results that are actually observed when conducting a study. Expected frequencies: the cell frequencies expected under the terms of the null hypothesis for chi-square.
