... result with expected frequencies being less than 5, dissatisfying assumption (2). Two parameters are then identified: degrees of freedom, and α. The parameter degrees of freedom is one less than the number of categories. The parameter α is a value used in statistics that corresponds to the probabili ...

... *When checking the Normal condition on an AP exam question involving inference about means, be sure to include graphs. Don’t expect to receive credit for describing graphs that you made on your calculator but didn’t put on paper. *When a significance test leads to a fail to reject H0 decision, as in ...
