The following four 2 3 2 tables, presented without labels or titles, provide simplified opportunities to practice your computational skills. Calculate chi square for each.

HINTS:

● Calculate the expected frequencies for each cell with Formula 10.2. Double-check to make sure you are using the correct row and column marginals for each cell.

● It may be helpful to record the expected frequencies in table format—see Tables 10.4 and 10.8.

● Use a computational table to organize the calculation for Formula 10.1—see Tables 10.5 and 10.9.

● Follow the step-by-step instructions.

● Double-check to make sure you are using the correct values for each cell.
