WebFeb 15, 2024 · The grand total is the number of outcomes for the denominator. Consequently, to calculate joint probabilities in a contingency table, take each cell count and divide by the grand total. For our example, the joint probability of females buying Macs equals the value in that cell (87) divided by the grand total (223). WebNow there will be a variety of models of independence and associations (see the list below). It is natural to think about using the tests we developed for two-way tables on three-way tables. Many of the models we discuss in this lesson correspond to a particular choice of how to turn a three-way table into a two-way table.
