Additional Examples of the Contingency Platform
2. You can find these probabilities in the Contingency Table. Since the probabilities are computed based
on two levels of sex, which differs across the rows of the table, use the Row% to read the probabilities, as
follows:
P(Married|Female)=0.6884
P(Married|Male) = 0.6121
Therefore, the calculations are as follows:
0.6884
P(Married|Female)/P(Married|Male) = --------------- = 1.1247
0.6121
Example of a Two Sample Test for Proportions
This example uses the Car Poll.jmp sample data table. Examine the probability of being married for males
and females.
1. Open the Car Poll.jmp sample data table.
2. Select Analyze > Fit Y by X.
3. Select marital status and click Y, Response.
4. Select sex and click X, Factor.
5. Click OK.
6. From the red triangle menu next to Contingency Analysis, select Two Sample Test for Proportions.
