Figure 6.9 Example of Analysis of Means for Proportions
Figure 6.9 shows the proportion of patients who were on-time from each clinic. From Figure 6.9, notice the
following:
• The proportion of on-time arrivals is the highest for clinic F, followed by clinic B.
• Clinic D has the lowest proportion of on-time arrivals, followed by clinic A.
• Clinic E and clinic C are close to the average, and do not exceed the decision limits.
Example of Correspondence Analysis
This example uses the Cheese.jmp sample data table, which is taken from the Newell cheese tasting
experiment, reported in McCullagh and Nelder (1989). The experiment records counts more than nine
different response levels across four different cheese additives.
1. Open the Cheese.jmp sample data table.
2. Select Analyze > Fit Y by X.
3. Select Response and click Y, Response.
The Response values range from one to nine, where one is the least liked, and nine is the best liked.
4. Select Cheese and click X, Factor.
A, B, C, and D represent four different cheese additives.
5. Select Count and click Freq.
6. Click OK.
