Example of Bivariate Analysis
This example uses the SAT.jmp sample data table. SAT test scores for students in the 50 U.S. states, plus the
District of Columbia, are divided into two areas: verbal and math. You want to find out how the percentage
of students taking the SAT tests is related to verbal test scores for 2004.
1. Open the SAT.jmp sample data table.
2. Select Analyze > Fit Y by X.
3. Select 2004 Verbal and click Y, Response.
4. Select % Taking (2004) and click X, Factor.
5. Click OK.
Figure 4.2 Example of SAT Scores by Percent Taking
You can see that the verbal scores were higher when a smaller percentage of the population took the test.
