Example of Bivariate Analysis

Use the Bivariate platform to construct a scatterplot and fit a regression line for two continuous variables. In this example, solubility levels for chemical compounds were measured in different solvents. You want to compare the results of two solvents.

1. Select Help > Sample Data Folder and open Solubility.jmp.

2. Select Analyze > Fit Y by X.

3. Select Ether and click Y, Response.

4. Select 1-Octanol and click X, Factor.

5. Click OK.

6. Click the Bivariate Fit red triangle and select Fit Line.

Bivariate Fit Report

You can see that the two solvents have similar results. The linear model has an RSquare value of 0.87, indicating that the model explains 87% of the variability in the response. Since both the X and Y variables are measurements, one might consider the Fit Orthogonal or Fit Passing Bablok options.
