Example of the Factor Analysis Platform

To view an example Factor Analysis report for a data table for two factors:

1.

Select Help > Sample Data Library and open Solubility.jmp.

2.

Select Analyze > Consumer Research > Factor Analysis.

The Factor Analysis launch window appears.

3.

Select all of the continuous columns and click Y, Columns.

4.

5.

The initial Factor Analysis report appears.

Initial Factor Analysis Report

6.

For the Model Launch, select the following options:

–

Factoring Method as Maximum Likelihood

–

Prior Communality as Common Factor Analysis

–

Number of factors = 2

–

Rotation Method as Varimax

7.

After all selections are made, click Go.

The Factor Analysis report appears.

Example Factor Analysis Report

The report lists the communality estimates, variance, significance tests, rotated factor loadings, and a factor loading plot. Note that in the Factor Loading Plot, Factor 1 relates to the Carbon Tetrachloride-Chloroform-Benzene-Hexane cluster of variables, and Factor 2 relates to the Ether–1-Octanol cluster of variables. See Factor Analysis Model Fit Options for details of the information shown in the report.
