This example uses the Consumer Preferences.jmp sample data table to explore the relationship between employee tenure and having school age children. The Employee Tenure column is a numeric column with values 1, 2, 3, and 4. These values have been assigned Value Labels using the Value Labels column property. To evaluate a mean employee tenure using the mean score option in the categorical platform, you need to assign Value Scores to the column values. For more information about column properties, refer to The Column Info Window in the Using JMP book.

Tip: Be aware of how your data is recorded when using the mean score option. If your data is recorded as coded numeric data with value labels, the mean value calculations are based on the numeric data. If the numeric data does not have meaning, use Value Scores to assign meaningful data values to the response levels.
