Data - Test for Equal Variances
main topic        

The data can be entered in the following ways:

·    Enter the response data in a single numeric column. Provide 1 to 9 factor columns to identify the group or factor level for each row. The factor columns can contain numeric data, text data, or date/time data.

·    Enter the data for each group or factor level in a separate numeric column.

Outliers can have a strong influence on the results, especially if the sample sizes are small. You should try to determine the cause of any unusual observations and correct any measurement mistakes or data entry errors. Consider removing data that are associated with special causes.
