One-way Chi-squared test

Description

The one-way Chi-squared test allows to test the statistical significance of differences in a one-way classification system.

This test is not performed on data in the data table, but on statistics you enter in a dialog box.

Required input

First, select the number of different categories.

Next, enter the number of cases for each category.

Results

The results section contains the Chi-squared value, the Degrees of Freedom and associated P-value.

If the calculated P-value is small (<0.05), then there is a significant difference between the frequencies of the different categories.
