Required input

First, select the number of different categories.

Next, enter the number of cases for each category.


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.
