  • 3. Chi-Square Calculator for 5 x 5 (or less) Contingency Table

    This is a chi-square calculator for a simple 5 x 5 contingency table (for alternative chi-square calculators, see the column to your right). The first stage is to fill in the group and category information. So, for example, if you have collected data on smoking habits, and want to find out whether smoking is related to gender, you could have "Male" and "Female" as the two groups, and "Smoking" and "Non-Smoking" as the two categories.

      Category 1 Category 2
    Group 1
    Group 2
    Group 3
    Group 4
    Group 5
