WebStep 3: Find the critical chi-square value. Since there are four groups (round and yellow, round and green, wrinkled and yellow, wrinkled and green), there are three degrees of freedom. For a test of significance at α = .05 and df = 3, the Χ 2 critical value is 7.82. Step 4: Compare the chi-square value to the critical value. Χ 2 = 34.08 WebQuantitative Methods in Geography: A Lab Manual. In this lab, we’ll learn how to compare means when we have more than two groups, which is known as Analysis of Variance (or ANOVA).
