WebMay 9, 2024 · chisq = scipy.stats.chisquare (data, fit_line) But I got negative values, which doesn't make sense in terms of a chi squared value... however this arises because my data (and hence best fit line) is all negative. I then came across the answer here regarding the R^2 approach, but I do not know how to interpret this. WebΧ 2 = 8.41 + 8.67 + 11.6 + 5.4 = 34.08. Step 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
WebLike the F test, also the Chi-square test is usually one-tailed. The desired size of the test is achieved by appropriately choosing a critical value in the right tail of the Chi-square distribution. The null is rejected if the Chi-square statistics is larger than the critical value. Learn more about regression analysis
