WebOur chi-squared statistic was six. So this right over here tells us the probability of getting a 6.25 or greater for our chi-squared value is 10%. If we go back to this chart, we just learned that this probability from 6.25 and up, when we have three degrees of freedom, that this right over here is 10%. Well, that's 10%. WebNov 27, 2024 · In this case, the chi-square statistic value comes out to be 32.5. Step 5: Once we have calculated the chi-square value, we will compare it with the critical chi-square statistic value. Then the number of degrees of freedom represents the number of values in the data set that are free to vary and contribute to the test statistic.
