Web3.247. 3.940. 4.865. 15.99. 18.31. 20.48. 23.21. The table tells us that the probability that a chi-square random variable with 10 degrees of freedom is less than 15.99 is 0.90. Therefore, the probability that a chi-square … WebYou could take your calculated chi-square value and compare it to a critical value from a chi-square table. If the chi-square value is more than the critical value, then there is a significant difference. You could also use a p-value. First state the null hypothesis and the alternate hypothesis.

WebMay 30, 2024 · You can find the critical value in a chi-square critical value table or using statistical software. You need to known two numbers to find the critical value: The degrees of freedom (df): For a chi-square test of independence, the df is (number of variable 1 groups − 1) * (number of variable 2 groups − 1).
Webt, chi-square and F tables also have degrees of freedom, where not every df ( ν -) value is tabulated. The critical values mostly † aren't accurately represented by linear interpolation in the df. Indeed, often it's more nearly the case that the tabulated values are linear in the reciprocal of df, 1 / ν. WebFind the critical chi-square value. Step 1: Calculate the number of degrees of freedom.
