Chi 2 Calculator. Chi Squared test is used to find if a sample data is consistent with a hypothesized distribution. Degree of variation is the number of levels of categorical variable by subtracting one with it.
Calculate chi-square distribution or inverse chi-square distribution. The calculation takes three steps allowing you to see how the chi. Determine the critical values chi2_L chi2_alpha2n-1 and chi2_R chi2_1-alpha2n-1 from chi2 statistical table that corresponds to the desired confidence level and the degrees of freedom.
The results are in.
Step 5 Determine the confidence interval. To use the calculator simply input the true and expected values on separate lines and click on the Calculate. To perform a new analysis with a new set of data click the Reset. The first stage is to fill in the group and category information.
