Entered in Minitab as: Analyzed as a Cross Tabulation and Chi-Square analysis the results are: The expected values are calculated as follows: r Row total (Column total / Grand total) Example: 100 (186/200) 93.

Returning to our example, before the test, you had anticipated that 25% of the students in the class would achieve a score of 5. The chi-square value is determined using the formula below: X 2 = (observed value – expected value) 2 / expected value. What is the formula for chi square in math? Minitab displays each cell’s contribution to the chi-square statistic, which quantifies how much of the total chi-square statistic is attributable to each cell’s divergence. How is the chi square statistic calculated in MINITAB? Each chi-square test can be used to determine whether or not the variables are associated (dependent). Minitab performs a Pearson chi-square test and a likelihood-ratio chi-square test. Chi-Square Test Chi-Square DF P-Value Pearson 11.788 4 0.019 Likelihood Ratio 11.816 4 0.019 When to use Pearson chi square and likelihood ratio? Use the p-values to evaluate the significance of the chi-square statistics. In these results, both the chi-square statistics are very similar. Use the chi-square statistics to test whether the variables are associated. How to test the significance of chi square statistics? ![]() The chi-square distribution table with three probability level is provided here. Ratio Chi-Square will result in slightly different answers. The chi-squared test is done to check if there is any difference between the observed value and expected value. The Pearson Chi-Square results from Minitab should match the answers in the book. Two times the number of degrees of freedom is equal to the variance.
