17. Chi Square A. Chi Square Distribution B. One-Way Tables C. Contingency Tables D. Exercises Chi Square is a distribution that has proven to be particularly useful in statistics. The ﬁrst section describes the basics of this distribution. The following two sections cover the most common statistical tests that make use of the Chi Square Chi-Square Test of Association between two variables The second type of chi square test we will look at is the Pearson’s chi-square test of association. You use this test when you have categorical data for two independent variables, and you want to see if there is an association between them. Statistical tables: values of the Chi-squared distribution. Critical values of the chi-squared distribution STATISTICAL TABLES 1 TABLE A.1 Cumulative Standardized Normal Distribution A(z) is the integral of the standardized normal distribution from −∞to z (in other words, the area under the curve to the left of z). It gives the probability of a normal random variable not 18.05 Tables Since we generally have access to computers there is no need for the comprehensive tables of old. These tables are designed to be complete enough and easy to use for exams. Standard normal table of left tail probabilities. Standard Normal, T, Chi-Squared Tables The Chi‐Squared Statistic •Chi‐square statistic measures the difference btbetween the obdbserved counts and the counts that would be expected if there were no relationship between two categorical variables. •Large differences are evidence of a relationship.

As a result, for any given level of significance, the critical region begins at a larger chi square value, the larger the degree of freedom. Figure J.1 shows the shape the comprehensive tables of old. These tables are designed to be complete enough and easy to use for exams. Standard normal table of left tail probabilities.

### chi square value is 14.067. This means that for 7 degrees of freedom, there is exactly 0.05 of the area under the chi square distribution that lies to the right of ´2 = 14:067. The second page of the table gives chi square values for the left end and the middle of the distribution. Again, the ﬁs across the top represent 913

tables of the percentage points of the chi-square distribution. The present author has, however, recently encountered applications (see Harter, 1963 a and b) for (vi) From α and k − 1, a critical value is determined from the chi-square table. (vii) Reject H0 if χ2 is larger than the critical value (right-tailed test). Example 1: The Chi-Square Test of Independence is used to test if two categorical variables are associated.

Therefore, the probability that a chi-square random variable with 10 degrees of freedom is greater than 15.99 is 1−0.90, or 0.10. ‹ Chi-Square Distributions up Trick To Avoid Integration › Printer-friendly version. 5.Proportions & contingency tables-hypothesis test of a proportion-con dence intervals for proportion(s) - ˜2 (Chi-square) goodness of t test - contingency tables (testing two proportions) - McNemar’s test for paired Bernoulli trials-sensitivity and speci city-odds ratios and relative risk 1/44 ˜
