WebWe now conduct the same test using the chi-square test of independence. Step 1. Set up hypotheses and determine level of significance. H 0: Treatment and outcome (meaningful reduction in pain) are independent. H 1: H 0 is false. α=0.05. Step 2. Select the appropriate test statistic. The formula for the test statistic is: WebSB1 = Satorra-Bentler scaled chi-square value for the alternative model. In order to calculate the test statistic, T, we first need to calculate the value cd: cd = (d0 * c0 - d1 * c1)/ (d0 - d1) Once we have calculated cd, we can compute: T = (SB0 * c0 - SB1 * c1)/cd. T is distributed chi-square with degrees of freedom:
