Since the p-value (0.01697) is less than our alpha level of 0.05, we reject the null hypothesis of our test. We have sufficient evidence to say that our results are statistically significant at alpha level 0.05.
WebMar 26, 2024 · The test is known as a goodness-of-fit χ 2 test since it tests the null hypothesis that the sample fits the assumed probability distribution well. It is always right-tailed, since deviation from the assumed probability distribution corresponds to large values of χ 2. Testing is done using either of the usual five-step procedures.

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: granite boronia life cycleWebThe chi-square statistic is the sum of these values for all cells. Interpretation.
