To compute the value of the test statistic we must first computed the expected number for each of the six core cells (the ones whose entries are boldface): 1 st row and 1 st column: 1 st row and 2 nd column: 1 st row and 3 rd column: 2 nd row and 1 st column: WebFeb 17, 2024 · Compare the test statistic X2 to a critical value from the Chi-square distribution table. Compare the p-value of the test statistic X2 to a chosen alpha level. Test statistics are calculated by taking into account the sampling distribution of the test statistic under the null hypothesis, the sample data, and the approach which is chosen for ...
WebTo conduct this test we compute a Chi-Square test statistic where we compare each cell's observed count to its respective expected count. In a summary table, we have r × c = r c cells. Let O 1, O 2, …, O r c denote the observed counts for each cell and E 1, E 2, …, E r c denote the respective expected counts for each cell. WebFor two-sided tests, the test statistic is compared with values from both the table for the upper-tail critical values and the table for the lower-tail critical values. The significance level, α , is demonstrated with the …
WebWe use a chi-square distribute table to look up the critical value for α = .05 and df = 6. Then, we compare that value with the test statistic. See the table below. Step 6: Interpret the results. If the test statistic > critical value, then the p-value (α) for the test statistic is < the p-value for the critical value (0.05). WebKey Results: P-Value for Pearson Chi-Square, P-Value for Likelihood Ratio Chi-Square. In these results, the Pearson chi-square statistic is 11.788 and the p-value = 0.019. The likelihood chi-square statistic is 11.816 and the p-value = 0.019. Therefore, at a significance level of 0.05, you can conclude that the association between the variables ...
