Webb2 maj 2024 · Step 4. Reject or fail to reject the null hypothesis. Since our test statistic Q (0.5) is less than the critical value (0.526), we fail to reject the null hypothesis. Step 5. Interpret the results. Since we failed to reject the null hypothesis, we conclude that the max value 25 is not an outlier in this dataset. How to Conduct Dixon’s Q Test in R WebbThe null hypothesis is that the means at the two times or under the two conditions are the same in the population. The alternative hypothesis is that they are not the same. This test can also be one-tailed if the researcher has good reason to expect the difference goes in a particular direction.
