WebMeans without common letters are significantly different (Tukey–Kramer HSD test). (B) Cells were treated with 100 ng/mL DON for 0 and 8 h to measure abundance of mRNA encoding key ER stress markers (qPCR) and * denotes significant effect of treatment (Student t-test, n = 4). Tukey's range test, also known as Tukey's test, Tukey method, Tukey's honest significance test, or Tukey's HSD (honestly significant difference) test, is a single-step multiple comparison procedure and statistical test. It can be used to find means that are significantly different from each other. Named … See more 1. The observations being tested are independent within and among the groups. 2. The groups associated with each mean in the test are normally distributed. 3. There is equal within-group variance across the groups associated … See more The Tukey confidence limits for all pairwise comparisons with confidence coefficient of at least 1 − α are Notice that the point estimator and the estimated variance are the same as those for a single … See more • Family-wise error rate • Newman–Keuls method See more Tukey's test is based on a formula very similar to that of the t-test. In fact, Tukey's test is essentially a t-test, except that it corrects for family-wise error rate. The formula for … See more The Tukey method uses the studentized range distribution. Suppose that we take a sample of size n from each of k populations with … See more Both ANOVA and Tukey–Kramer tests are based on the same assumptions. However, these two tests for k groups (i.e. μ1 = μ2 = ... = μk) may result in logical contradictions when k> 2, even if the assumptions hold. It is possible to generate a set of … See more • Montgomery, Douglas C. (2013). Design and Analysis of Experiments (Eighth ed.). Wiley. Section 3.5.7. See more
