- In Randomized Block Design ANOVA, when should we perform Tukey-Kramer multiple comparison analyses, and why?for a one factor anova comparing four treamtnets, what is the null hypothesisIn a completely randomized design, 12 experimental units were used for the first treatment, 15 for the second treatment, and 20 for the third treatment. Complete the following analysis of variance. At a .05 level of significance, is there a significant difference between the treatments?
- If the results of a two-factor ANOVA show no main effect for factor A but show a significant interaction, then the results indicate that factor A has no effect on the subjects' scores. True or FalseIn randomized block ANOVA, what is meant when we say thata. there is a treatment effect?b. there is a blocking effect?In a randomized controlled trial with two treatment groups, what sample size is necessary to detect a clinically significant difference between the groups with a certain level of statistical power, given the anticipated effect size and the variability in the outcome measure, and how can the trial design be optimized to minimize potential biases and confounding factors?
