An independent-measures research study was used to compare two treatment conditions. The first treatment had n=13, a mean of M=74 with a variance of s²=9, and the second treatment had n=11, M=61 and s²=6. Do these data indicate a significant difference between the two treatments? use a two-tailed test with αα=.05. Be Be sure to show all formulas with symbols (and plug in numbers), steps, processes and calculations for all parts of all answers.

As H0 is rejected at 5% los, we conclude that the claim is true that the there is significant difference between the treatments.

A researcher uses an ANOVA to compare nine treatment conditions with a sample size of n = 13 in each treatment. For this analysis find the degrees of freedom. What is df(treatment)? This is sometimes referred to as the “numerator degrees of freedom.” What is df(error)? This is sometimes referred to as the “denominator degrees of freedom.” If the scenario was changed so that there were still nine treatments, but there were different sample sizes for each treatment (a.k.a. an...
