Assume that Data Set C depicts scores for 30 individuals who participated in a two-way independent groups design. Analyze the data using a two-way ANOVA and complete an ANOVA table reporting the relevant DD, df, MS, and Fs. Make sure to also report each of your critical values and indicate whether you would reject each of your three null hypotheses (i.e., main effect of A, main effect of B, interaction of A x B) Data Set C Variable B Variable...
Apply the techniques of two-way ANOVA to a data sample split into eight treatments with total degrees of freedom, df = 47, testing at the 2.5% level of significance.

21. In one-factor ANOVA for independent samples, which of the following reflects a random variability of scores in the samples? A. MSbetween B. MStotal C. MSwithin D. A & B 22. A one-factor ANOVA is used to evaluate the mean differences in cognitive task performance between three experimental groups, with n = 15 participants in each group. If the computed F = 3.17, which of the following is the correct statistical decision? A. Reject the null hypothesis with either α...

Homework8 Name and types DUE: April ANOVA theory 17, 2019 1) Why can we not do a series of t-tests when comparing more than two groups? 2) For an ANOVA, in English, what is the null hypothesis? The alternative? What would it mean to reject the null? How is this different than when we reject the null in a t test? 3) If I told you I ran a three-way MANCOVA, what could you tell me about my design and...
Data Conduct an independent samples t-test (a.k.a., between-subjects design). Each sample should have at least n=8 individuals. What to turn in: 1. What is your research question? 2. State the null (Ho) and alternative (H1) hypotheses. 3. Conduct the hypothesis test using an alpha level of .05, and state your conclusion (Reject Ho/Fail to Reject Ho) regarding the original hypotheses. 4. Calculate and interpret a measure of effect size (est. Cohen's d or r2) and a 95% confidence interval. Subject...

Let x be a random variable that represents hemoglobin count (HC) in grams per 100 milliliters of whole blood. Thenx has a distribution that is approximately normal, with population mean of about 14 for healthy adult women. Suppose that a female patient has taken 10 laboratory blood tests during the past year. The HC data sent to the patient's doctor are as follows.16181719141314171610(i) Use a calculator with sample mean and standard deviation keys to find x and s. (Round your...
For either independent-measures or repeated-measures designs comparing two treatments, the mean difference can be evaluated with either at test or an ANOVA. The two tests are related by the equation F=12. The following data are from a repeated-measures study: Person Difference Scores 3 I 4 2 3 7 M = 4.00 T = 16 SS = 14 Treatment II 7 11 6 10 M 8.50 T-34 SS = 17 3 3 Mo 4.50 SS = 27.00 Use a repeated-measures t...
