An experiment concludes that there are significant differences among treatments, with “F(2,27) = 7.62, p < .01, η2 = 0.28.” If the same number of participants was used in all of the treatment conditions, then how many individuals were in each treatment?

Which of the following represents the total percent of scores that fall within 1 standard deviations of the mean?

Calculate the range for the scores in Group A Group A: 20, 100, 12, 79, 88, 35, 91, 43, 156Group B: 232, 78, 62, 33, 90, 21, 15, 67, 23

On the past ACT, the mean is a 30 and the standard deviation is 2.5. What is the z-score for someone who scored a 40?

How would you describe the mode of this data set?5, 6, 2, 3, 9, 0, 8, 3, 7, 5

What are the df values for a repeated measures ANOVA with four treatment conditions where n=12?

Calculate the range for the scores in Group A Group A: 20, 100, 12, 79, 88, 35, 91, 43, 156Group B: 232, 78, 62, 33, 90, 21, 15, 67, 23

A researcher calculates an independent-measures t statistic of t = 2.38 for a study comparing two treatments with a sample of n = 14 in each treatment. What is the correct decision for a regular two-tailed hypothesis test?

A researcher conducts an experiment comparing two treatment conditions with 20 scores in each treatment condition. If a repeated-measures design is used, how many subjects are needed for the experiment?

A Factorial ANOVA has 4 levels for factor A and 8 levels for factor B and uses 9 participants in each treatment condition. What is the total number of participants needed for the study?
