5) While comparing the same individuals three different times with an interest in three variables, which design is appropriate?
A) One way within subjects ANOVA B) One way between subjects ANOVA
C) Three way within subjects ANOVA D) Three way between subjects ANOVA
Answer: D. Three way between subject ANOVA
Explaination: Here, no. of dependent variable= 1 and No. of independent variable = 3
Three way between subjects ANOVA is used to determine whether there is three way relationship among variables on an outcome(dependent variable). Therefore, three way between subjects ANOVA is appropriate.

6. Typically, when comparing a within-subjects design to a between-groups design which of the following describe their differences in error variance? a. Within-subjects designs results in less error variance than between-groups. b. A within-subjects design results in more error variance than a between-groups design. C. A within-subjects design results in the same amount of error variance as a between-groups design d. There is no error variance in a within-subjects design, whereas a between- groups design does present some error variance....

All the response variables within the k populations follow a normal distributions. b. The samples associated with each population are randomly selected and are independent from all other samples. c. The response variable within each of the k populations have equal variances. d. All of the above. 5. The t test for the difference between the means of two independent...

An instructor in a statistics class wants to evaluate the effectiveness of three teaching assistants using different instructional methods (1: small group work, 2: lecture, and 3: individual work with TA help). For one class session, the students are equally and randomly assigned into one of the three groups, each of which receives a lecture on “ANOVA” from one of the teaching assistants. At the next meeting of the class, the students are given a quiz on the material. To...
A within-subjects design is to the whereas a between-subjects design is to the a. Repeated-measures ANOVA; One-way ANOVA. b. One-way ANOVA; Chi-square test for independence, c. One-way ANOVA; Repeated-measures ANOVA. d. Dependent samples t-test; Repeated-measures ANOVA

If the researcher uses a repeated-measures design, how many individuals are needed for the study?" a 12 b 24 c 36 d 48 "You have to find the F-critical for each effect when running a two-factor, independent measures, ANOVA. " True False "After you remove the individual differences in a...

One treatment is significantly more effective in shortening the recovery time. B. There are some significant differences in recovery time after the four treatments. C. All treatments are equally effective in shortening the recovery time. D. There is no significant difference in recovery time after the four treatments. 2.For a one-factor...

State whether each of the following is an example of a between-subjects, mixed, or within-subjects two-way ANOVA design. (a) A psychologist administers a small, medium, or large dose of a drug to a sample of mice (Factor A: drug dose) and measures reward-seeking behavior across three experimental trials (Factor B: trials). between-subjects design or mixed design or within-subjects design (b) An industrial organizational psychologist measures the GPA among men and women graduate students (Factor A: gender) with low, medium, or...
