a) What is the appropriate test statistic?
---Select--- na one-way ANOVA within-subjects ANOVA two-way ANOVA

b) Obtain/compute the appropriate values to make a decision about H0.
Time: critical value =   ; test statistic =  
Decision:  ---Select--- Reject H0 Fail to reject H0

Instructor: critical value =   ; test statistic =  
Decision:  ---Select--- Reject H0 Fail to reject H0

Interaction: critical value =   ; test statistic =  
Decision:  ---Select--- Reject H0 Fail to reject H0


c) Compute the corresponding effect size(s) and indicate magnitude(s).
Time: η2 =   ;  ---Select--- na trivial effect small effect medium effect large effect
Instructor: η2 =   ;  ---Select--- na trivial effect small effect medium effect large effect
Interaction: η2 =   ;  ---Select--- na trivial effect small effect medium effect large effect

ANSWER:

a) What is the appropriate test statistic?
two-way ANOVA

b) Obtain/compute the appropriate values to make a decision about H0.
Time: critical value = 7.636 ; test statistic = 2.359
Decision: Fail to reject H0

Instructor: critical value = 5.453 ; test statistic = 5.746
Decision: Fail to reject H0

Interaction: critical value = 5.453 ; test statistic = 3.859
Decision: Fail to reject H0

c) Compute the corresponding effect size(s) and indicate magnitude(s).
Time: η2 = 0.060 ; small effect
Instructor: η2 = 0.290 ; medium effect
Interaction: η2 = 0.195 ;  small effect

Max is taking two courses this semester Math and Economics. She has 10 hours to study and has a mid-term for each class coming up. Both tests are over 100 points. Suppose that if she goes to the Math or Econ tests without studying at all she will get a 0. For every hour that Max studies for the math mid-term her grade goes up by 8 points and for every hour she studies for econ mid-term, her grade goes...

We wish to determine if two instructors teaching the same introductory course have significantly different “DF rates” (defined as the proportion of students who receive a course grade of D or F among all students who complete the course).Each instructor teaches 60 students. Among the first instructor’s students, 21 receive a D or F. Among the second instructor’s students, 16 receive a D or F. Assume these can be treated as independent simple random samples from their respective populations. Use...
