Intensive supervision program for poor student performers
Not what you're looking for?
Suppose that you are interested in determining the effectiveness of an intensive supervision program (ISP) for poor student performers. To examine its effectiveness, you keep track of 12 students entering an ISP for one year and tabulate the number of poor grades they had. You also gather two control groups. The first consists of 12 students who were required to have a proctored study period. The second consists of 12 students who had no intervention. The following results describe the number of new poor grades for each offender in each group during your one-year follow-up:
Nothing Proctored study hall ISP
5 4 5
2 2 2
3 6 1
1 1 6
9 3 0
6 4 4
4 2 3
5 6 7
6 1 0
4 0 2
8 3 3
10 4 1
SUM 63 36 34
Sum of all the data = 133
Sum of the squares of all the data = 715.
Using these data,
1. Identify the independent and dependent variables.
2. What are the null and alternative hypotheses
3. With an alpha of 0.01, test the null hypothesis against the alternative.
4. Find eta- squared. What does it mean?
