An educator is interested in researching how teaching methodology (Factor A) and previous experience with the type of test (Factor B) may affect scores on particular exam. The levels of Factor A are a control (implying no special instruction), group instruction, and private tutoring. Levels of Factor B are no prior experience with the test, one prior experience, and 2 prior experiences. Twenty-seven students were available for study. Nine students from each experience level were randomly allocated to teaching conditions. The experiment ran for one month and the final test was administered with following results.

Factor B: Experience Factor A: Teaching Method
Control Group Instruction Private Tutor
None 60 71 77
62 75 77
65 76 79
Once 68 77 79
69 79 82
73 80 84
Twice 70 80 85
73 84 87
75 85 90

a. Set hypotheses and carry out all relevant tests

b. Describe all results and implications which you've discovered.

1. This includes testing for interaction effects.

2. This also implies testing for differences between means of the levels of the factors that are determined to be significant
