I still don't have my question answered from Statistics Probability/ Still waiting....but here is another question.

High School students were given a short course in basic algebra. Students were randomly assigned to one of the following conditions:courses lasting for 5, 10, or 15 sessions. At the conclusion of the course, participants were asked to take an exam which included several math problems.Before taking the test, participants in each group were offered a monetary incentive-no money,$ 15.00 or $ 30.00 for a certain level of performance. The researcher collected the number of correct answers on the math exam for each participant.

Make sure you include the question number, question and the answer.If any of these items is missing points will be deducted

4.Identify the factorial design

Question: Is this a 3 x 3 factorial design?

A with 3 levels, b with 3 levels, c with 3 levels

and 9 conditions:

5 sessions with $30

10 sessions with $30

15 sessions with $30

5 sessions with $15

10 sessions with $15

15 sessions with $15

5 sessions with $0.0

10 sessions with $0.0

15 sessions with $0.0

I read another answer to this question that someone asked and they said it was a 2 x 2 factorial design. Which answer is correct?
