2)An Institute of professionals examined the effect of a computer learning program on math ability. The researcher also was interested to see if the math ability of the student influenced the efficacy of the program. Groups of low and high math ability students learned a list of new math techniques using either the standard (control) method or the computer program method. Scores were calculated at the completion of each program. The score was based on how many math problems they got correct.

Students with Low Math ability used the standard method	Students with High Math ability used the standard method	Students with Low Math ability used the computer method	Students with High Math ability used the computer method

This is under the ANOVA lesson and I wanted to learn how to determine the independent and dependent variables, I believe there are two of each? What are they as well to make sure?
