A study conducted by a university researcher of 30 classrooms in a large school district obtained a positive correlation between teachers’ skill in implementing a new math program in the fall and the average math score of children in their classrooms in spring. Although it could be that effective use of the math program raised test scores, another explanation of the results could be that
   a. more talented math teachers were better at implementing the new math program.
   b. teachers with the lowest performing math students were most likely to work hard at implementing the new math program.
   c. use of the new math program was unrelated to children’s math scores.
   d. children’s scores tend to go up anyway at the end of the year.
