In the research study concerning the effect of social factors on reading and math scores, we found a strong negative correlation between % minority and % poverty and reading scores in Section 3.8.
a. Why is it not possible to conclude that large relative values for % minority and % poverty in a school result in lower reading scores for children in these social classes?
b. List several variables related to the teachers and students in the schools that may be important in explaining why low reading scores were strongly associated with schools having large values of % minority and % poverty.
