YOU NEED TO GO THE WEBSITE BELOW, ONCE YOU ARE THERE, look at the different groupings on the SAT scores and then answer the questions at the bottom

Put in interval values of 10, 20, and 50 and discuss how that changes the findings. Which do you think is most appropriate and why? Would you choose different parameters depending on whether you wanted to make a point about scores being relatively uniform, or that higher scoring students are relatively unusual?
