Because the SAT scores for incoming class of students as significantly and severely skewed – thus violating the assumption of normality – you dichotomized the students into two SAT groups coded zero and one. Students that scores below the median score of 1000 on the SAT were given a code of 0, and classified as the Low SAT students. Students that scored 1000, or above, on the SAT were given a code of 1, and classified as the High SAT students.
