A study of undergraduate computer science students examined changes
in major after the first year. The study examined the fates of 256
students who enrolled as first-year students in the same fall
semester. The students were classified according to gender and
their declared major at the beginning of the second year. For
convenience we use the labels CS for computer science majors, EO
for engineering and other science majors, and O for other majors.
The mean SAT mathematics scores for the students are summarized in
the following table.
Major | |||
---|---|---|---|
Gender | CS | EO | O |
Males | 628 | 618 | 589 |
Females | 582 | 631 | 543 |
