Class12: SAT scores
Journal Assignment
Investigate the SAT data.
There are three possible data sets to use. One data set contains data about women
students at Dartmouth, and a second contains data about men students at Dartmouth.
The third data set comes from a study that ETS performed, including students from
a college whose name was not revealed. You do not have to use all three data sets, but you
can if you'd like.
The data will soon be available on the Web (under Class 12 ETS Validation, Dartmouth.men,
Dartmouth.women) and also on the Course Server, in the JMP folder. The data on the
Web is in text format, so you will need to save it off the Web and then "import"
it into JMP. The data in the JMP folder is in JMP format already, so you can either
start up JMP and then "open" it, or just double click on the data set's icon which
will start up JMP automatically. As usual, please email linda@math.princeton.edu
or jlsnell@dartmouth.edu if you have any problems.
Possible questions to investigate include:
- Can you see any difference in the distribution of men's and women's SAT scores?
- How well do SAT scores correlate with college gpa?
- How well does high school gpa correlate with college gpa?
- Are the correlations better for men or women?
- What combination of SAT scores and high scool gpa gives the best predictor of college
gpa?
- Do women's SAT scores underpredict their college gpa's?
- Should SAT scores be used for college admissions?
Or, follow your own interests.
We will also put the smoking data from Class 11 on the Web and on the Course Server
for optional and unrelated investigation.
