So it’s like 3 in the morning and I’m finally done with that damn Stat 422 project. So I shall now show you the basic results, minus all the fancy math and such.

Go!

The Number of Classes Offered by Each College
Agricultural and Life Sciences: 522
Art and Architecture: 209
Business and Economics: 188
Education: 606
Engineering: 647
Letters, Arts, and Social Sciences: 1,419
Natural Resources: 344
Science: 591
TOTAL: 4,526 classes offered

Percentage of Classes that Require Prerequisites, by College (estimated and actual, respectively)
Agricultural and Life Sciences: 25%, 21.6%
Art and Architecture: 25%, 24.9% (holy crap, I was so close!)
Business and Economics: 57.1%, 53.2%
Education: 21.7%, 15%
Engineering: 33%, 32.8% (pretty close here)
Letters, Arts, and Social Sciences: 16.7%, 11.7%
Natural Resources: 15.4%, 11.9%
Science: 36%, 36.5%
TOTAL: 25.1%, 21.8%

Percentage of Classes that Require Prerequisites Outside of the Department, by College (estimated and actual, respectively)
Agricultural and Life Sciences: 5%, 9%
Art and Architecture: 12.5%, 1.9% (haha, wow, that’s way off)
Business and Economics: 0%, 17% (this is even worse!)
Education: 8.7%, 3%
Engineering: 20.8%, 14.8%
Letters, Arts, and Social Sciences: 1.9%, 1%
Natural Resources: 7.7%, 7%
Science: 13.6%, 11.2%
TOTAL: 10%, 6.7%

So here are the final results!

The proportion of University of Idaho courses that require prerequisites was estimated to be 25.14% with a variance of .000858935 and a bound of .0586, or 5.86%.

The proportion of University of Idaho courses that require prerequisites outside of the field of the course in question was estimated to be 10.04% with a variance of .000960987 and a bound of .0619 or 6.19%.

With the bounds in place, the results of these estimates basically tell us that a 95% confidence interval for the proportion of courses offered by the University of Idaho that require prerequisites is between 19.28% and 31%, and that a 95% confidence interval for the proportion of courses offered by the University of Idaho that require prerequisites outside of the field of the course in question is between 3.85% and 16.23%.

Yay!
