last year, class of 250 students, top 5 percent was around 3.7
if this year's class has 200 students - what is the likely impact on gpa percentiles?
If the distribution of grades is the same, why would it change? The number of people in the top 5 per cent would change but I don't think the percentage itself would.
Like I said, I am bad with numbers - but the thinking is this - The curve/distribution per class remains the same....but if there are 50 less students in the class, then the liklihood that a student gets A's in every class seems like it would go down as well.
So, say last year's class had 100 people in it with a curve that requires 10% get a 3.7. Say this year's class has 50 people with the same grading distribution. The number of people getting 3.7's is less this year (10 and 5, respectively), but the likelihood of getting an 3.7 is exactly the same (10%) each year, assuming the same distribution is used. Make sense?
Edit: I thought you were talking about an individual class rather than a total GPA.
