Any statisticians out there?? Where would a 3.81 fall? Forum

[UnKnO]

I am mathematically disabled. Where would a 3.81 fall on a cuve (what %) with the following data points? Any help would be much appreciated.

GPA 3.81

25% - 3.358

33% - 3.262

50% - 3.071

No way to know unless we know the distribution of the curve. But I suspect its really fucking high.

If its Gaussian solve the cdf

You find out what *tile position (median, quartiles, etc.) you're in without having access to all the other GPAs in the population (edit: or as the above poster says, you need info on the distribution). For instance, most of the top 25% might be clustered in one chunk in the 3.85-4 range, which means you would end up close to 25%. In contrast, if all those in the top 25% are clustered near the 3.3 threshold, then you might end up being top 1%. Bottom line: no one can answer your question.

Depends if your school ranks current class or uses rolling tables. It's probably ~ Top 5% or so on a distribution (see thesealocust math), but in a given class with a B median, you could be in the top few people. No curve requires that someone get straight A's; it's entirely possible for 1 or no people to do that in a semester.

You're just too high to really say with statistical certainty.
