Percentages of how many people get each study score!

[FlorianK]

I just calculated how many percent of all students get a specific studyscore and in which top% a specific study score puts you - can't guarentee that this is true, particularly for subjects with a low amount of students

Have fun

How was this calculated? (they're meant to be normal, mean=30, sd=7)

[paulsterio]

I don't think this is correct, exactly 50% should be above and below 30.

[charmanderp]

How do more people get 50 than do 49? I've never understood that.

[FlorianK]

Mean of 30 sd of 7
X~(30,7)
Getting a 30 in example means, Pr(29.5<X<30.5)

Getting a 50 means Pr(X>49.5)

To any year 12s reading this, don't worry about all these numbers, just do your best.

[abeybaby]

Still a good indicator of where you need to be to get the marks you're aiming for though!

Best and most underrated advice ever.

Did you calculate each percentage individually or did you write up a program/spreadsheet to calculate this?
