Understanding Quantiles

Imagine you have a distribution of numbers, in this case I have aroudn 6000 numbers that vary between 50 and 3233:

> summary(myScore)
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
  50.11  242.40  739.10 1135.00 1826.00 3233.00

If we examine quantiles of the data:

> quantile(1:max(myScore), seq(0,1,by=0.25))
  0%  25%  50%  75% 100% 
   1  809 1617 2425 3233
