but im being thick and finding that hard to work out.
if i have 50 random numbers between 76 and 126 how can i find it out?
edit: do i find the median of the cumulative frequency and times it by 0.75 for UQ and 0.25 for LQ?

i believe so
u have a graph, u draw a horizontal line from 75% on the y axis to where it meets the x axis, anything above is the upper quartile
u draw a horizontal line from 25% on the y axis to where it meets the x axis, anything below is the lower quartile
at least thats what i remember from gcse, i could b wrong

in that case
i THINK what you wanna do is write them out in ascending order, and the first 1/4 is the lower quartile and the last 1/4 is the upper quartile, i THINK
