u see how many numbers there are..lets say theres 28..
the interquartile range 25-75% so its from the 7th number to the 21st number...
i hope

praise897 is correct - if your brother knows how to draw a box plot (which he should), the inter-quartile range is the width of the box.

i just covered this for my term 3 test...u find the 3rd quartile (75%) and minus it from 1st quartile (25%)...its pretty simple but its easy to forget..like most of math..hehehe
