nitcomp:
ok let me explain...

first things first... u should know this FREQUENCY = HEIGHT X CLASS WIDTH, ok?
lets take the given example...

freq=115
class width=2

with the help of the formula, height= 115/2
                                                        =57.5

now the height (freq. density) SHOULD equal 57.5, but it doesnt..
it equals 11.5 cm..

now u will have to find the "FACTOR'' by which the height is reduced..

11/57.5 which equals 0.2, ok?

now find the supposed height of the other column..

(example..3rd column...)
height = 26/2 = 13...

now multiply 13 into the factor...

13*0.2 = 2.6!
there you go...
same thing with other columns....


if u dont get me, please notify,, i will try again ;D

nitcomp:
aww.. u just got it!
aneways..
i tried!! :)
