Height and width of histogram bars
« on: April 29, 2010, 08:36:17 pm »
width is1  (18.5-15.5=3, so half the width of the 10 to 15 classfor which we do 15.5-9.5=6
height is 6
requency density=frequency /bin size =9/4=3 for 16-18 class

requency density=frequency /bin size =15/6=2.5 for 10-15 class
so heght =3/2.5*5=6
