the following table shows the age distribution of cases of a certain disease admitted during a year in a particular hospital.find the average age for which maximum cases occured .[find mode]
age no of cases
5-14 6
15-24 11
25-34 21
35-44 23
45-54 14
55-64 5
To find out 'h' and 'l',
lower limit subtract 0.5 and to the upper limit add 0.5 in all the Class Intervals.
so you get
l=34.5
h=10
So mode of the data given
=34.5+ ( 23-21/ 2 . 23 - 21 -14)10
=34.5 +( 2 / 46 - 21 - 14)10
=34.5 + (2 / 11)
=34.5 + 20 / 11
=34.5 +1.8181
=34.5 + 1.82 (approximately)
=36.32 (approximately)
