The classes in a frequency distribution range from 110 to 170 with class interval being 10.
What is the Mid value of this Class Distribution?
140
The Classes can be shown as :
110 - 120
120 - 130
130 - 140
140 - 150
150 - 160
160 - 170
There are 6 classes in total. The Mid value will be the intersecting point of the 3rd and 4th class
∴ The mid value of the distribution is - 140
We can also find mid value by taking the sum of upper and lower limit and then dividing it by 2.
