**Question**

If the class mark of a frequency distribution are 29.5,36.5,43.5,50.5,then find the class interval corresponding to the class mark 36.5

19-01-28

**Answer**

Class size = upper limit - lower limit = 36.5 - 29.5 = 7

Now,

Half class size will be =7/2=3.5

Therefore the class interval corresponding to 36.5

36.5+3.5=40

36.5-3.5=33

Class intervals is from 33-40
