Answer 2

The mid value of the first class of the given frequency distribution is 30.

Because mid-value is the middle value of any interval, we will take the average of the interval's lower and middle terms to calculate it. The average is calculated by adding the lower and upper limit intervals and then dividing the result by two.

The given frequency distribution: 10 20 30 40 50

The mid value of the first class of distribution is given by,

As we have 5 numbers and the difference between the numbers is same. We can find the middle value using 2 methods:

1) In the 5 set of numbers we have to consider the number which equally separates the number of values on both of it's either sides.

So, 30 is the middle value.

2) The sum of the first value and last value of the set and then divide it by 2.

= (10+60)/2

= 30.

∴ Hence, the mid value of the first class of the given frequency distribution is 30.
