Let us write the mean number of mangoes kept in 50 packing boxes. [using any method]

Answer :

Arithmetic mean of grouped frequency distribution is found by taking out midpoints of the class intervals.

Let’s create a table showing frequencies and fixi.

So, we have

∑fixi = 2736

∑fi = 50

Using the direct method, we have the formula for arithmetic mean.

Using the above values, we get

Mean = 54.72

Thus, mean is 54.72.
