Question

Which number has the maximum frequency and the minimum frequency in the given data ?

The heights(in cm) of $20$ boys of class $\mathrm{VI}$ are : $140$,$138$,$139$,$140$,$140$,$147$,$139$,$139$,$139$,$139$,$140$,$147$,$138$,$140$,$139$,$140$,$147$,$147$,$138$,$139$

Answer 1

Arranging all the available data in ascending order, we get

$138$,$138$,$138$,$139$,$139$,$139$,$139$,$139$,$139$,$139$,$140$,$140$,$140$,$140$,$140$,$140$,$147$,$147$,$147$,$147$

Frequency of data: The total number of times of recurring of any data is known as frequency of that data.

$139$ is the most recurring number while $138$ is the least recurring number.

Thus, the number with maximum frequency$=$$139$ & the number with minimum frequency$=$$138$
