Heights of 12 boys (in cm) are given as:
143,144,141,145,147,147,142,145,149,151,147,143.
Which is the height with maximum frequency?
On observing the collected data,
143,144,141,145,147,147,142,145,149,151,147,143
We see that 147 cm is the height occurring maximum number of times (3 times) in the data. Hence, 147 cm is the height with maximum frequency.
