The heights (in cm) of 22 students were recorded as under:

125, 132, 138, 144, 142, 136, 134, 125, 135, 130, 126, 132, 135, 142, 143, 128, 126, 136, 135, 130, 130, 133.


Prepare a frequency distribution table, taking equal class intervals and starling from 125-130, where 130 is not included.

The frequency distribution will be as follows
