Question

the utility of mode calculation in statistic ​

Answer 1

The formula used is l×{f1-f0÷2f1-f0-f2}×h

Answer 2

Mode means the observation that is repeated the most number of times.

Mode formula for grouped class intervals

l + (f1 - f0)/(2f1 - f0 - f2) × h

Mode in normal observations

Eg: 7, 6,8,1,4,7,8,7,9,7

Here 7 repeats the most number of times

So 7 is the mode.
