Median weight of 100 children was 12 kgs. The Standard Deviation was 3.Calculate the percentage coefficient of variance -
We cannot calculate coefficient of variance here, because value of mean has not been provided (value of median is given).
Only in standard normal curve mean = median.
But in that case both are '0' (In standard normal curve mean = median = mode = 0)
I am clueless here.
It you take, value of median as mean than the answer will be 25%.

3/12 x 100 = 25%
25%
35%
45%
555
