In case of negatively skewed distribution, the relationship between mean,median and mode is:
In case of positively skewed distribution, the relationship between mean,median and mode is:
Therefore, for a positively skewed distribution with a mean of m = 20, the median would be less than Mean. Hence the probable value of median is less than 20
