Quizplus · Accepted Answer

Skewness is calculated based on the deviation of the data from its mean. Therefore, the mean needs to be calculated first. The median can also be helpful in determining the skewness, but it is not necessary. The mode and variance, on the other hand, do not provide sufficient information to calculate skewness.
