When a distribution is skewed to the right, this means there is a
a. Positive skew
b. Negative skew
c. No skew
d. Multi-skewed
Homework Answers
Option A is correct as in the case of the positive skewness the distribution is skewed right and in case of the negative skewness the distribution is skewed left.
As the skewness is defined as the degree of distortion from the set symmetrical bell curve or we can say that the from the normal distribution.
