Several references I have looked at define skewness as follows:
mean > median: positive, or right-skewness
mean = median: symmetry, or zero-skewness
mean < median: negative, or left-skewness
Now, if I enter the following data into Excel:
-125, -100, -50, -25, -1, 0, 0, 0
There is more than one way to measure skewness, and with Fisher's
measure (based on the third moment about the mean), it is quite possible to
have mean > median with negative skewness or mean < median with positive
skewness. The magnitude of skewness needs to be considered in standardized

mean = median: symmetry, or zero-skewness
mean < median: negative, or left-skewness
