A positive skew indicates that the extreme variables are larger than skews the data distribution is such a way it escalates the mean value in a way that it will be larger than the median resulting in a skewed data set. On the other hand, a negative skew indicates that the extreme variables are smaller which brings down the mean value which results in a median larger than the mean.
