冰同学382页R18课后题第8题答案中这段话怎么理解？： If a distribution is positively skewed, the mean of the distribution is greater than its median—more than half of the deviations from the mean are negative and less than half are positive—and the average magnitude of positive deviations is larger than the average magnitude of negative deviations.

Simon同学，上午好。这段话想表达的大意：positively skew就是右偏，此时，均值＞中位数＞众数。
