问题如下：
Stock A has a skewness of -1.58 while Stock B has a skewness of 3.15.Which of the following statements is least accurate?
选项：
A. The mean is larger than the mode for Stock A.
B. The mode is larger than the mean for Stock A.
C. The median is less than the mean for Stock B.
解释：
A is the answer
Stock A with negative skewness has a long tail on its left side, the mean is less than the median, which is less than the mode, so choice B is correct. For the positively skewed B, the mode is less than the median, which is less than the mean, so choice C is correct.
Thus, choice A is least accurate.
感觉左偏右偏都知道，只是均值中数中位数老是对不上
