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 large than the mean for Stock A.
C.The median is less than the mean for Stock B.
解释:
A is correct. 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.For the positively skewed B, the mode is less than the median, which is less than the mean.
老师,negative skewness=left skwenss,positive skewness=right skewness是这样吗
