单项选择题
If a distribution is positively skewed, then generally you could say:（）
A. mean ＞ median ＞ mode.
B. mean ＜ median ＜ mode.
C. mean ＞ median ＜ mode.
答案
参考答案：A
解析：
When a distribution is positively skewed the right side tail is longer than normal due to outliers. The mean will exceed the median, and the median will generally exceed the mode because large outliers falling to the far right side of the distribution can dramatically influence the mean.
