ヾ(◍°∇°◍)ノ゙Dear candidate,
从题目截图和以下讲义截图来看,分布都有一条长长尾巴在右侧,此时“右偏”
右偏的特点是“中位数<均值”,记忆方法是:在分布中加入一个极端正数会拉大均值,而中位数几乎保持不变,所以均值大于中位数

To learn and at due times to repeat what one has learnt, is that not after all a pleasure? 👍 [thumb-up] Encourage ourself to be better. Good luck with the rest of you studies!~
