Graph A is skewed right, while Graph B is skewed left. With right-skewed graphs, the mean always comes to the right of the mode (i.e., the peak). (图源:Asitgoes/Wikimedia Commons)下图是右偏态分布:那么现实生活中哪些数据会是右偏态分布呢?举个栗子 ...
在处理非正态分布数据时，首先需要回顾一些基础统计知识。模（Mode）是数据中出现频率最高的数值，范围（Range）是数据中最大值与最小值的差值，中位数（Median）是按照数据从小到大排序后的中间值，平均值（Mean）是所有数据之和除以数据个数。对于右偏态分布，平均值位于模的右侧；左偏态分布则相反...
Left Skewed Distribution A left skewed distribution, also known as a negatively-skewed distribution, has a tail that extends towards the lower values. The majority of the data is concentrated towards the higher values. No Skew Distribution A no skew distribution, also known as a symmetrical distri...

According to a set of data. In a sample of n = 124 selected from a left-skewed population, x = 68 and s = 22. Would you use the t-test to test the null hypothesis H0: mu = 63? Explain. If you use a 0.05 level of significa...

Negative, or left-skewed refers to a longer or fatter tail on the left side of the distribution, while positive, or right-skewed, refers to a longer or fatter tail on the right. These two skews show the direction or weight of the distribution. The three probability distributions below are ...
