A. The data is symmetric. B. The data is positively skewed. C. The data is negatively skewed. D. There is not E. nough information to determine the skew. 相关知识点: 试题来源: 解析 C。在一个数据集中,如果众数为 15,中位数为 20,说明数据是负偏态的。因为众数小于中位数,数据在较小的...
Skewness measures the degree of symmetry of a distribution. The normal distribution is symmetric and has askewnessof zero. If the distribution of a data set instead has a skewness less than zero, or negative skewness (left-skewness), then the left tail of the distribution is longer than the ...

The opposite of symmetrical distribution is asymmetrical distribution. A distribution is asymmetric if it is not symmetric with zero skewness; in other words, it does not skew. An asymmetric distribution is either left-skewed or right-skewed. A left-skewed distribution, which is known as a negati...
