If you've ever scratched your head over the difference between mean, median, and mode, fret not – you're not alone. While they may sound somewhat similar, they serve very different purposes. In other words, they aren't just tongue-twisting words, but essential tools that help us make ...
Mode, Median, Mean
Median 指的是一组数据按大小排序后,位于中间位置的那个数字。 如果数据的个数是奇数,Median 就是正中间的那个数;如果数据的个数是偶数,Median 就是中间两个数的 Mean。 还是用刚才的例子,3、5、7、9 这四个数字,按大小排序后,中间两个数是 5 和 7,它们的 Mean 是 (5+7)/2 ...
Descriptive statistics tell you about the distribution of data points in data set. The most common measures are the mean, median, mode, range, and standard deviation. For all the examples explained below, we will use the following fictional set of math test scores: {44, 51, 72, 72, 88,...
描述性统计学(descriptive statistics):描述性统计是用来概括、表述事物整体状况以及事物间关联、类属关系的统计方法。通过统计处理可以简洁地用几个统计值来表示一组数据地集中性和离散型(波动性大小)。如mean,median,mode,标准差(又名均方差,standard deviation),标准分等。
