均值(Mean): 均值是所有观测值之和除以观测值的数量。数学表达式为: 其中n 是观测值的数量,xi 是第 i 个观测值。均值是最常见的集中趋势度量,适用于对称分布的数据。 中位数(Median): 中位数是将数据按大小顺序排列后位于中间位置的数值。对于偶数个数据点,则取中间两个数的平均值。中位数不受极端值...
On a right-skewed histogram, the mean, median, and mode are all different.In this case, the mode is the highest point of the histogram, whereas the median and mean fall to the right of it (or, visually, the right of the peak). Note thatthe mean willalwaysbe to the right of the ...
