Excel / 統計? > Link > 最大と最小を取った平均 @ microsoft

Last updated at Posted at 2016-09-09

N個のデータセットから最大と最小を取った平均を求めるという計算。

For statistical purposes, you may want to calculate the average of a sample excluding its highest and lowest values. In Microsoft Excel, you can create the following formula to calculate an average after excluding the highest and lowest values:

=(SUM(region)-MAX(region)-MIN(region))/(COUNT(region)-2)

その効果はいかに。

ノイズにより飛びぬけておかしい点が最大、最小、各1個ずつある場合は有効なのだろう。ノイズがもっとある場合は効果は薄れるだろう。
