A set of data arranged in order with values that partition the data into three groups, each containing one-third of the total data. To define these terciles, the historical data is arranged in order from lowest to highest and then the data is partitioned into three equal groups. The lowest third of the data values are defined as the lowest tercile, the middle third of the values are the middle tercile and the upper third of the values are the upper tercile. A tercile is a specific form of quantile.
按順序排列的一組數據，其值將數據分成三組，每組包含總數據的三分之一。 爲了定義這些 terciles，歷史數據按照從最低到最高的順序排列，然後將數據劃分爲三個相等的組。 最低的三分之一的數據值定義爲最低的 tercile，中間的三分之一是中間的 tercile，上面的三分之一是上面的 tercile。 Tercile 是分位數的特定形式。
For example, if you had 100 data values, the lowest tercile would contain the 1st–33rd data values, the middle tercile the 34th–67th values and the upper tercile the 68th–100th values.
例如，如果您有100個數據值，最低 tercile 將包含第1-33個數據值，中間 tercile 包含第34-67個數據值，上面 tercile 包含第68-100個數據值。
