Quintile

In descriptive statistics, quintile is the value that divide a frequency distribution into five equal parts, each containing approximately a fifth of the sample distribution.

People also use quintile as a division in a sample. For example, the first quintile is the point with one fifth of the data below it after ranking all the datas. As one can see here, a quintile will contains approximately 1/5 of the datas as the total number of observations is not necessarily divisible by 5.

Quintile may refer to the following articles:

• Astrological aspect
• Income quintiles
