A percentile is the cost of a variable lower which a certain percent of explanation fall. So the 20th percentile is the charge (or make) below which 20 percent of the notes may be found. The term percentile and the interrelated term percentile rank are often used in colorful statistics as well as in the coverage of scores starting norm-referenced tests.

The 25th percentile is also recognized as the primary quartile; the 50th percentile as the middle.

One designation is that the pth percentile of n well thought-out values is obtained by first scheming the rank k = \frac{p(n+1)}{100}, rounded to the nearest integer and then captivating the value that corresponds to that grade. One alternative technique, used in a group of applications, is to use a linear exclamation between the two nearest ranks in its put of rounding.

Linked with the percentile purpose, there is also a biased percentile, where the percentage in the whole mass is counted instead of the total numeral. In most worksheet applications there is no average meaning for a weighted percentile.
