Definitions for "Quartile"
One of four segments of a distribution that has been divided into quarters. For example, the second-from-the-bottom quartile of an income distribution is those whose income exceeds the incomes of from 25% to 50% of the population.
In statistics the quartile point is the spot where one quarter of the items in a series is on one side and three quarters are on the other side. For example, if a series of numbers was 1, 3, #, 4, 5, 7, 10, 20 and 30, the quartile point (#) would be between 3 and 4.
One of a set of numbers (a quantile) on the random-variable axis that divides a probability distribution into four equal areas. The three quartile points that lie between the extremes of the distribution are designated as 3 and are defined in terms of the distribution function () as follows: Thus, 2 coincides with the median. In empirical relative frequency tables, the quartiles are estimated by interpolation. The interquartile range is the distance from 1 to 3; half of this distance is called the semi-interquartile range (or quartile deviation) and is sometimes used as a crude measure of variability or spread.
Same as Quadrate.
