Quartile

A quartile is a type of quantile. The first quartile (Q1) is defined as the middle number between the smallest number and the median of the data set. The second quartile (Q2) is the median of the data. The third quartile (Q3) is the middle value between the median and the highest value of the data set. A quartile is a type of quantile. The first quartile (Q1) is defined as the middle number between the smallest number and the median of the data set. The second quartile (Q2) is the median of the data. The third quartile (Q3) is the middle value between the median and the highest value of the data set. For discrete distributions, there is no universal agreement on selecting the quartile values. This rule is employed by the TI-83 calculator boxplot and '1-Var Stats' functions. The values found by this method are also known as 'Tukey's hinges'; see also midhinge.
