Quartile

In descriptive statistics, the quartiles of a ranked set of data values are the three points that divide the data set into four equal groups, each group comprising a quarter of the data. 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.

Quartiles

The lower and upper quartiles (this term was first used by Galton, 1882; also referred to as the .25 and .75 quantiles ) are the 25th and 75th percentiles of the distribution (respectively). The 25th percentile of a variable is a value such that 25% of the values of the variable fall below that value.
Similarly, the 75th percentile is a value such that 75% of the values of the variable fall below that value and is calculated accordingly.
