Quartiles in statistics are three values such that the lower quartile, second quartile (better known as the median) and upper quartile divide up the set of observations into four subsets with equal numbers in each subset.
- a quarter of the observations are smaller than the lower quartile,
- a quarter of the observations are between the lower quartile and the median,
- a quarter of the observations are between the median and the upper quartile, and
- a quarter of the observations are greater than the upper quartile,
