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 (Q 1) is defined as the middle number between the smallest number and the median of the data set. The second quartile (Q 2) is the median of the data. The third quartile (Q 3) is the middle value between the median and the highest value of the data set. Use the median to divide the ordered data set into two halves. 2  If the median is a datum (as opposed to being the mean of the middle two data), include the median in both halves. 3  The lower quartile value is the median of the lower half of the data.
