Quartiles in statistics are the numbers that divide a given data set into four parts.

Quartiles are calculated by diving a data set by four using the formula: n / 4

There are three quartiles in a data set, namely:

1. 25th percentile, lower quartile or first quartile
2. 50th percentile, middle quartile or second quartile
3. 75th percentile, the upper quartile and third quartile.
