The percentile of a given value is determined by the percentage of the values that are smaller than that value.
For example we can have the $25^{th}$ percentile is the value below which 25 percent of the observations may be found.
The 25th percentile is called as the first quartile (Q1), the 50th percentile as the median quartile (Q2), and the 75th percentile as the third quartile (Q3).
In general, percentiles and quartiles are specific types of quantiles.
