It can be easily pictured by looking at {numref}`dataserver_geyser_cdf` which represents the 
cumulative distribution function (CDF) of the attribute $x_2$. The quantile at 50 percent for $x_2$ 
can be seen by drawing an horizontal line at 0.5, the value of interest being the one on the abscissa 
where this line crosses the CDF curve.
