+# Sketching Quantiles and Ranks Tutorial
Streaming quantiles algorithms, or quantiles sketches, enable us to analyze the distributions
of massive data very quickly using only a small amout of space.
They allow us to compute a quantile values given a desired rank, or compute a rank given

Given *r*, search the rank array until we find the adjacent pair *{r1, r2}* where *r1 <= r < r2*. Return the quantile associated with *r2*, the second of the pair.
