For example, if you order by math SAT scores, then the result is one of the math SAT scores.
You cannot order by one column and get a percentile value for a different column. expr3 This is the optional expression used to group rows into partitions. Returns Returns the value that is at the specified percentile.
Description This function computes the p-value (two-tails test) of a given z.
