Try...

=PERCENTILE(IF(RangeX="Criteria",RangeY),k)

....confirmed with CONTROL+SHIFT+ENTER, not just ENTER.

Hope this helps!

Hello,
How do I create conditional percentiles based on one set of attribute. For
example given a large salary dataset with 50 job titles create salary
quintiles by job title. Can the PERCENTILE function be used?
Thanks - Philippe.
