Thank you for this, it's a really useful shortcut! There were quite a few complaints from SonarCloud, please have another quick look whether any of these should be addressed. |

@hannahbast We have undone the merge and reopened this PR as #1614. I will address the Sonarcloud problems there. |

Add a new aggregate function
STDEV(X)which computes the (sample) standard deviation, such that a user will not have to repetitively typemath:sqrt(sum(math:pow((X - avg(X)), 2)) / (count(*) - 1)). This is not part of the SPARQL standard, but also doesn't cause any conflicts.
