Since Gnumeric is open source, the easiest way of checking this is to
check the source.

Perhaps for C programmers, not for me :)

Looking at the source an obvious typo is visible but that typo will onl
affect the efficieny of the calculation for an even number of
observations with the two central values not equal but it will not
affect the result.
SSMEDIAN is supposed to calculate the median as described in "Using
Basic Statistics in the Social Sciences" by Annabel Ness Evans.

Thank you, that is exactly the information I am after!
