This bug seems to have already been fixed.
See http://git.savannah.gnu.org/cgit/pspp.git/commit/?id=26ff6fce95fb38f0986017dd922c36d4b1b239c7

So if you upgrade to 0.7.8 you should be fine.

Note also that the definition of "Median" is not well defined. There are at least 5 ways it can be calculated. Examine can
do them all - refer to the manual. Frequencies can only do one
of them (this would not have affected the example you posted).

In contrast to the correct results executed by the EXPLORE command, FREQUENCIES gives wrong result when calculating MEDIAN.

See the attachment!
(of course, same data were used)

Thanks for the PSPP btw!!:)
