To summarize the numbers a bit: Male uploads that were overwritten by anyone: 7226 Female uploads that were overwritten by anyone: 536 None uploads that were overwritten by anyone: 21484
Male uploads that were overwrote anyone: 6775 Female uploads that were overwrote anyone: 619 None uploads that were overwrote anyone: 21861 As a percentage of all overwritten uploads Male: 24.7% Female: 1.8% None: 73.5% As a percentage of all uploads that overwrote someone Male: 23.2% Female: 2.1% None: 74.7% Assuming random assortment, we would expect: Male-male: 0.247*0.232 = 5.7% Male-female: 0.52% Male-none: 18.5% Female-male: 0.42% Female-female: 0.038% Female-none: 1.3% None-male: 17.1% None-female: 1.5% None-none: 54.9% Given the number of events observed, that translates to expectations of: Male-male = 1667 Male-female = 152 Male-none = 5412 Female-male = 122 Female-female = 11 Female-none = 380 None-male = 5003 None-female = 439 None-none = 16061 These numbers are broadly consistent with what you posted. There are some deviations, but given the sample size and the number of possible confounding factors (some of which have been mentioned by others) I think you'd need evidence of a quite large effect before assuming there was an important bias. -Robert Rohde On Fri, Aug 14, 2015 at 2:20 AM, Fæ <fae...@gmail.com> wrote: > I have pulled together the following table together for the past 360 days, > counting whenever an image was reverted by someone who was not the last > uploader, and then attempting to find any declared gender: > > 2014-2015 Commons file overwrite stats compared to gender > > +---------------+----------+ > | sex | count(*) | > +---------------+----------+ > | female-female | 1 | > | female-male | 110 | > | female-none | 426 | > | male-female | 139 | > | male-male | 1376 | > | male-none | 5711 | > | none-female | 479 | > | none-male | 5289 | > | none-none | 15716 | > +---------------+----------+ > > Key: "none" means not set in user preferences, "female-male" means a woman > has overwritten a man's file and "male-none" means a declared male has > overwritten an account with no gender set. > > I'd appreciate any views on whether there is any statistical meaning to be > pulled from these figures, apart from showing that men probably outnumber > women contributors by ten times on Commons. > > If the email is displaying badly, you can find a wiki formatted table and > original generating SQL on the Commons village pump[1].
