Why is an explanation required? Any developer worth his or her salt knows that, statistically, something like this is bound to happen over enough companies and enough years, even if the trend is so heavily skewed the other way. Is this a 3 sigma deviation? Maybe. Or could it be that, on average, women might be drawn to educational software more than other types? Doesn't sound unreasonable. Regardless, your insistence on an explanation shows that you're still stuck in the bad old days.
