One of the funnest things about playing with data is that you can clash ideas up against one another.

We spend a lot of time trying to get down to facts hidden in numbers. Sometimes, though, it's fun to just push parameters against one another to see what happens.

Take, for example, this data set pulled from the 2011 census. Here we're pitting religion against the hours of unpaid housework individuals say they do. We're not going to make any bold claims about what this data says about a particular religion, but here's a hint: next time you're faced with the decision about which person to bring into your share house, go with the Brethren.

Why? Because 16.4 per cent of people who identified as Brethren in the census said they spend 30 hours or more a week doing unpaid housework. That placed them second behind the Rhema Family Church (17.3 per cent), but there were only 52 people in that church in all of Australia so you would be unlikely to have one on your couch for an interview.

Witches are also among the house proud, with 15.3 per cent in the top housework-hours bracket. Shinto are tidy, too (15.5 per cent).

The faithful less likely to do your dishes include Sikhs, Muslims and Buddhists. About 30 per cent of the people who profess these religions say they do "nil hours" of unpaid housework (29.3 per cent, 28.8 per cent and 27.4 per cent, respectively). This makes them slightly less tidy (in a purely janitorial sense) than Satanists. One in four Satanists say they do no unpaid housework.
