Define 'observation'. If by this, you mean 'whenever I spot a hijab I know it's a muslim', that's not really scientific. How do you identify a muslim who's not wearing a hijab?

Maybe it's different for me being in a university setting, but most students I would suspect are muslim based on their names aren't wearing hijabs, in fact it's rare. And I don't think I've ever had a muslim student going full ninja (burka), although I did have one wearing the semi-ninja (everything covered but the face).
