I just found out about this survey showing that people in Western Australia are the nation's unhappiest.
I'm not sure about the study. Seems to me they haven't taken suicide into account. All the suicide victims from the other states have removed themselves from the sample. But here in WA, we're unhappy, but not that unhappy. These respondents get included, though, and that's going to hold down the WA results.
See, it's very important to consider all the factors when you're doing sampling.
