Damned lies and statistics
One question Charmaine asked was "How many times have you changed the batteries in your house's smoke alarm?". The answer was "Never".
This bit of data is now in the government stats. What I was not asked was, "How long have you lived in your house?" (answer, "Three months") and "Are your batteries OK?" My smoke alarm batteries were fine, when I checked them not long ago. But I can see the screeching headline:
"Ten million per cent of NSW people have never changed their smoke alarm batteries!!"
