One of my many pet peeves is that people can't scale on a range from one to ten. For some reason everybody always seem to skip 1-5, which basically gets rounded off to a 1 or a 0 (if they could).
Also 10s are rarely given, since most people only use this for perfect things, and as we all know, perfect things are pretty rare.
Case in point, a friend was asked to rate her day on the scale to ten. She said 7.5, which seemed a bit high, as she previously had stated it was a bit meh. Then I asked her to rate it on a five star rating. She gave it 2 stars. Which is a 4 on the to 10 scale. Quite the difference and probably way more accurate.
So if you ever have to measure response and you don't want too much bias in your numbers: stick to the five star rating.
