Which is more affective, ratings vs. recommendation
7 Jul 2009 - 4:41pm
When you are presenting data, please include a measure of variability
and a distribution of scores. The 3.5/5 rating could mean a bunch of
2s and a bunch of 5s and you might have a bimodal distribution which
might have some design implications. I see so many reports where
there is no indication of variability or the actual shape of the curve
formed by the individual ratings.
A mean without a measure of variability is pretty weak in my view
since you don't know what the shape of the distribution is.
