Selection bias in iTunes app store ratings

Selection bias (e.g. Berkson’s bias) is a distortion of evidence or data that arises from the way that the data are collected. It is sometimes referred to as the selection effect. The term “selection bias” most often refers to the distortion of a statistical analysis, due to the method of collecting samples. If the selection bias is not taken into account then any conclusions drawn may be wrong.
