Floor effects can lead to positive skew in a distribution.

Question

Quizplus · Accepted Answer

Floor effects occur when a large number of participants score at the lower end of a measurement instrument, which can cause a distribution to be skewed towards the higher end. This is because participants cannot score lower than the lowest possible score on the instrument, resulting in a clustering of scores at the lower end and a longer tail towards the higher end, leading to positive skew.
