Nettet24. aug. 2024 · In particular, we say that a distribution is right-skewed if we have a higher probability of finding values to the right of the mean as compared to the left of the mean and vice versa for a left-skewed distribution. Note that a unimodal distribution with zero skewness does not necessarily imply that this distribution is symmetric.

The distribution is said to be left-skewed, left-tailed, or skewed to the left, despite the fact that the curve itself appears to be skewed or leaning to the right; left instead refers to the left tail being drawn out and, often, the mean being skewed to the left of a typical center of the data.
