What Is A Skewed Distribution? (5 Key Things You Should Know)

WebbA skewed distribution is an asymmetric probability distribution . By asymmetric, we mean that there are more data points (or more probability, or more weight) on one side of the mean than the other (as illustrated in the picture below).
