Right-Skewed Distribution: What Does It Mean?

WebJul 23, 2024 · Limits such as $2\sigma$ and $3\sigma$ originated because a normal distribution with parameters $\mu$ and $\sigma$ has about 95% of its probability in the interval $\mu \pm 2\sigma$ and about 99.7% of its probability in $\mu \pm 3\sigma$. In particular, less than 0.00135 or 0.135% of observations will fall above $\mu + 3\sigma.$ WebFor a skewed distribution, both the mean and the standard deviation are affected by the skew in a way that make the z -score results less representative of what you're trying to convey.
