When negative ('left-skewed'): the left tail is longer; the mass of the distribution is concentrated on the right of a histogram. When positive ('right-skewed'): the right tail is longer; the mass of the distribution is concentrated on the left of a histogram. A normal distribution has a skewness of 0. } \examples{ skewness(runif(1000)) } \seealso{ \code{\link[=kurtosis]{kurtosis()}} }
