It characterizes the extent to which the distribution of a set of values deviates from a normal distribution. Skewness between -0.5 and 0.5 is symmetrical. Kurtosis measures whether data is heavily left-tailed or right-tailed.

The normal probability plot is formed by plotting the sorted data vs. an approximation to the means or medians of the corresponding order statistics; see rankit. Some plot the data on the vertical axis; others plot the data on the horizontal axis. Different sources use slightly different approximations for rankits. The formula used by the "qqnorm" function in the basic "stats" package in R (programming language) is as follows: Web(e.g., construct and interpret scaled picture/bar graphs, line plots with measurement data) o Grades 6-8 (e.g., sampling populations; construct and interpret dot plots, histograms and box plots; graph bivariate data) o.
