Title:
 Impact of alternative distributions on quantile-quantile normality plot

Language: English

Keywords:
normality
quantile
visualization

Summary:
Many statistical programs use normal quantile-quantile plots for geometrical visualization of experimental data sets. In the paper we observe how normal quantile-quantile points behave when data sets come from alternative distributions, characterized by different kind of departure from normality. Theoretical lines for these distributions are presented in order to observe relationship between type of departure from normality and location points in a normal Q-Q plot. Additionally, the Shapiro-Wilk’s test is applied to check normality of the data sets.
