The diameters of 50 steel rods are measured and saved as values of the variable DISTANCE in the following data set: * data measures; input diameter @@; label diameter='Diameter in mm'; datalines; ...

As with all probability distributions, the Normal Distribution describes how the values of your data are distributed. Subsequently, it is one of the most important probability distributions in ...

A Box-Cox Power Transformation allows you to transform data to match a normal distribution. It is not a guarantee of normality. It is a quick way of transforming data to better fit a control chart.

We investigate properties of a diagnostic-envelope method for evaluating normal probability plots of regression residuals that was proposed by Atkinson (1981), implemented by BMDP (Hardwick 1987), and ...

Review challenges in the use of normality testing situations and recommendations on how to assess data distributions in the pharmaceutical development manufacturing environment Statisticians ...

The distances between two holes cut into 50 steel sheets are measured and saved as values of the variable DISTANCE in the following data set: * data sheets; input distance @@; label distance='Distance ...
