The cutting process is in statistical control. As a preliminary step in a capability analysis of the process, it is decided to check whether the distances are normally distributed. The following ...

You can use a graphical Probability Plot or a statistical test like the Anderson-Darling test and use the p-value to test whether your data is non-normal.

This paper considers the problem of choosing a plotting position to use in constructing a normal probability plot. Previous recommendations have focused primarily on choosing a position so that the ...

When you request a lognormal probability plot, you must specify the shape parameter for the lognormal distribution (see Table 9.13 for the equation). The value of must be positive, and typical values ...

A t-distribution is a type of probability function that is used for estimating population parameters for small sample sizes or unknown variances.
