title: A pocket-calculator algorithm for the Shapiro-Francia test for non-normality: an application to medicine.
abstract: An easy-to-calculate approximation to the Shapiro-Francia W' test and its P-value is proposed. Its accuracy is sufficient for practical application in samples of size 5 or larger.
