摘要
Instructions were developed for statistical analysis of the laboratory fatigue data step-by-step. Practical cases for solving several questions raised in the treatment of test data,which involved estimation of necessary sample size,verification of the statistical equivalence of the collated sets of data,and determination of characteristic curves in different cases,were given by using the methods and formulae in the document IIW-XIII-2138-06 （best practice guide on the statistical analysis of fatigue data） as a demonstration of various statistical methods of developing a sound procedure for creating reliable calculation rules for the fatigue analysis.
