Variation Research - A Practical Method of Significance Testing in Fatigue 640163

The testing of materials involves the evaluation of the contributions made by various factors to the quality of a product. To say that a factor is important, we must have a sound statistical basis. If a factor is irrelevant, we must also have a firm basis for saying that it is. The technique of variation research makes use of probability paper plots and demonstrates the statistical ideas of significance in a fashion easy to understand and easy to interpret. An exposition of the main points of variation research in materials testing is the purpose of this presentation.
