Zusammenfassung:Ultrasonic flaw detection data susceptible to influence of inspection factors disperse largely. To see the extent and cause, standard deviation has been analyzed in a number of papers on the factors of team, detector etc. This analysis does not lead to general conclusion, and where factors compound each other, the application is limited. This report is an explanation how variance analysis method is applied to solve the problem.
