Plotting on Weibull Paper

This report explains Weibull plotting and its rationale. It shows how the two Weibull parameter estimates are easily read off from the Weibull plot. The use of Weibull plotting is introduced first in the context of complete samples and then extended to two common forms of censoring: type I or multiple censoring and type II censoring. Two blank Weibull plotting templates are provided, one for a two cycle log10 scale and the other for three cycle log10 scale on the abscissa. The use of a Weibull plot as a diagnostic tool for checking the Weibull assumption underlying the sample is examined critically. For small sample sizes, answers, if obtained via this tool, should be taken with caution, since the variability of such Weibull samples is still substantial.
