In this article, the focus is on the estimation of Weibull percentiles by considering weight functions and probability estimators. The percentiles are estimated by weighted linear regression method and analytical method. The criterion of study is to observe smaller standard deviation in choosing the best method of estimation. The best combination of weight function and probability estimator is observed and the comparison is done with the analytical method to decide the best method of estimation. Simulation study is carried out by MATLAB. The best method of estimation of Weibull percentiles is applied on real life data sets. This study will be useful to observe statistical variation in the fracture strength of brittle materials like ceramics, glass, fibers.
