Median Rank for Single Censored Data


This example validates the median rank calculations for complete data in Weibull++ standard folios.


Reference Case

Table 6.2 on page 283 in the book Reliability Engineering Handbook Vol 1 by Dr. Kececioglu, Prentice-Hall, 1991.


Data

Num. In Stage State F or S Time to Failure
1 F 16
1 F 34
1 F 53
1 F 75
1 F 93
1 F 120
4 S 200


Result

Num. In Stage State F or S Time to Failure Median Rank (%)
1 F 16 6.7
1 F 34 16.23
1 F 53 25.86
1 F 75 35.51
1 F 93 45.17
1 F 120 54.83
4 S 200


Results in Weibull++

The coordinates of each point in the following plot shows the failure time and the corresponding median rank.
