Weibull Probability Plot

New Member
Hi !
I did a Weibull probability plot following an example posted earlier but when i compared my Plot to that of a Software Package Plot. Its quite different. By time 1000 y plot says there's a 2% chance of failure whilst in the software package plot it says 10% chance of failure, so my plot is must not be correct. Any help on this is highly appreciated. I have attached my Excel file for you to view

Firstly, Please read the site instructions
They tell you to start your own thread

Weibull functions are above my paygrade

1. Don't assume that some expensive software is correct
2. Check it with something like Mathmatica, R etc
3. Ask somebody outside the forums as you aren't using a Weibull function, you are deriving the function from first priniples

Good luck
