- Tired of all those other boring Weibull videos that just go on and on with whiteboard scribble and a super technical explanation?
Me too, which is why I created an Introduction to Weibull Analysis!
In a introduction to Weibull Analysis, wou will learn how to use Weibull Distributions to predict your product's reliability in a fun, practical, and easy to follow video.

Liked and subscribed cause the video was very practical, even though I am a PhD student in Industrial engineering, I struggle with some of these concepts. Its been a while since I last used the weibull distribution, and this video was a very good reminder of such concepts.... And now I will head the "boring pages" and the heavy calculations....
Ps: Your effort in making a boring topic becoming less boring made me laugh. Thanks mate
Hi Useche,
Thank you for the kind words and I am glad you found this video helpful.
Cheers!
Always knew about how to find MTTF, but this helped me understand how to statistically back my results using wiebull analysis.
I never understood Weibull until watching this video. Thank you!
You are welcome! Thank you for the feedback.
great video.....simply explained
How do I use this for warranty predictions
thanks
what exactly is the differnece between the MTTF and the time value that results of the curve colliding with 63,2 %?
Predicted number of the population that is expected to fail at that point in the test. However, I do not recommend using this value and stick with the MTTF at the given R&C values. The sample size is too small to expect this trend to be consistent for your entire population.
Could you explain where the 95% level come from please 6:14 , Thank you for the video!
Hi Amine,
It was found using a binomial equation for R&C. I arbitrarily selected a allowable failures of 1 and did an extremely rough round up from a reliability of 47% to 50% with a confidence of 95%.
If you would like to get a more detailed explanation on reliability and confidence, check out my video on sample size determination:

Happy New year!
Nice presentation, however, you di not explain how you calculated the confidence ratio!
How to specify the sample size
This can be done using either a non parametric or parametric binomial equation.
How can I use this for my customer data?
Google.
Hi Guia, I will need more specifics. If you would like to find out how I can help. Feel free to reach out to me in one of the links in the description.
very useful and very well explained. the begging for likes and subs was a real turn off though. not sure if i can stomach watching any more videos with that needless groveling.
how can i use this to convince my company that 1 test sample is not enough?
All depends on your system, industry, and application. For most consumer products, I would recommend using the tools learned in this video to show how proper sample size selection is important in making any kind of meaningful and useful reliability predictions. Feel free to reach out to me at one of the links above if you would like to talk further and see how I can help.
