Reliability Distributions and Their Use

How do you use the Weibull Distribution?

It’s just one of many useful statistical distributions we must master as reliability engineers.

Let’s explore an array of distributions and the problems they can help solve in our day-to-day work.

Detailed Information: When confronted with a set of time-to-failure data, what is your go-to analysis approach?

For me, it’s a Weibull plot. It’s quick, often provides some insight to ask better questions, and is easy to explain to others. A histogram is another great starting point.

If we know a little about the data source, we may favor the normal or lognormal distributions. If discreet data, binomial is the first choice, yet Poisson or hypergeometric have uses too.

A basic understanding of statistical distributions provides a way to summarize data, providing insights to identify or solve problems.

In this webinar, we’ll explore a few distributions useful for reliability engineering work and talk about how to select a distribution, the basics of interpreting distributions, and judging if you have selected the right one.
