In my last video I discussed how to create a chi squared distribution, and that post can be read here:- https://tracyrenee61.medium.com/create-a-chi-squared-distribution-in-excel-b2b113d99c37
In this post I intend to discuss how to create a Weibull distribution in Excel.
The Weibull distribution is named after Swedish mathematician Waloddi Weibull, who described it in detail in 1939, although it was first identified by Rene Maurice Frechet and first applied by Rosen & Ramler in 1933 to describe a particle size distribution.
The Weibull distribution is a continuous probability distribution that can fit an extensive range of distribution shapes. Like the normal distribution, the Weibull distribution is unimodal and describes the probabilities associated with continuous data. Unlike the normal distribution, the Weibull distribution can also model skewed data, even left and right skewed data.
The Weibull distribution can fit a variety of shapes, approximating the normal and other distributions. This distribution can be used in a broad range of settings, such as quality control, capability analysis, medical studies, and engineering. It is also frequently used in reliability analysis and warranty analysis to assess time to failure for systems and parts.
