ANOVA was developed by the English statistician, R.A. Fisher (1890-1962). Though initially dealing with agricultural data[1], this methodology has been applied to a vast array of other fields for data analysis. Despite its widespread use, some practitioners fail to recognize the need to check the validity of several key assumptions before applying an ANOVA to their data. It is the hope that thi...

A drug company wants to investigate the uniformity of one of its products. It has 2 Sites at which the drug is manufactured. From each site three Batches are obtained at random. From each batch 5 samples (pills) are taken at random. The samples are analyzed for Content. One issue is whether the two sites differ; another is whether batch-to-batch variability within the two sites is a significant...

A project suitable for use as a first and last assignment given in an introductory experimental design course is outlined, and its implementation discussed. Phase 1 of the project is designed to be given at the beginning of a first course in experimental design and involves designing an experiment within instructor-specified parameters based initially on intuition and common sense. Phase 2, at ...

As is discussed by Walker, Abraham De Moivre first discovered the Normal distribution in 1733. This theoretical distribution has since been found to model many real life situations well, including distributions of heights and weights. It is very important in statistical theory, for example via the Central Limit Theorem (CLT). Though this theorem assists us in control chart methodology, it serve...
