One-Way Analysis of Variance (ANOVA) Example Problem
... ANOVA allows one to determine whether the differences between the samples are simply due to random error (sampling errors) or whether there are systematic treatment effects that causes the mean in one group to differ from the mean in another. Most of the time ANOVA is used to compare the equality of ...

Chapter 17 Conditions for Inference about a Mean Standard Error
... The t confidence interval and test are exactly correct when the distribution of the population is exactly normal. No real data are exactly Normal. The usefulness of the t procedures in practice therefore depends on how strongly they are affected by lack of Normality. A confidence interval or signifi ...

A Simple Introduction to Markov Chain Monte–Carlo Sampling
... samples are generated by a special sequential process. Each random sample is used as a stepping stone to generate the next random sample (hence the chain). A special property of the chain is that, while each new sample depends on the one before it, new samples do not depend on any samples before the ...
