Abstract: In this module, we will discuss one of the most important techniques of statistical inference, that is, the process of constructing an interval that is believed to contain the true parameter value with a certain degree of confidence. These kind of intervals are ubiquitous in the statistical literature and forms ... More

Abstract: In this module, we will discuss the procedure of testing statistical hypotheses which is an important arm of statistical inference. This procedure revolves around the specification of two hypotheses (each a statement about the parameter) and them selecting one of those based on some well defined statistical technique. In doing ... More

Abstract: Sampling distribution is a very important technique that helps us to quantify the “precision” of a statistical inferential procedure by analyzing the distribution (hence variability) of sample summaries about the corresponding population parameter. In this module, we will discuss the sampling distribution of the sample mean and proportion in detail. ... More

Abstract: Goodness of fit tests is a statistical technique used to ascertain whether a given sample originates from a particular distribution (or population). There are different kinds of goodness of fit tests based on the context of study and the population of interest. This technical note discusses two of the most ... More

Abstract: The case deals with statistical quality control of foundry defectives by attributes. Specifically, the first two parts of the case pose the problem of designing an appropriate control chart for control of foundry defectives, using identical sample sizes. The third part of the case deals with the development of a ... More
