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: Statistical inference is basically concerned with drawing conclusions about a population based on samples drawn from it. The probabilistic decision criteria are the very foundation of inferential statistics. The concept of hypothesis testing is presented in and this note is followed by discussion of properties of estimators, small and large ... 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
