ABSTRACT
The various parts of this book have covered statistical theory, probability, sampling distributions, statistical distributions, hypothesis testing, and various statistical tests based on the level of measurement and type of research design. This next section addresses an important area of research related to replicating our findings. Research for many decades involved carrying out a single study, i.e., collection of a single random sample of data from the population. Researchers today are becoming more concerned with validating their research results. Many different approaches have been taken which are discussed in this chapter and subsequent chapters.
