ABSTRACT
This chapter deals with the issue of reliability, and addresses the issue of validity briefly because the two words are so often linked together, and many budding researchers get the two mixed up. It explains the theoretical and statistical procedure on which coefficient alpha is based and more briefly, do the same for split-half reliability. The chapter presents the example that will be used to demonstrate coefficient alpha and split-half reliability. It discusses the two types of reliability Chronbach’s alpha and split-half reliability. Split-half reliability is most frequently used when the number of items is large and it is possible to create two halves of the test that are designed to measure the same thing. Reliability Analysis is a popular and frequently used procedure and the Statistical Package for the Social Sciences method of accessing reliability analysis is user friendly and largely intuitive.
