The purpose of many research projects is to assess relationships among a set of variables and regression techniques often used as statistical analysis tools in the study of such relationships. In this chapter we discuss the basic ideas of simple regression analysis when only one predictor or independent variable is available for predicting the response of interest. In the interpretation of the primary parameter of our model, we discuss both scales of measurements, discrete and continuous, even though in most practical applications, the independent variable under investigation is often on a continuous scale. A problem solving section appears at the end of the chapter.
