Statistical problems can be classified according to the types of variables observed. Two different criteria for distinguishing variables are important in this book. First, it is convenient to differentiate between (i) responses and (ii) explanatory variables (which affect the responses). In a given problem how one makes the distinction depends on the study design and the scientific goals of the investigation. Second, variables can be distinguished according to their scale of measurement. Four measurement scales are described below.
