ABSTRACT
Measurement is a procedure in which a researcher assigns numerals (numbers or other symbols) to empirical properties (variables) according to rules. It is closely linked to the research approach and questionnaire construction which were discussed in Chapters 4 and 6 respectively.There are four levels of measurement: nominal, ordinal, interval and ratio. In some cases your research involves a search for a measure that is already developed and in other cases you need to design a measure. This chapter focuses on these levels of measurements in order to prepare the ground for the next exciting chapter: analysis of the results. This chapter also provides a statement of probability which is an important term to understand in testing your research hypothesis. The contents of Chapter 7 are illustrated in Figure 7.1.
