DISCUSSION QUESTIONS  209

                             scales such as the numerical scale, are extensively used in organizational research since
                             they lend themselves to more sophisticated data analysis. Finally, we discussed the good-
                             ness of measures in terms of reliability and validity and the various ways in which these
                             can be established.
                               Knowledge of the different scales and scaling techniques helps managers to administer
                             short surveys by designing questions that use ranking or rating scales, as appropriate.
                             Awareness of the fact that measures are already available for many organizational con-
                             cepts further facilitates mini-exploratory surveys by managers.
                               In the next chapter, we will see the different sources and methods of data collection.



                                 DISCUSSION QUESTIONS AND POINTS TO PONDER

                             1. Briefly describe the difference between attitude rating scales and ranking scales and
                               indicate when the two are used.
                             2. Why is it important to establish the “goodness” of measures and how is this done?
                             3. Construct a semantic differential scale to assess the properties of a particular brand of
                               coffee or tea.
                             4. Whenever possible, it is advisable to use instruments that have already been developed
                               and repeatedly used in published studies, rather than develop our own instruments for
                               our studies. Do you agree? Discuss the reasons for your answer.
                             5. “A valid instrument is always reliable, but a reliable instrument may not always be
                               valid.” Comment on this statement.


                                                        EXERCISE

                               which is the one preferred most by students.
                             c. To what extent do individuals agree with your definition of accounting principles.
