Chapter 9 (Measurement: Scaling, Reliability, Validity) Summary
In this Chapter, I identified what kinds of attitude rating scales and ranking scales can be used in developing instruments after a concept has been operationally defined. I also discussed how the goodness of measures established by means of items analysis, reliability and validity test. Also mentioned was that the Likert scale and other types of interval scales such as the numerical scale is extensively used in Organizational research since they lend themselves to more sophisticated data analysis. Finally mentioned that the goodness of measures in terms of reliability and validity and the various ways in which these can be established.
Knowledge of 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 concepts further facilitates mini-explanatory surveys by managers.
