Scaling techniques for researcher
During research especially when the concepts we want to measure are complex and abstract and there are no standardized measurement tools available, we face problems of measurement. Alternatively, when we are measuring something which can lead to subject bias like attitudes and opinions, there is a problem of their valid measurement. A similar problem may be faced in a lesser degree while measuring physical or institutional concepts. Therefore, knowledge of some such procedures which may enable accurate measurement of abstract concepts is extremely essential.
Scaling techniques are immensely beneficial for a researcher.
Scaling is the process of assigning numbers to various degrees of attitudes, preferences, opinion, and other concepts. Scaling is defined as a procedure for the assignment of numbers (or other symbols) to a property of objects in order to impart some of the characteristics of numbers to the properties in question.
Scaling can be done in two ways: (i) making a judgement about an individuals characteristics and then placing him on a scale which is defined in terms of that characteristic, and (ii) constructing questionnaires where individual’s responses score assign them a place on a scale. A scale is a continuum, consisting of the highest point and the lowest point along with several intermediate points between these two extremities. These scale-point positions are hierarchically related to each other. Numbers for measuring the degree of differences in the attitudes or opinions are assigned to individuals corresponding to their positions in a scale. Therefore, the term ‘scaling’ implies procedures for determination of quantitative measures of subjective abstract concepts.
