Common Rating Scales
* Binary
* Likert
* Semantic Differential
* Guttman


Binary Scale
Binary scales are nominal scales comprising of binary items that expect one of two conceivable qualities, for example, yes or no, true or false.


Likert Scale
Composed by Rensis Likert, this is an extremely famous rating scale for measuring ordinal information in social science research.


Semantic Differential Scale
This is a composite scale where respondents are requested to show their sentiments or emotions toward a single proclamation utilizing distinctive sets of descriptors surrounded as perfect inverses.


Guttman Scale
Outlined by Louis Guttman, this composite scale utilizes a progression of items masterminded in expanding request of force of the construct of interest, from minimum exceptional to generally extraordinary.

Scaling
Based on Stevens statement, scaling is the process of assigning of objects to numbers as indicated by a run the show. This procedure of measuring theoretical ideas in solid terms stays one of the most troublesome assignments in observational social science research. The result of a scaling procedure is a scale, which is an experimental structure for measuring items or markers of a given construct. Comprehend that scales are somewhat unique in relation to rating scales. A rating scale is utilized to catch the respondents’ responses to a given thing, for example, for example, a nominal scaled thing catches a yes/no response and an interim scaled thing catches an incentive between strongly disagree to strongly agree.

Scales can be unidimensional or multidimensional, in light of whether the basic construct is unidimensional or multidimensional. Unidimensional scale measures constructs along a single scale, going from high to low. Note that a portion of these scales may incorporate multiple items, yet these items endeavor to measure the same basic measurement. This is especially the case with numerous social science constructs, for example, selfesteem, which are expected to have a single measurement going from low to high.

Multidimensional scales, then again, utilize distinctive items to measure each measurement of the construct independently, and after that join the scores on each measurement to make a general measure of the multidimensional construct. For example, scholarly inclination can be measured utilizing two separate trial of students’ mathematical and verbal capacity, and after that consolidating these scores to make a general measure for scholastic bent.


Popular Unidimensional Scaling
* Thurstone’s equal-appearing scaling
* Likert’s summative scaling
* Guttman’s cumulative scaling

Thurstone’s equal-appearing scaling
Louis Thurstone, is one of the soonest and most popular scaling scholars, distributed a technique for equal-appearing interims in 1925. This strategy begins with an unmistakable theoretical meaning of the construct of interest. In view of this definition, potential scale items are produced to measure this construct. These items are created by specialists who know something about the construct being measured. The underlying pool of hopeful items ought to be worded in a comparable way, for example, by surrounding them as proclamations to which respondents may agree or disagree.


Likert’s summative scaling
The Likert technique, a unidimensional scaling strategy created by Murphy and Likert, is potentially the most prevalent of the three scaling approaches. Similarly as with Thurstone’s technique, the Likert strategy additionally begins with an unmistakable meaning of the construct of interest, and utilizing an arrangement of specialists to produce around 80 to 100 potential scale items.


Guttman’s cumulative scaling
Composed by Guttman, the cumulative scaling strategy depends on Emory Bogardus’ social distance technique, which expect that individuals’ readiness to take an interest in social relations with other individuals differ in degrees of force, and measures that power utilizing a rundown of items masterminded from slightest extreme to generally exceptional. The thought is that individuals who agree with one thing on this rundown additionally agree with every single past thing. By and by, we only from time to time locate an arrangement of items that matches this cumulative example superbly.
