Rating scales

 Rating Scales: Rating scales is a list of behaviours made into a scale, using frequency of behaviour, level of mastery, etc., which the observer checks before, during, or after the behaviour. These scales are used in recording behaviour at frequent intervals throughout a sample of social interactions and are found in one or a combination of three basic forms which are as follows:

Numerical rating scale: A numerical scale is a rating scale that is used to measure or identify quantitative data. The data is analyzed using statistical methods and results can be displayed by use of charts, tables, histograms and graphs. They are very simple to construct. Easy to use and convenient in data analysis.

Forced-choice rating scale: This rating scale is used to reduce bias and establish objective standards of comparison between individuals, but it does not involve the intervention of a third party. Although there are many variations of this method, the most common one asked raters to choose from among groups of statement those which best fit the individual being rated and those which lest fit him. The statements are then weighted or scored, very much the way a psychological test is scored.

Graphic rating scale: A Graphic rating scale refers to any rating scale that consists of points on a continuum and it is a label that is given to a wide category of rating formats. This is a scale which people use to indicate ratings of a particular attribute. A straight line may be represented by descriptive phrases at various points. To rate the subject for a particular trait a check mark is made at the particular point.
