Choose the correct answer from the options given below:

Key Points

• A rating scale is a measurement tool used in research, assessment, and evaluation to gather data and assign scores or values to different attributes, characteristics, or behaviours. It allows individuals (raters) to rate the extent to which a person, object, event, or behaviour possesses a specific trait or characteristic.

The limitations of the rating scale being a tool of research are:

• A. Halo effect:
  • ​The halo effect occurs when the rater's overall impression or bias about a person influences their ratings on specific attributes. For example, if a rater has a positive overall impression of an individual, they may rate all attributes higher, regardless of the actual performance.
• B. Rater's tendency to be too generous:
  • ​Some raters may have a tendency to be lenient or too generous in their ratings, providing higher scores than the actual performance warrants.

Options C, D, and E are not limitations of the rating scale:

• C. Difficulty in construction of items:
  • ​This refers to challenges in developing appropriate and meaningful rating scale items, but it is not a limitation of the rating scale itself.
• D. Rater faces difficulty in its administration on the sample:
  • ​This may be a practical issue in the research process, but it is not a limitation of the rating scale as a measurement tool.
• E. Ambiguous language especially for children with disabilities and minorities:
  • This is a concern related to the use of rating scales with specific populations, but it is not a general limitation of the rating scale as a research tool.

So, the correct answer is 1) A & B only.
