This document discusses different types of structured self-report instruments and rating scales that can be used to collect information. It describes four main types of rating scales: graphic rating scales, numerical rating scales, descriptive rating scales, and comparative rating scales. A common example of a rating scale discussed is the Likert scale, which uses a series of statements followed by response options to assess attitudes. The document outlines the uses, characteristics, types (including common 5-point scales), advantages, and disadvantages of Likert scales as a structured self-report instrument.

3. Rating Scale
A rating scale is a set of categories designed to elicit information
about a quantitative or a qualitative attribute
The most common example is the Likert scale, star rating, and
slider.
There are four types of rating scales that can be used effectively:
1.Graphic rating scale.
2.Numerical rating scale.
3.Descriptive rating scale.
4.Comparative rating scale.

4. 1.Graphic rating scale.
This type of evaluation lists the traits required for the job and asks the source to rate the
individual on each attribute such as dependability and creativity.
For example, the ratings can include a scale of 1–10; excellent, average, or poor; or exceeds,
meets, or does not meet expectations.

5. 2.Numerical rating scale.
In numerical scale the observer or rater is supplied with a
sequence of numbers which is well defined and his task is to rate
the objects on the given sequence of numbers on the basis of
his impression.

6. 3.Descriptive rating scale.
It does not use number but divide the assessment into series
of verbal phrases to indicate the level of performance.

7. 4.Comparative rating scale.
Comparative Rating Scale: Comparative rating scale, as the name
suggests, expects respondents to answer a particular question
in terms of comparison,

rating scales that can be used effectively:
•Graphic rating scale.
•Numerical rating scale.
•Descriptive rating scale.
•Comparative rating scale.

9. Structured Self Report
Self-reported measures are measures in which respondents are
asked to report directly on their own behaviors, beliefs, attitudes, or
intentions.
For example,
common measures of rating Scales such as Thur-stone scales,
Likert scales, and semantic differentials are self-report
instruments.

10. The Likert Scale
A measure of attitudes designed to allow
respondents to rate how strongly they agree or
disagree with carefully constructed statements,
ranging from very positive to very negative
attitudes toward some object.
A Likert scale consist of a series of statements
each followed by a series of response alternative
for the respondent to express himself or herself
about the statement. 10

11. In a Likert scale the most common number of alternative
is five because it often respondents a sufficient range of
choice without requiring unnecessarily minute
distinctions in attitudes.
strongly agree, agree, uncertain, disagree, and strongly
disagree

12. Uses
To measure attitude values and feelings of
about specific concepts , quantifying the
qualitative attributes
Characteristics
• Psychological
• measurement tool
• Illustrative in nature
• Neutral statement
• Bipolar scaling methods 12

13. Types of Likert Scales
2-point Likert scale
3-point Likert scale
4-point Likert scale
5-point Likert scale
7-point Likert scale

• Easy to administer
Disadvantages
