This document discusses two methods for constructing attitude scales: paired comparison and equal appearing interval technique. It provides definitions and examples of each technique. The paired comparison method involves respondents selecting between two objects according to some criterion, allowing for ranking of items from most to least preferred. The equal appearing interval method involves subject matter experts sorting statements into piles from most favorable to unfavorable to derive scale values. Advantages and disadvantages of each method are listed.

Attitude can be defined as a tendency to

4. 4
Thurstone (1994) defined ATTITUDE as the degree of degree
or negative affect (feeling) associated with some psychological
object like symbol, phrase, slogan, person, institution, ideal or
ideas towards which people can differ in varying degrees.
5. The word scale comes from the Latin word Scala, meaning a ladder or flight of
steps.
An attitude scale is a tool designed to provide a valid, accurate measures of an
individuals social attitude.
An attitude scale is a special type of questionnaire designed to produce scores
indicating the intensity and direction (for or against) of a persons feeling about
an object or event.

6. Paired comparison scale
Developed by Thurstone
It is a psychological scaling method,
and makes possible the quantitative
investigation of all kinds of values and
subjective experiences- Edwards, 1969
Data obtained are ordinal in nature
(arranged or ranked in order of
magnitude).
7. 7
It is a comparative scaling technique
in which a respondent is presented
with two objects at a time and asked
to select one object according to
some criterion.
Example: the respondent can prefer
tea over coffee, sprite over coke etc.
With n brands , n(n-1)/2 paired
comparisons are required.

9. The following is an example that uses the paired comparison analysis to
identify and rank the top motivators for a team.
The team has selected appreciation to be their top motivator, then comes the
financial benefits. this method provide an estimate of the distances between
each of the stimulus with least preference, whose scale value is (arbitarily) to
the level of zero.

10. Advantages
10
Help to set priorities where there are
conflicting resources.
Reliable as it based on systematic
comparative evaluation.
small differences between stimulus
objects can be detected
Easily understood and can be applied.
Tend to reduce halo or carryover
effects from one judgement to others.
Do not allow tests for statistical
inferences.
Particularly useful where
priorities are not clear.
Easy to do if only a few items are
compared.
Disadvantages
11. Developed by Louis Leon
Thurstone in 1928.
First formal method designed to
measure attitude.
made up of statements about
particular issue.
consists of statements which have a
range of weights from high (usually
11) to low (usually 1).
11
Equal appearing interval scale
12. 1. A large number of statements from various shades related to the
attitude being investigated. These are then scrutinised and edited.
2. Large number of judges (50-300) exercising complete detachment
sort out into 11 piles ranging from most favourable to neutral to
most unfavourable.
3. Tabulation are made which indicates the number of who placed
each item in each category.
4. The scale value of a statement is computed as the median to which
it is assigned by the group of judges.
5. median of the frequency ranges from 0 to 11.
6. Final selection is made, taking items or statements for which there
are more judges agreement
Construction of equal appearing scale
12
13. Example:
13
The question and the
subsequent options can be
administered to the
respondents by using either
the mean or the median score
in the below format. The
weights of the statements are
summed and divided by the
number of statements
checked. If a respondent were
to agree with statements 2, 5,
7 and 10; the attitude score is
10.5 + 2.5 + 4.5 + 6.0 = 23.5/4
= 5.8. Dividing the number of
statements puts this score at a
little above the midway point
of the 1-11 scale. This score
indicates that the attitude is
slightly favorable to diversity
hiring in the organization.
14. Advantages
14
Having a clear neutral point on
the scale.This neutral point
allows for absolute interpretation
of scale scores.
Mean or median is always
calculated.
They are two stepped
They are labour intensive
The ratings may be
influenced by the judges
personal attitude.
It does not obtain
information about the
intensity of agreements with
the ratings.
Disadvantages
