Scale is a tool by which individuals are
distinguished as to how they differ from one
another on the variables of interest.

A scale that allows a researcher to assign
subjects to certain categories or groups
Categories should be mutually exclusive and
exhaustive
◦ e-g, Gender
Male
Female

4.
A scale that allows the researcher to characterize
the variables in such a way so as to denote
differences among various categories and also
rank them in some order
◦ e-g:Please rank the following motivation factors, from 1 to
the most important and 4 the least important)

An interval scale allows us to perform certain
arithmetical operations on the data collected
from the respondents e-g,

The ratio scale overcomes the disadvantage of
the arbitrary origin point of the interval scale, in
that it has an absolute (in contrast to arbitrary)
zero point, which is meaningful measurement

◦ e-g, How many organizations did you work for before
joining this system?

11. In its most basic form, attitude scaling requires
that an individual agree with a statement or
respond to a single question.
This type of self-rating scale merely classifies
respondents into one of two categories.
THE PRESIDENT SHOULD RUN FOR RE-ELECTION
_______ AGREE
______ DISAGREE
Based on Nominal Scale
12. A category scale is a more sensitive measure than
a scale having only two response categories - it
provides more information.

13. An extremely popular means for measuring
attitudes. Respondents indicate their own
attitudes by checking how strongly they agree or
disagree with statements.
Response alternatives: “strongly agree”, “agree”,
“uncertain”, “disagree”, and “strongly disagree”.

16. A series of seven-point bipolar rating scales.
Bipolar adjectives, such as “good” and “bad”,
anchor both ends (or poles) of the scale.
A weight is assigned to each position on the rating
scale. Traditionally, scores are 7, 6, 5, 4, 3, 2, 1,
or +3, +2, +1, 0, -1, -2, -3.
Based on Interval Scale
18. Numerical scales have numbers as response
options, rather than “semantic space’ or verbal
descriptions, to identify categories (response
positions).

19. Modern versions of the Staple scale place a single
adjective as a substitute for the semantic differential
when it is difficult to create pairs of bipolar adjectives.
The advantage and disadvantages of a Stapel scale,
as well as the results, are very similar to those for a
semantic differential. However, the stapel scale
tends to be easier to conduct and administer.
Interval Scale

Divide 100 points among each of the following brands
according to your preference for the brand:
Brand A _________
Brand B _________
Brand C _________
Ordinal Scale: as unclear distance/interval
22. Magnitude of each alternative known
Equal value can be indicated.
Too many can confuse
23. A graphic rating scale presents respondents with
a graphic continuum.

24. easy to construct and simple to use,
can discern fine distinctions, but not
very reliable, can be treated as
interval data.
25. Ranking tasks require that the respondent rank
order a small number of objects in overall
performance on the basis of some
characteristic or stimulus.

26.
Rank the following in order of preference, 1
being the most preferred and 3 the least:
Brand A _________
Brand B _________
Brand C _________
27.
In paired comparisons the respondents are presented with two
objects at a time and asked to pick the one they prefer.
Ranking objects with respect to one attribute is not difficult if
only a few products are compared, but as the number of items
increases, the number of comparisons increases geometrically
(n*(n -1)/2).
It causes fatigue and respondent no longer carefully
discriminate among them.
Example:
Which support provides you more motivation to complete your
task?
friends support
family support
28. 3.A COMPARATIVE SCALE
A COMPARATIVE SCALE provides a benchmark to assess attitudes toward
current object, event or situation understudy.
Please indicate how the amount of authority in your present position
compares with the amount of authority that would be ideal for this position.

29. 4.Forced Choice

another, among the alternatives provided.

30. Two important guidelines are:
1. Relevancy ask only questions that are relevant to the
research objective.
2. Accuracy ask only questions that will provide accurate
information.
31. •Need to decide how “what is to be asked” should be phrased
•Alternative question formats are shown below
•Each format has its advantages and disadvantages

32. 1.
Open-ended – Questions in which the
respondent answers in his own words
Why do you like studying at UCP?
Why do you fly with Airlines X, Y or Z?
How do you assess the economic prospects of Pakistan?
2. Closed-ended (or Fixed Alternative) – Question
in which respondent selects one or more options
from pre-determined set of responses
33. Simple dichotomy Closed ended question with only
two response alternatives
EG: What do you consult while preparing for the
examination?
PPT-slides prescribed course literature
◦
◦
Multiple Choice Closed ended question with more
than two response alternatives
Which is your preferred place to sit in an aircraft: First
Class, Business Class, Economy Class)
34. Checklist question - Multiple choice question in which respondent can
select more than one of the response alternatives
What sources of information would you use to compile your research
paper:
-
Local bookstores
University libraries
Research Institutes
The Digital library
Technical Journals
Magazines and Newspapers
Interviews with Key Stakeholders
35.
1.
Response categories provided for each close-ended
question should be mutually exclusive and exhaustive
Mutually Exclusive Response categories must be
such that the same respondent cannot be classified
into more than one category.
e.g. the categories
$1,000-5,000 and
$5,000-10,000 are not mutually exclusive.
2. Exhaustive – Response categories should include all
possible response options. Sometimes this is achieved
by including a response option like “Other (Please
specify)….”
36. Avoid complexity: use simple, conversational
language.
Avoid leading and loaded questions.
Avoid ambiguity: be as specific as possible.
Avoid double barreled items.
Avoid making assumptions.
Avoid burdensome questions.
37. Leading question: a question that suggests or implies a certain
answer.
Causes:
•The bandwagon effect – e.g. Most Saudis have stopped
eating junk food. Do you eat junk food?
•Partially mentioning some alternatives – e.g. which fast food
restaurant do you prefer, Pizza Hut or others?
•Questions with the phrase: “ Don’t you think that ..”
38.
A question that is designed to suggest a socially
desirable answer. Usually it is emotionally charged.
Causes:
• Choice of words; e.g. using emotionally-charged words,
such as in: In your opinion is it fair that the Security Dept
should be harassing students with parking tickets?
•Do you think that older people should be laid off?
• Framing question such that honest answer is painful or
embarrassing use counter biasing statement.
There are pros and cons to retaining senior citizens in the
workforce. To what extent do you think firms should
continue to keep the elderly on their payroll?
39. Introduces bias because it covers two issues at
once.
I am satisfied with my masters level performance.
My bachelors performance was also satisfying

40.
Use simple, interesting opening questions e.g asking for
respondent’s opinion on an issue.
Ask general questions before specific questions funnel
approach
Use filter questions with care.
Do you like ice-cream? If yes then move to Q2; if No move to Q5 (filter)
Finish asking questions on one topic before moving to
another.
41. •
Keep questionnaire short if possible, but not too short that
you sacrifice needed information
•
Do not over crowd questionnaire
•
Provide decent margin space
•
Use multiple- grid layout for questions with similar
responses
•
Use good quality print paper.
•
Use booklet form if possible
•
Carefully craft the questionnaire title:
1. Captures respondent’s interest.
2. Shows importance of the study.
3. Shows interesting nature of the study.
42.
Pretesting Process
◦ Seeks to determine whether respondents have any
difficulty understanding the questionnaire and whether
there are any ambiguous or biased questions.
Preliminary Tabulation
◦ A tabulation of the results of a pretest to help determine
whether the questionnaire will meet the objectives of the
research.
43.
Back Translation
◦ Taking a questionnaire that has previously been
translated into another language and having a second,
independent translator translate it back to the original
language.
◦ A questionnaire developed in one country may be difficult
to translate because equivalent language concepts do
not exist or because of differences in idiom and language
