3Measurement and Scaling
- Scaling involves creating a continuum upon which
measured objects are located. - Measurement is the actual assignment of a number
from 1 to 100 to each respondent. Scaling is the
process of placing the respondents on a continuum
with respect to their attitude toward department
stores.

appropriate category.) Will definitely not

10Comparative Scaling TechniquesPaired Comparison
Scaling
- A respondent is presented with two objects and
asked to select one according to some criterion. - Paired comparison scaling is the most widely used
comparative scaling technique. - With n brands, n(n - 1) /2 paired comparisons
are required

18Continuous Rating Scale
- Respondents rate the objects by placing a mark at
the appropriate position - on a line that runs from one extreme of the
criterion variable to the other. - The form of the continuous scale may vary
considerably. -
- How would you rate Sears as a department store?
- Version 1
- Probably the worst - - - - - - -I - - - - - - - -

- Version 3
- Very bad Neither good Very
good - nor bad
- Probably the worst - - - - - - -I - - - - - - - -

- - - - - -Probably the best - 0 10 20 30 40 50 60 70 80 90 100
19An Itemized Rating Scale - Likert Scale
- The Likert scale requires the respondents to
indicate a degree of agreement or - disagreement with each of a series of statements
about the stimulus objects. -
- Strongly Disagree Neither Agree Strongly
- disagree agree nor agree
- disagree
-
- 1. Sears sells high quality merchandise.
1 2X 3 4 5 -
- 2. Sears has poor in-store service.
1 2X 3 4 5 -
- 3. I like to shop at Sears. 1 2 3X 4 5
-
- The analysis can be conducted on an item-by-item
basis (profile analysis), or a total (summated)
score can be calculated. - When arriving at a total score, the categories
assigned to the negative statements by the
respondents should be scored by reversing the
scale.

21Stapel Scale
- The Stapel scale is a unipolar rating scale with
ten categories - numbered from -5 to 5, without a neutral point
(zero). This scale - is usually presented vertically.

27Measurement Accuracy
- The true score model provides a framework for
understanding the accuracy of measurement. -
- XO XT XS XR
-
- where
- XO the observed score or measurement
- XT the true score of the characteristic
- XS systematic error
- XR random error
28Measurement Accuracy
- Xo XT XS XR
- Xo 7.5
- XT 7.0 - true score for liking the Hershey
Chocolate Bar - XS -.5 Hershey Bar is smaller than
competitors bar in the SW - XR 1.0 Respondent received one as gift last
week
29Reliability
- Represents the scales ability to give stable
measures regardless of time and conditions - Has nothing to do with being right - (think of a
rifle that consistently shoots high and right) - internal consistency reliability - frequently
used - Cronbachs alpha (a) - interval and ratio data
- Kuder-Richardson (KR-20) - nominal and ordinal
30Increasing Reliability - KISS
- Ask people things they know, not things theyll
guess at. - Ask people things theyll tell us, not things
theyll lie about. - Ask people questions they can understand easily
and answer accurately. - Use multiple-choice questions and short surveys.
- Ask about easy, straightforward issues.
31Validity
- The validity of a scale is the extent to which it
is a true reflection of the underlying variable
it is attempting to measure
32Validity
- Are we measuring what we set out to measure?
- Example
- We want to know if our motorcycle will be
purchased. - We ask those seeking a motorcycle if they like
it. - We have NOT measured purchase intention. We have
measured attitude toward our motorcycle.
33Increasing Validity
- Ask respondents to answer in great detail.
- Ask questions fully, so there is no ambiguity.
- Use a reliable instrument.
- Ask questions on related areas to get the big
picture. - Ask lots of questions to be sure you cover the
subject completely.
