Description

Chapter 8 Measurement and Scaling: Fundamentals and Comparative Scaling True/False Questions 1. When we measure the perceptions, attitudes, and preferences of consumers, we are measuring the objects of other relevant characteristics. (False, difficult, page 236) 2. In measurement, when assigning numbers to the characteristics there must be a oneto-one correspondence between the numbers and the characteristics being measured. (True, moderate, page 236) 3. There are three primary scales of measurement: nominal, ordinal, and ratio. (False, easy, page 236) 4. A nominal scale can only involve the assignment of numbers; alphabets or symbols cannot be assigned. (False, easy, page 237) 5. Only a limited number of statistics, all of which are based on frequency counts, are permissible on the numbers in a nominal scale. (True, moderate, page 238) 6. An ordinal scale indicates relative position and the magnitude of the differences between the objects. (False, easy, page 238) 7. In addition to the counting operation allowable for nominal scale data, ordinal scales permit the use of statistics based on percentiles. (True, moderate, page 239) 8. Ratios of differences between scale values are permissible. (True, easy, page 240) 9. Statistical techniques that may be used on interval scale data include all of those that can be applied to nominal, ordinal, and ratio data.

(False, easy, page 240) 10. Ratio scales allow proportionate transformations of the form y = b x, where b is a positive constant. One can add an arbitrary constant, as in the case of an interval scale. (False, moderate, page 241) 11. All statistical techniques can be applied to ratio data. (True, easy, page 241) 12. It is possible to construct a nominal scale that provides partial information on order (the partially ordered scale). (True, moderate, page 241) 13. Comparative scales involve the direct comparison of stimulus objects. (True, easy, page 241) 14. In non-comparative scales, the scaling of each object is dependent on the others in the stimulus set. (False, moderate, page 242) 15. Non-comparative scales data are generally assumed to be interval or ratio scaled. (True, moderate, page 242) 16. In paired comparison scaling, the data obtained are interval in nature. (False, moderate, page 242) 17. Transitivity of preference is an assumption made in order to convert constant sum data to rank order data. It implies that if brand A is preferred to brand B and brand B is preferred to brand C, then brand A is preferred to brand C. (False, moderate, page 243) 18. Paired comparisons bear little resemblance to the marketplace situation that involves selection from multiple alternatives. (True, easy, page 243) 19. Paired comparison scaling is useful when the number of brands is large, because it requires direct comparison and overt choice.

(True, moderate, page 243) 20. Rank order scaling is commonly used to measure preferences for brands as well as attributes. (True, moderate, page 244) 21. In constant sum scaling, if an attribute is twice as important as some other attribute, it receives twice as many points. (True, moderate, page 246) 22. Constant sum scale data are sometimes treated as metric. (True, difficult, page 247) 23. The constant sum should be considered an ordinal scale. (True, difficult, page 247) 24. From the viewpoint of the respondents, ratio scales are the simplest to use, whereas the nominal scales are the most complex. (False, easy, page 247) 25. It is the obligation of the researcher to obtain data that are most appropriate, given the research questions to be answered. (True, easy, page 248) 26. All the primary scales of measurement explained in the text can be implemented on the Internet. (True, moderate, page 249) 27. It may be difficult to implement specialized scales such as the Q-sort on the Internet.

Essay Questions 66. Discuss the primary scales of measurement (Table 8.1). Develop an example of each. Answer A nominal scale is one whose numbers serve only as labels or tags for identifying and classifying objects with a strict one-to-one correspondence between the numbers and the objects. For example, the numbers assigned to the respondents in a study constitute a nominal scale. An ordinal scale is a ranking scale in which numbers are assigned to objects to indicate the relative extent to which the objects possess some characteristic. An ordinal scale allows you to determine whether an object has more or less of a characteristic than some other object, but not how much more or less. Thus an ordinal scale indicates relative position, not the magnitude of the differences between the objects. Common examples of ordinal scales include quality rankings, rankings of teams in a tournament, socioeconomic class, and occupational status. In an interval scale, numerically equal distances on the scale represent equal values in the characteristic being measured. An interval scale contains all the information of an ordinal scale, but it also allows you to compare the differences between objects. A common example in everyday life is a temperature scale. In marketing research, attitudinal data obtained from rating scales are often treated as interval data. A ratio scale possesses all the properties of the nominal, ordinal, and interval scales and, in addition, an absolute zero point. Thus, in ratio scales we can identify or classify objects, rank the objects, and compare intervals or differences. Common examples of ratio scales include height, weight, age, and money. In marketing, sales, costs, market share, and number of customers are variables measured on a ratio scale. (moderate, pages 236-239, 241) 67. Compare the rank order scaling technique to the paired comparison scaling technique. Answer After paired comparisons, the most popular comparative scaling technique is rank order scaling. In rank order scaling , respondents are presented with several objects simultaneously and asked to order or rank them according to some criterion. In paired comparison scaling, a respondent is presented with two objects and asked to select one according to some criterion. Like paired comparison, rank order scaling is also comparative in nature and it is possible that the respondent may dislike the brand ranked 1 in an absolute sense. As compared to paired comparisons, the rank order scaling process more closely resembles the shopping environment. It also takes less time and eliminates intransitive responses. If there are n stimulus objects, only (n - 1) scaling decisions need be made in rank order scaling. However, in paired comparison scaling [n(n - 1)/2] decisions would be required. Another advantage is that most respondents easily understand the instructions for ranking. The major disadvantage is 114

that this technique produces only ordinal data. Finally, under the assumption of transitivity, rank order data can be converted to equivalent paired comparison data, and vice versa. (difficult, pages 242, 244-245) 68. Why is there confusion over whether constant sum data are ordinal or metric? Answer The constant sum has an absolute zero—10 points are twice as many as 5 points, and the difference between 5 and 2 points is the same as the difference between 57 and 54 points. For this reason, constant sum scale data are sometimes treated as metric. Although this may be appropriate in the limited context of the stimuli scaled, these results are not generalizable to other stimuli not included in the study. Hence, strictly speaking, the constant sum should be considered an ordinal scale because of its comparative nature and the resulting lack of generalizability. (moderate, page 247)
