Question 1

Gower's coefficient of similarity is capable of handling data that is

Accepted Answer

Gower's coefficient of similarity is a versatile measure that can handle various types of data, including dichotomous, multichotomous, interval, and ratio-scaled data, making it suitable for mixed data types.

Question 2

To determine the number of relevant clusters to retain when examining the plot of the number of clusters versus the fusion coefficient, the analyst should look for

Accepted Answer

The correct answers are significant savings in the fusion coefficient and points where the curve flattens out. These criteria are used to identify the "elbow" in the plot, which indicates the optimal number of clusters to retain. Significant savings in the fusion coefficient suggest a substantial reduction in within-cluster variance, and the point where the curve flattens indicates diminishing returns on adding more clusters.

Question 3

The following questions focus on Multidimensional Scaling:
-The basic objective in multidimensional scaling is to

Accepted Answer

The primary goal of multidimensional scaling (MDS) is to translate people's perceptions of the similarity between objects (or stimuli) and their preferences for these objects into a configuration within a multidimensional space. This allows for the visualization and analysis of the relationships between objects based on perceived similarities or preferences.

Question 4

The following questions focus on Multidimensional Scaling:
-The computer output of nonmetric multidimensional scaling analysis provides which of the following?

Accepted Answer

Nonmetric multidimensional scaling analysis provides both the number of dimensions underlying the respondent's judgments (A) and a map of the configuration characterizing the respondent's judgments (B), but it does not directly provide the attributes the individual is using when making judgments (C).

Question 5

The following questions focus on Multidimensional Scaling:
-Which of the following is FALSE?

Accepted Answer

Multidimensional scaling (MDS) is primarily associated with nonattribute-based approaches to creating perceptual maps, not attribute-based approaches. It focuses on the distances or dissimilarities between objects without relying on predefined attributes or characteristics.

Question 6

The following questions focus on Multidimensional Scaling:
-Which of the following is TRUE?

Accepted Answer

Multidimensional scaling is based on the concept of distance or proximity, which reflects psychological nearness between objects.

Question 7

The following questions focus on Multidimensional Scaling:
-Multidimensional scaling is concerned with

Accepted Answer

Multidimensional scaling is concerned with the mapping of perceptions and preferences.

Question 8

The following questions focus on Multidimensional Scaling:
-In multidimensional scaling, one of the major problems is naming the dimensions. The methods for doing this include

Accepted Answer

The correct methods for naming the dimensions in multidimensional scaling include computing the correlations between physical characteristics and the scores of the various dimensions of the configuration (A), and naming them based on the researcher's insight and experience (B). Locating the ideal points (C) and increasing the number of dimensions (D) are not methods used for naming the dimensions.

Question 9

The following questions focus on Multidimensional Scaling:
-Which of the following about perceptual maps is TRUE?

Accepted Answer

The answer of The following questions focus on Multidimensional Scaling:
-Which...

Question 10

The following questions focus on Multidimensional Scaling:
-Which of the following about multidimensional scaling is TRUE?

Accepted Answer

The answer of The following questions focus on Multidimensional Scaling:
-Which...

Question 11

The following questions focus on Multidimensional Scaling:
-Non-metric methods of multidimensional scaling generate

Accepted Answer

Non-metric methods of multidimensional scaling are designed to generate metric (quantitative) output from ordinal (rank order) input. This allows for the analysis and visualization of the distances or dissimilarities between items based on their rank order, rather than requiring precise numerical distances as input.

Question 12

The following questions focus on Multidimensional Scaling:
-Which of the following is FALSE?

Accepted Answer

Nonattribute-based approaches to the development of perceptual maps, such as those used in Multidimensional Scaling (MDS), often make it more difficult to name the dimensions because they emerge from the data rather than being predefined. This contrasts with attribute-based approaches where dimensions are based on specific attributes that are already named.

Question 13

The following questions focus on Multidimensional Scaling:
-Which of the following questions are typically NOT of concern once a respondent has ranked a group of objects according to similarity?

Accepted Answer

Multidimensional Scaling (MDS) focuses on understanding the dimensions underlying respondents' perceptions of similarity among objects, not the order in which objects were considered or ranked.

Question 14

The following questions focus on Multidimensional Scaling:
-Which of the following are not methods for naming underlying dimensions in multidimensional scaling?

Accepted Answer

The answer of The following questions focus on Multidimensional Scaling:
-Which...

Question 15

The following questions focus on Multidimensional Scaling:
-Kruskal's stress

Accepted Answer

Kruskal's stress is a lack of fit index used in Multidimensional Scaling (MDS) to assess how well the distances in a low-dimensional space represent the distances in the original high-dimensional space. A lower stress value indicates a better fit.

Question 16

The following questions focus on Multidimensional Scaling:
-Which of the following statements is FALSE?

Accepted Answer

Similarity measurement does not have the advantage over attribute ratings in multi-dimensional scaling analysis in that it better handles the problem of grouping respondents with similar perceptions.

Question 17

The following questions focus on Multidimensional Scaling:
-Which of the following is FALSE?

Accepted Answer

The answer of The following questions focus on Multidimensional Scaling:
-Which...

Question 18

The following questions focus on Multidimensional Scaling:
-Which of the following regarding the attribute-based versus the nonattribute based approaches to the development of perceptual maps is FALSE?

Accepted Answer

Computer programs for the attribute-based approaches are generally less expensive to run, making option E false.

Question 19

The following questions focus on Multidimensional Scaling:
-For which of the following applications would multidimensional scaling not be appropriate?

Accepted Answer

Multidimensional Scaling (MDS) is a statistical technique used for exploring similarities or dissimilarities in data. It is appropriate for all the applications listed: determining market segments, finding market opportunities, identifying preferred attributes, and determining perceived product attributes. These tasks involve understanding relationships and perceptions in data, which MDS is well-suited to analyze.

Question 20

The following questions focus on Multidimensional Scaling:
-The dimensions that appear in the perceptual map generated by multidimensional scaling procedures are determined by

Accepted Answer

The dimensions in a perceptual map generated by multidimensional scaling are determined by the stimulus set, as the analysis seeks to represent the distances or dissimilarities between items (stimuli) in a low-dimensional space.
