Question 1

When no variable is singled out for special treatment as a criterion variable but rather the researcher is interested in the relationship among all the variables considered at once, the most appropriate technique is
A) factor analysis.
B) multiple regression analysis.
C) linear discriminant analysis.
D) multiple regression with dummy variables.
E) multiple discriminant analysis.

Accepted Answer

Factor analysis is used when the interest is in understanding the relationships among several variables without designating any as dependent or independent. It helps in identifying underlying factors that explain the patterns of correlations among the variables.

Question 2

When a researcher is concerned with the relationship of a set of variables among themselves he is concerned with the analysis of
A) dependence.
B) interdependence.
C) independence.
D) predictor variables.
E) consequent variables.

Accepted Answer

Interdependence analysis is concerned with understanding how variables relate to each other without necessarily establishing a cause-and-effect relationship. It examines the structure of relationships among multiple variables simultaneously.

Question 3

When we are interested in examining the differences between two groups when a number of characteristics are simultaneously considered the most appropriate statistical technique is
A) univariate analysis.
B) multiple regression analysis.
C) multivariate test of group differences.
D) T-test for difference in two means.
E) traditional analysis-of-variance procedures.

Accepted Answer

Multivariate test of group differences is designed to examine the differences between groups across multiple variables simultaneously, making it the most appropriate choice for analyzing differences between two groups when considering several characteristics at once.

Question 4

(Use the following information for the next three questions.)
Consider the following scenarios:
SCENARIO A: The research director for a large chain of department stores is interested in examining the sales of a certain product in a sample of stores located on the west coast with sales of the product in a sample of stores located along the east coast in order to determine any differences in sales patterns.
 SCENARIO B: The product manager for a large ice cream company believes that sales of his product in supermarkets greatly depends upon the amount of space given to the product in the ice cream section and the amount of in store promotion given his product. To determine if this is the case, the manager collected data from 20 supermarkets.
-For which of these scenarios is univariate analysis appropriate?
A) Scenario A
B) Scenario B
C) both Scenario A and Scenario B
D) neither Scenario A nor Scenario B
E) more information is needed

Question 5

(Use the following information for the next three questions.)
Consider the following scenarios:
SCENARIO A: The research director for a large chain of department stores is interested in examining the sales of a certain product in a sample of stores located on the west coast with sales of the product in a sample of stores located along the east coast in order to determine any differences in sales patterns.
 SCENARIO B: The product manager for a large ice cream company believes that sales of his product in supermarkets greatly depends upon the amount of space given to the product in the ice cream section and the amount of in store promotion given his product. To determine if this is the case, the manager collected data from 20 supermarkets.
-Which of the following statistical procedures is NOT appropriate for use with Scenario A?
A) T-test
B) analysis of variance
C) Z-test
D) all of the above would be appropriate
E) none of the above would be appropriate.

Accepted Answer

Analysis of variance (ANOVA) is typically used when comparing more than two groups, whereas Scenario A involves comparing sales between two groups (west coast and east coast stores), making a t-test or z-test more appropriate.

Question 6

(Use the following information for the next three questions.)
Consider the following scenarios:
SCENARIO A: The research director for a large chain of department stores is interested in examining the sales of a certain product in a sample of stores located on the west coast with sales of the product in a sample of stores located along the east coast in order to determine any differences in sales patterns.
 SCENARIO B: The product manager for a large ice cream company believes that sales of his product in supermarkets greatly depends upon the amount of space given to the product in the ice cream section and the amount of in store promotion given his product. To determine if this is the case, the manager collected data from 20 supermarkets.
-Which of the following statistical procedures is appropriate for use with Scenario B?
A) factor analysis
B) discriminant analysis
C) multiple regression analysis
D) Spearman's Rank Correlation
E) all of the above are appropriate

Accepted Answer

Multiple regression analysis is appropriate for Scenario B because it allows the examination of the relationship between a dependent variable (sales of the ice cream) and multiple independent variables (amount of space given to the product and the amount of in-store promotion).
