Question 1

The test statistic used to test the hypothesis of whether a regression coefficient is significantly different from zero, holding all other independent variables constant, is called a(n):
A)F-test.
B)autocorrelation test.
C)multicollinearity test.
D)t-test.

Accepted Answer

The test statistic used to test the hypothesis of whether a regression coefficient is significantly different from zero, holding all other independent variables constant, is a t-test. The F-test is used to test the overall significance of the regression model, the autocorrelation test is used to test for correlation among residuals, and the multicollinearity test is used to test for multicollinearity among independent variables. Therefore, the best choice is D, the t-test.

Question 2

The ratio of the regression coefficient to its standard error is called:
A)t-statistic.
B)F-statistic.
C)partial F-statistic.
D)coefficient of determination.

Accepted Answer

The ratio of the regression coefficient to its standard error is called the t-statistic. This statistic is used to test the hypothesis that the regression coefficient is zero, which is equivalent to saying that there is no relationship between the independent variable and the dependent variable.

Question 3

A measure of how much the coefficient would vary in regressions based on different samples is called:
A)standard error of the estimated coefficient.
B)F-statistic.
C)partial F-statistic.
D)t-statistic.

Accepted Answer

The standard error of the estimated coefficient measures the variability of the coefficient across different samples. This is an important metric for understanding the precision of the coefficient estimate and for performing hypothesis testing using the t-statistic. The F-statistic and partial F-statistic are used for different purposes, and the t-statistic is closely related to the standard error but does not measure the variability of the coefficient across different samples.

Question 4

The number of observations minus the number of estimated coefficients in a regression equation is called:
A)degrees of freedom.
B)variance.
C)standard error fo the regression.
D)none of the above.

Accepted Answer

The number of observations minus the number of estimated coefficients in a regression equation gives us the degrees of freedom, which is an important concept in hypothesis testing and calculating statistical significance. Therefore, choice A is the correct answer. Choices B and C are incorrect, as they do not relate to the given formula. Choice D is also incorrect as there is a correct answer in the options.

Question 5

Cross-sectional data observed at several points in time is known as:
A)time series data.
B)panel data.
C)experimental data.
D)none of the above.

Accepted Answer

Cross-sectional data observed at several points in time is known as panel data. Time series data refers to observations of a single variable over time, while experimental data involves manipulating variables in a controlled setting. None of these options accurately describes cross-sectional data observed at multiple points in time. Therefore, the correct answer is B.

Question 6

A)simple regression analysis.
B)correlation analysis.
C)multiple regression analysis.
D)cluster analysis.

Accepted Answer

Multiple regression analysis is used when there is more than one independent variable that may be influencing the dependent variable. Simple regression analysis only has one independent variable, while correlation analysis only looks at the strength and direction of the relationship between two variables. Cluster analysis is a technique used to group similar objects or variables into clusters or groups.

Question 8

The approach to analyzing consumer behavior that asks consumers to rank and choose among different product attributes to reveal their relative valuation of different characteristics is called:
A)a direct consumer survey.
B)contingent valuation.
C)the hedonic estimation technique.
D)conjoint analysis.

Accepted Answer

Conjoint analysis is a popular approach used in marketing research to understand consumer preferences and to determine how they react or respond to different product features.The approach requires consumers to rank and choose among different product attributes to reveal their relative valuation of different characteristics. With this information, marketers can prioritize product attributes and create products that better meet the needs of their target audience.

Question 9

Data collected on the same observation unit at a number of points in time are called:
A)cross-section data.
B)time series data.
C)panel data.

Question 10

The least squares regression is based on:
A)maximizing the absolute sum of squares errors.
B)minimizing the absolute sum of squares errors.
C)maximizing the sum of squared errors.
D)minimizing the sum of squared errors.

Accepted Answer

The least squares regression technique aims to minimize the sum of squared errors between the predicted values and the actual values. This method leads to the best fit line for the given data set. Therefore, the correct choice is D, i.e., minimizing the sum of squared errors.

Question 11

Which of the following approaches to understanding and predicting consumer behavior does not actually solicit any information from any potential customers?
A)Test marketing.
B)Conjoint analysis.
C)Analysis of historical data.
D)Expert opinion.

Accepted Answer

Analysis of historical data does not directly solicit information from potential customers. It involves analyzing past purchase behavior and external factors that may have influenced it, in order to identify patterns and make predictions about future behavior. The other options all involve soliciting information from potential customers in some way. Test marketing involves putting a product in a selected market to observe and gather feedback on consumer behavior. Conjoint analysis uses surveys or experiments to determine how consumers prioritize different product attributes. Expert opinion involves gathering insights from professionals with specialized knowledge and experience in the industry.

Question 12

An approach to analyzing consumer behavior in which consumer reaction to different prices is analyzed in a laboratory situation or a test market is called:
A)price experiments.
B)non-price experiments.
C)focus groups.
D)none of the above.

Accepted Answer

Price experiments involve setting different prices for a product and analyzing how consumers react to each price. This can be done in a laboratory setting or a test market. Non-price experiments involve analyzing consumer behavior in response to other marketing variables, such as advertising or packaging. Focus groups involve gathering a small group of consumers to discuss their opinions and behaviors related to a product or service. Therefore, the best choice for this question is A, as it specifically refers to analyzing consumer reaction to different prices.

Question 13

Data collected on a sample of individuals with different characteristics at a specific point in time are called:
A)cross-section data.
B)time series data.
C)panel data.
D)none of the above.

Accepted Answer

Cross-section data are collected at a specific point in time on a sample of individuals with different characteristics, while time series data are collected over a period of time on the same individuals or units, and panel data are a combination of both cross-section and time series data collected on the same individuals or units over time. Therefore, option A is the best choice for the given question.

Question 14

Which of the following approaches to understanding and predicting consumer behavior provides the most insight into how consumers can be expected to respond in an actual market setting?
A)Test marketing.
B)Conjoint analysis.
C)Analysis of historical data.
D)Expert opinion.

Accepted Answer

Test marketing involves testing a product or marketing strategy in a real-life market setting. This approach provides the most accurate and realistic understanding of consumer behavior as it directly observes how consumers respond to a product or marketing strategy in a real market environment. Conjoint analysis, analysis of historical data, and expert opinion can provide valuable insights but may not accurately predict actual consumer response in a market setting.

Question 15

All of the following are limitations of direct consumer surveys except:
A)the possibility that consumers' responses may not reflect their actual behavior in the market place.
B)the possibility of response biases because survey respondents may not want to reveal their true preferences.
C)the likelihood that respondents will deliberately and systematically mislead interviewers.
D)the possibility that the type of questions asked may unintentionally bias the respondent's answers.

Accepted Answer

C is not a limitation of direct consumer surveys; it is an assumption that should be avoided when conducting surveys. Limitations of direct consumer surveys include response biases, unintentional bias in the questions asked, and the possibility that consumer survey responses may not reflect their actual behavior in the market place.

Question 16

Regressional analysis that analyzes the relationship between one dependent variable and one independent variable is called:
A)simple regression analysis.
B)correlation analysis
C)multiple regression analysis.
D)cluster analysis.

Accepted Answer

Simple regression analysis analyzes the relationship between one dependent variable and one independent variable. Correlation analysis simply measures the strength of the relationship between two variables, but does not determine causation. Multiple regression analysis analyzes the relationship between one dependent variable and multiple independent variables. Cluster analysis is a type of exploratory data analysis used to identify groups of similar data points.

A)Direct consumer surveys.
B)Expert opinion.
C)Analysis of historical data.
D)Test marketing and price experiments.

Accepted Answer

Expert opinion relies on the expertise and experience of a firm's employees and suppliers to predict consumer behavior, rather than gathering direct consumer feedback or analyzing historical data. Therefore, B is the correct answer.

Question 19

The coefficient of determination is defined as the:
A)ratio of the total sum of squared errors to the sum of squared errors.
B)ratio of the regression sum of squares to the sum of the squared errors.
C)ratio of the sum of squared errors to the total sum of squared errors.

Question 20

Which of the following statements is correct?
A)The use of Census data is especially useful and cost-effective in targeted marketing.
B)Census data are considered more reliable than data collected via direct consumer surveys because people are more likely to provide accurate responses to government census takers.
C)While the use of census data in targeting marketing can provide relatively accurate information, experience has shown that it has the disadvantage of increasing marketing costs by a substantial amount.
D)While census data are considerably less expensive than data obtained via direct consumer surveys, they are also considerably less reliable.

Accepted Answer

The statement "The use of Census data is especially useful and cost-effective in targeted marketing" is correct because Census data provide detailed demographic information about a given population, including age, gender, income, education levels, and more, making it easier for marketers to identify and target specific groups of consumers who are more likely to be interested in their products or services. Additionally, Census data are freely available and can be obtained easily through the U.S. Census Bureau website, making them a cost-effective source of information for marketers.
