Exam 15: Data Analysis: Basic Questions

(Use the following information for the next two questions.) The manager of a car dealership was concerned that female customers found sales representatives to be intimidating. The manager asked a local market research firm to determine whether or not significant gender based differences existed in attitudes toward automobile sales personnel. The research supplier used random digit dialing to contact 200 men and women over the age of 21 in the dealer's market area. Respondents were asked to rate automobile salespeople in the local area on helpfulness, willingness to deal, answering questions fully, courtesy, and patience using a 7-point Likert scale with 1 being poor to 7 being excellent. All respondents were also asked if new car salespeople were intimidating (yes or no). Only one person per household was asked to respond to the survey and the variances between the two groups on all questions were assumed to be equal. -Given this design, which of the following statements would be legitimate conclusions based on the scales being used?

Which of the following is false?

(Use the following information for the next two questions.) Consider the following advertising claims: Claim 1: "Ultrasoft chairs last 50% longer than our competitor's best chairs." Claim 2: "A random sample of homemakers found Ultrasoft chairs 65% more comfortable than our leading competitor's chairs." -Which of the these claims can likely be made legitimately?

Which of the following is true?

A research design diagrammed as: 0₁ X 0₂ suggests

The scale skilled, semi-skilled, and unskilled laborer was used to classify respondents in a recent survey. The appropriate measure(s) of central tendency for this variable are

A large consumer products company wants to increase sales of an existing laundry detergent product. The brand team can not decide whether to use a newspaper coupon (X₁), a sample drop (X₂), or an in-store coupon (X₃) to increase sales. The research manager suggests an in-market test to (1) determine if any of the promotions had an impact, and (2) which had the greater impact. Of the designs shown below, which would provide the research manager with the information necessary to make this determination?

(Use the following information for the next two questions.) Consider the following advertising claims: Claim 1: "Ultrasoft chairs last 50% longer than our competitor's best chairs." Claim 2: "A random sample of homemakers found Ultrasoft chairs 65% more comfortable than our leading competitor's chairs." -Which of the following statements is true with regard to Claim 2?

The appropriate analysis technique does NOT depend on

Which of the following is FALSE?

(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?

Which of the following is a means of looking at differences among groups when a number of characteristics are considered simultaneously?

The parametric statistical procedures are appropriate if the data is

In the following statement which claim is probably correct, given each claim was established using rating scales completed by consumers? "New improved Killo disinfectant now has a 50% fresher odor, is 15% less irritating, is 25% easier to use, and in a selected sample was stated as being more effective by 50% of the subjects."

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

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
