Accepted Answer

A) once 
B) twice 
C) not at all

Question 5

A ________ design to measure the effectiveness of a test commercial for Sears would be implemented as follows.Two groups of respondents would be recruited on the basis of convenience.Only the experimental group would be exposed to the TV program containing the test (Sears)commercial.Then attitudes toward the department store of both the experimental and control group respondents would be measured.The effectiveness of the test commercial is measured as O1 - O2.

Accepted Answer

A) one-shot case study 
B) pretest-posttest control group 
C) static group 
D) one-group pretest-posttest

Question 6

The one-group pretest-posttest is a type of ________.These designs do not control for extraneous factors by randomization.

Accepted Answer

A) quasi-experimental design 
B) true experimental design 
C) statistical design 
D) preexperimental design

Question 7

Which of the following statements is a limitation of Latin square designs?

Accepted Answer

A) They require an equal number of rows,columns,and treatment levels,which is sometimes problematic. 
B) They do not allow the researcher to examine interactions of the external variables with each other or with the independent variable. 
C) The researcher can control for only one external variable. 
D) Both A and B are correct.

Question 8

Using the set of symbols commonly used in marketing research to denote experimental designs,which symbol below represents the process of observation or measurement of the dependent variable on the test units or group of units?

Accepted Answer

A) T 
B) O 
C) R 
D) X

Question 9

Which statement is not true concerning a standard test market?

Accepted Answer

A) It is a one-shot case study. 
B) Test markets are selected and the product is sold through regular distribution channels. 
C) Where external validity is important,at least four test markets should be used. 
D) All statements are correct.

Question 10

Which of the following is a reason why experiments may be hard to administer?

Accepted Answer

A) It may be impossible to control for the effects of the extraneous variables. 
B) Competitors may deliberately contaminate the results of a field experiment. 
C) Both A and B are reasons why experiments may be hard to administer. 
D) Neither A nor B is a reason why experiments may be hard to administer.

Question 11

Full experimental control is available in quasi-experimental designs;therefore,the researcher does not need to take into account the specific variables that are not controlled.

Accepted Answer

A) True 
 B)False

Question 12

Descriptive survey studies do not meet all conditions required for causality.

Accepted Answer

A) True 
 B)False

Question 13

Which experimental design means that two groups of test units were randomly assigned to two different treatment groups at the same time,and the dependent variable was measured in the two groups simultaneously?

Accepted Answer

A) R X1 O1 R X2 O2 
B) R X1 O1 O2 X2 O2 
C) X O1 O2 X O1 O2 
D) R X1 O1 R X1 O1

Question 14

Experimental designs may be classified as preexperimental,true experimental,quasi-experimental,or statistical.

Accepted Answer

A) True 
 B)False

Question 15

In practice,a control group is sometimes defined as the group that receives the current level of marketing activity,rather than a group that receives no treatment at all because it is difficult to reduce current marketing activities,such as advertising and personal selling,to zero.

Accepted Answer

A) True 
 B)False

Question 16

________ involves measuring the extraneous variables and adjusting for their effects through statistical analysis.

Accepted Answer

A) Design control 
B) Statistical control 
C) Randomization 
D) Matching
