Exam 7: Causal Research Design: Experimentation

Matching is a method of controlling extraneous variables that involve matching test units on a set of key background variables before assigning them to the treatment conditions.

What is the difference between a times series design and a multiple times series design?

The one-group pretest-posttest design may be symbolized as O₁ X₂ O_2. In this design,a group of test units is measured ________.

The longer the time interval between observations,the greater the possibility that history will confound an experiment.

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.

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

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

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?

Which statement is not true concerning a standard test market?

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

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.

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

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?

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

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.

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