Exam 7: Casual 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.

Using the set of symbols commonly used in marketing research to denote experimental designs,which symbol below represents the exposure of a group to an independent variable,treatment,or event the effects of which are to be determined?

If the experimental design called for the respondents to be randomly assigned to one of three experimental groups and for one of three versions of a test commercial to be randomly administered to each group,this design would be using ________.

Standard text markets can cost as much as $1 million;simulated test markets cost less than 10 percent as much.

An experiment is formed when the researcher manipulates one or more dependent variables and measures their effect on one or more independent variables,while controlling for the effect of extraneous variables.

If the goal of the researcher is to make valid generalizations to a larger population of interest,then,the researcher is concerned with internal validity.

Which statement is not true about why it is difficult to conduct field experiments in the international arena?

The statement 'An effect cannot be produced by an event that occurs after the effect has taken place,' refers to ________.

________ allow for the statistical control and analysis of external variables.

________ means that the factor or variable being investigated should be the only possible causal explanation.

History (H)refers to the occurrence of events before the experiment.

All of the following statements are true about external validity except ________.

Extraneous variables are all variables other than the independent variables that affect the response of the test units.

Discuss the trade-offs that must be made in experimental design formulation when trying to obtain realistic amounts of internal and external validity.
