d
Experimental results that show that consumers purchased more when a store had a blue color with bright lights than they did when a store was orange with bright lights but no difference when the lighting was low is an example of which type of effect? a. main b. interaction c. confound d. synergistic
B
Monica is conducting an experiment where all subjects rotate through all of the training programs she is testing. This type of experiment in which an individual subject is exposed to more than one level of an experimental treatment is called: a. between-subjects b. repeated measures c. redundant manipulation d. randomization
B
The experimental difference in means between the different levels of any single experimental variable is referred to as a(n): a. interaction effect b. primary effect c. main effect d. confound
C
Which of the following is the term used to refer to a treatment combination within an experiment? a. level b. link c. cell d. unit
C
A confound in an experiment means that there is an alternative explanation beyond the experimental variables for any observed differences in the dependent variable
T
Categorical variables like a subject's gender or ethnicity are known as which type of variable in experimental research? a. blocking variables b. covariates c. main variables d. confounds
A
When a researcher tries to say that the results of a test market in Indianapolis, Indiana will hold in a national rollout of the new product, this researcher is concerned with: a. internal validity b. the repeated measures effect c. constant error d. external validity
D
Which of the following are possible test units in a business research study? a. people b. sales territories c. strategic business units d. all of the above
D
3. Participants in experimental research are typically referred to as respondents.
F Participants in experimental research are referred to as subjects rather than respondents
When a test market is conducted in five retail stores in Erie, Pennsylvania, this is an example of a laboratory experiment
F Field Experiment
17. The people administering an experiment must be aware of the experimental hypotheses.
F could be double blind
An experimental construct refers to one of the possible levels of an experimental variable manipulation.
F experimental conidtion
One way to reduce demand characteristics is to tell subjects the purpose of the experiment so they will be more willing to participate honestly.
F implement experiment disguise
The question as to whether the experimental treatment was the "sole cause" of the changes in the dependent variable is the basic issue in external validity
