instrumentation effect
Differences in dependent variable means due to a specific combination of independent variables are called _____ effects.
interaction
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?
interaction
The question as to whether the independent variable was the sole cause of the change in the dependent variable is the basic issue in _____.
internal validity
What is the key advantage of test-marketing?
it is performed in a real-world setting
In which type of experiment does the research have more complete control over the research setting and extraneous variables?
laboratory
When an experiment is conducted on the premises of a marketing research organization, this is an example of a _____.
laboratory experiment
The experimental difference in means between the different levels of any single experimental variable is referred to as a(n) _____.
main effect
When subjects in an experiment in which the they were exposed to varying price levels for a product are asked how low they believe the price of the product to be so that the researcher can determine whether or not the subjects perceived "high" and "low" conditions, this is an example of a _____.
manipulation check
All of the following are experimental design issues EXCEPT _____.
manipulation of the dependent variable
Which of the following is a function of time and the naturally occurring events that coincide with growth and experience?
maturation effect
The sampling units in experiments are referred to as ____.
subjects
A psychology professor is conducting an experiment in which subjects perform memory tasks. There are four groups, each participating in different buildings on campus. During the time of the experiment one group was in a building near a dumpster that was being emptied by a big, noisy trash truck. The other groups weren't close enough to hear the noise. Which type of error does this introduce into the research?
systematic error
When high school students who take the ACT in their junior year perform better on that exam during their senior year because they know better how to take the exam because of what they experienced on the first exam, this is an example of a _____.
testing effect
Which experimental research design involves repeated measures?
within-subjects design
What is the difference between a blocking variable and a covariate?
Blocking variables are categorical variables and covariates are continuous variables.
Experiments are widely used in which type of research designs?
causal
A marketing researcher is manipulating exposing subjects to one of two price levels--$1.99 or $2.49--for a tube of chapstick and measures behavioral intentions. The two price levels are known as experimental_____ in the study.
conditions
When a competitor introduces a 15 percent price cut in order to blunt the effect of a test marketing study, this is an example of a _____.
history effect
When salespeople are tested one year after a sales training program and perform better on the exam, not because of the training program, but because they have gained one year's experience in sales, this is an example of a _____.
maturation effect
When some subjects exit the experiment before it is completed and this effects the results of the study, this is an example of a _____.
mortality effect
A device that controls the amount of time a subject is exposed to a visual image is called a _____.
tachistoscope
The way an experimental variable is manipulated is referred to as an experimental _____.
treatment
If the level of advertising expenditures is compared to the number of units sold at the end of a four-month period, the independent variable is ______ while the dependent variable is ______.
advertising expenditure level; units sold
Which term refers to an experimental design element that unintentionally provides subjects with hints about the research hypothesis.
demand characteristic
Which type of effect occurs when a change other than the experimental treatment occurs during the course of an experiment that affects the dependent variable?
history effect
Which type of effect occurs when there is a change in the wording of questions, a change in interviewers, or a change in other procedures that causes a change in the dependent variable?
instrumentation effect
Which of the following occurs if the sampling units in an experimental cell are somehow different than the units in another cell, and this difference affects the dependent variable?
systematic or nonsampling error
_____ are the subjects or entities whose responses to the experimental treatment are measured.
Test units
An experiment is conducted in which music played in a store is manipulated to examine the impact on sales. What type of experimental design is this?
basic experimental design
Which experimental design involves manipulating a single independent variable to observe its effect on a single dependent variable?
basic experimental design
In which experimental research design does each subject receive only one treatment combination?
between-subjects design
