Exam 11: Experimental Research: An Overview

In an experiment,the change in the ____________________ variable is presumed to be the cause of the results.

"Does package size affect consumption rates in snack products?" is a typical question in what type of research design?

One way to reduce demand characteristics is to tell subjects the purpose of the experiment so they will be more willing to participate honestly.

List the four important elements in experimental design.

Compare and contrast internal validity and external validity and discuss which one is most important in experimental research.

Monica is conducting an experiment where all subjects see all of the ads 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:

Between-subjects designs involve repeated measures because with each treatment the same subject is measured.

In an experiment,effects are the characteristics of experiments that allow hypotheses to be tested.

An experimental deception that involves a false treatment is called a(n)____________________.

The experimental difference in means between the different levels of any single experimental variable is referred to as a(n):

Factorial experimental designs are the least sophisticated type of experimental design.

Covariates are categorical variables like a subject's gender or ethnicity.

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.

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?

A researcher is conducting an experiment in which one group of people is exposed to an advertisement and another group is exposed to another advertisement.He is examining the effect of headline font sizes on consumers' attitude toward the brand advertised.The participants in this experimental research are referred to as:

All of the following are ways to reduce demand characteristics EXCEPT:

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:

Which of the following is the term used to refer to a treatment combination within an experiment?

When subjects in all experimental groups are exposed to identical conditions except for the differing experimental treatments,this is called:

When subjects in an experiment perform differently because they realize that they are participating in an experiment,this is called the ____________________ effect.
