External validity

A confound is an experimental deception involving a false treatment.

False

When subjects guess the purpose of an experiment, this creates a confound known as a bias effect.

When Procter & Gamble test markets a new shampoo to consumers in Kansas City and St. Louis, the consumers are participating in a(n) _________________ experiment.

Field

Research projects involving experimental manipulations that are implemented in a natural environment are called _______________.

Field experiments

An experiment can have only one independent variable.

Flase

A confound in an experiment means that there is an alternative explanation beyond the experimental variables for any observed differences in the dependent variable.

True

A maturation effect is a function of time and the naturally occurring events that coincide with growth and experience.

True

Experimental treatment refers to the way an experimental variable is manipulated.

True

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

True

In experimental research, the independent variable is manipulated rather than simply measured.

True

People are the most common test units for most marketing experiments.

True

Random assignment of subjects to treatment and control groups helps ensure that experimental and control groups do not differ from each other in important ways at the beginning of a research study.

True

Demand characteristics can be reduced in a number of ways. Which strategy below is NOT one of these?

Administer multiple experimental treatment levels to each subject

In a certain study, different interviewers are used in a pretest from those used in the posttest and this produces different results in the study. This is an example of a(n) ______________.

Instrumentation effect

Experimental results that show that consumers purchased more when a store had bright blue lights than they did when the store had bright orange lights. However, when the lighting was low, there was no difference between blue and orange lights. This illustrates a(n) _________.

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

All of the following are experimental design elements EXCEPT for the _____________.

Manipulation of the dependent variable

Which term means that subjects in all experimental groups are exposed to identical conditions except for the differing experimental treatments?

Constancy of conditions

In an experiment, the _________________ group does not receive the experimental treatment.

Control

A continuous variable that is expected to show a statistical relationship with the dependent variables is called a(n) _____________.

Covariate

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

Independent

In an experiment, the ___________________ variable is manipulated and its effect is measured on the ___________________ variable.

Independent; Dependent

The test of an experimental manipulation to intended make sure that the manipulation does produce desired differences in the independent variable is called a _______________.

Manipulation check

A researcher can equally distribute the effects of extraneous variables to all conditions in an experiment by using ____________.

Randomization

________________ is intended to equally distribute the effects of extraneous variables to all conditions.

Randomization

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. Which type of effect has occurred?

Maturation effect

Which type of effect is a function of time and the naturally occurring events that coincide with growth and experience?

Maturation effect

When a test market is conducted in five retail stores in Erie, Pennsylvania, a laboratory experiment has been performed.

False

When some subjects stop participating in an experiment before it is completed, affecting the results of the study, a(n) ______________ effect has occurred.

Mortality

Which experimental research design involves repeated measures?

Within-subjects design

The term linkage refers to a specific treatment combination associated with an experimental group.

False

In which experimental research design does each subject receive only one treatment combination?

Between-subjects design

In experimental research, categorical variables like a subject's gender or ethnicity are known as ___________.

Blocking variables

Which term refers to a treatment combination within an experiment?

Cell

The change in the dependent variable that occurs because members of one experimental group experienced different historical situations than members of other experimental groups is called a(n) ___________.

Cohort effect

An experimental construct refers to one of the possible levels of an experimental variable manipulation.

False

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

False

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

False

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

False

In an experiment, the researcher manipulates the dependent variable and measures its effect on the independent variable.

False

Participants in experimental research are typically referred to as respondents.

False

A(n) ___________________ effect is a nuisance effect occurring when the initial measurement or test alerts or primes subjects in a way that affects their response to the experimental treatments.

Testing

A set of high school students who take the ACT in their junior year perform better on the exam during their senior year because they know better how to take the exam due to what they experienced on the first exam. This is an example of a(n) _________________.

Testing effect

The people administering an experiment must be aware of the experimental hypotheses.

False

An experimental design element of procedure that unintentionally provides subjects with hints about the research hypothesis is called a(n) __________________.

Demand characteristic

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

False

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.

False

When a change in the wording of questions, a change in interviewers, or a change in other procedures causes a change in the dependent variable, a(n) ___________________ effect has occurred.

Specifically, 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 __________________.
