Exam 9: Experimental Design Research Methods

To test the ability of a racial tolerance program for police officers, an experimental researcher 'rides along' with police officers to observe how they interact with racial and ethnic minorities. What type of threat to the external validity of this experiment's results is this problem?

An experiment applies a treatment to a single experimental group and measures the dependent variable both before and after the application of this treatment. What type of experimental design is being used?

An experiment includes equivalent experimental and control groups, a treatment or stimulus that is applied to the experimental group, and a post-test that measures the dependent variable after the experimental group has been exposed to the treatment. What type of experimental design is being used?

The two-group pre-test-post-test experimental design model includes an experimental group, treatment, a poshest, and:

An experiment has a single experimental group, a treatment or stimulus, and a post-test that measures the dependent variable after the treatment. What type of experimental design is being used?

An experimental design model would be helpful in a study involving faith-based counseling and recidivism among violent ex-offenders if:

A measure of the dependent variable prior to the application of the treatment in an experiment:

A measure of the dependent variable after the application of the treatment in an experiment:

An experiment has equivalent experimental and control groups; a treatment or stimulus that is applied to the experimental but not the control group; and protests and post-tests that measure the dependent variable prior to and after exposure to the treatment or stimulus. What type of experimental design is being used?

During an experiment a researcher decides to assign participants to the experimental and control groups based on their birthdays. The participants are juvenile offenders. Those born from January through June are assigned to the experimental group. The participants born from July through December are assigned to the control group. The experiment involves an assessment of academic achievement on the onset of juvenile delinquency. What type of threat to the external validity of this experiment's re

When research subjects change their behaviors after becoming aware of an experimental researcher's presence, it is referred to as:

An experiment has two experimental groups and two control groups; a treatment or stimulus that is applied only to the experimental groups; protests that measure the dependent variable prior to the treatment for one of the experimental groups and one of the control groups; and post-tests that measure the dependent variable after exposure to the treatment for all groups. What type of experimental design is being used?

External validity is related to which of the following research methods concepts?

The group that is exposed to the treatment or stimulus believed to cause a change in the dependent variable is known as the:

The one-group, no pre-test experimental design model does not include:

An experimental researcher working with chronic adult offenders uses a ten-item inventory as a pre-test. He uses the very same ten-item inventory as a post-test. The time frame between the pre-test and post-test was less than a week. What type of threat to the internal validity of this experiment's results is this problem?

During a multi-year experiment on the effect of an intervention program designed to reduce the potential for domestic violence, an experimental researcher learns that there is no difference in the frequency of domestic conflict between the men in the experimental and control groups. What type of threat to the internal validity of this experiment's results is this problem?

The one-group, no pre-test experimental design model includes:

An experimental design model might be helpful in a study involving bullying behavior if:

During an experiment to evaluate the effectiveness of a new public relations program used by a police department to improve its relationship with the community, an errant police officer shoots and kills an unarmed teenager. What type of threat to the internal validity of this experiment's results is this problem?
