Exam 3: Methods for Research and Evaluation

If a test measures what it is supposed to measure, it is said to have:

Whereas ____ refers to whether a test measures what it is supposed to measure, ____ means that that the measure is consistent.

A test of aggressive behavior includes statements such as, "When I get mad I punch people in the face." These would represent:

Briefly describe case studies and explain why they are used. Include both the pros and the cons of this design.

Research based on things like observations of behaviors is classified as:

Briefly describe the constructs of reliability and validity. If you have to pick one, which would it be and why?

When a test is as short as possible but also comprehensive it is said to have:

Briefly define each of the following: Reliability Internal consistency Test-retest reliability Inter-rater reliability Split-half reliability Validity Face validity Content validity Construct validity Criterion validity Predictive validity Concurrent validity

Briefly design a study looking at different treatments for anxiety. Make sure you define and explain why you would or would not use each of the following: randomized controlled trial, control group, experimental group, placebo, single blind, and double blind techniques.

Hassan has developed a test for aggressive behavior. He finds that he only needs to calculate the even numbered questions for reliability instead of the entire test. This would indicate his test has good:

A test's ability to produce the same results over time is its:

A treatment is said to be _____ if the main variable influences the purported dependent variable; if p<.05 than the measure is said to be ______.

Briefly describe the advantages and disadvantages of a two-group design versus a three-group design.

If GRE scores are designed to predict intelligence and people who score 1,300 get all A's in graduate school, then the GRE would have high:

A(n) _____ seeks to determine if a particular service is needed and useful and, if so, for whom it would be best whether there is a need for it.

Terrell is performing a study on the effects of benzodiazepines on anxiety. Some patients are in the control group and others in the experimental group. Only Terrell knows who is in what group. This is known as a:

A variable that makes it difficult to determine the effect of the treatment variable on the dependent measure is known as an:

Logan takes the GRE and scores a combined 1,150. He retakes the test six months later and again scores a 1,150. This indicates that the test:

One of the advantages of a two-group design is that it:

Estefani and Stephania are looking at videos of bullying behaviors on playgrounds. They both look at a video of one child pushing another and code it as aggression. This illustrates:
