Exam 2: Research Methods in I0 Psychology

To study the effectiveness of employee training you train 20 volunteers and compare their post-training performance to that of 20 non-volunteers.What type of research design have you used?

You want to know whether group size influences the success of employee training.Rather than do a new study you find 20 previous studies on this question and statistically combine their results.What is this analysis called?

To draw causal conclusions about a research question,one should use:

An attribute or characteristic of people or things that can take on different values is called:

You want to know whether the trained and untrained employees at your organization differ in their job performance.The variability in performance observed among the trained employees is called

You want to study the effects of training on performance.Because you must get permission to train people,you ask for volunteers.You train half the volunteers,and then measure the performance of both trained and untrained volunteers.You have used

When I/O psychologists perform job analyses they often take notes on the employees' actions by observing employees without the subjects being aware of the researchers.This is an example of a(n)

The same physical location can be the setting for either a field or a laboratory study.The phenomenon being studied is what differentiates the two.

With categorical measurement the numbers represent the amount of the characteristic in question.

Approximately what percentage of I/O studies published in major journals was performed in laboratory settings?

What is the mean of the following set of numbers: 1,2,6,8,5,3,4,3?

At Qzork each applicant is interviewed by two different managers who then rate each job candidate on a series of competencies.If you compare how well these two managers agree on their ratings of each applicant you are measuring

You want to know if part-time employees become more or less happy with their employment over time.Thus,you give a questionnaire to 100 new hires and four months later give the same questionnaire to the same employees.What type of research design have you used?

When the outcome of an inferential statistical test is said to have statistical significance we would conclude that the observed results are most likely due to

In which of the following research designs would it be MOST difficult to draw causal conclusions?

Procedures that allow researchers to rule out certain explanations for results other than the hypotheses they wish to test are referred to as __________ procedures.

When I/O psychologists conduct research in organizational settings they are said to be conducting _________ research.

In experimental studies the __________ variable is assumed to be the cause of the change in the _________variable.

You have been hired by an organization to conduct an analysis of the productivity of the production department and the number of coffee breaks the employees take.You collect your data by observing the employees while pretending to be a new hire in the department.This type of observation is called a(n)
