Construct.

A test that is chosen to assess that is chosen to assess the abilities necessary to carry out the demands of a specific job can be referred to as a ? Professor Merenich hypothesis that a person's intellegence will determine how well the person will perform on the job. In this example, Intelligence is the ?

Predictor.

A research design that includes a manipulated independent variable, but does not have random assignment is called a(n)?

Quasi experiement

The variance of a distribution is the?

Squared Standard Deviation.

If the correlation between two variables is .90, this means that there is a?

Strong association between the two variables.

In order for an expert to present a theory as legal testimony, the theory must meet all of the following requirements EXCEPT:

it must be statistically significant at the 0.5 level.

To maximize the extent to which results of an experiment can be generalized to a larger population, the researcher should to all the following EXCEPT:

sample only one small group of people.

The standard deviation refers to ?

the typical amount of deviation from the mean.

An important distinction between an experimental design and a quasi experimental design is that ?

unlike a quasi experimental design, and experimental design randomly assigns participants to groups.

The most frequently occurring score within a distribution is the ?

Mode.

Dr. Duran, an I-O psychologist, found that as job satisfaction increases, employee absenteeism decreases. This is an example of a ___ relationship.

Negative.

Examining the correlation between new employee test scores and their job performance six months after they are hired proves a way to assess:

Predictive Validity.

Which sample would yield results with the most Generlizabiltiy?

A large Representative Sample.

A recent study found that as people's comment to their job increased, their absences from work decreased. Which correlation best represents this finding?

-.56.

The standard deviation of a distribution is 4. Therefore, the variance of the distribution is ?

16

What is the mean of the following data set? 1,2,2,7,2,4

3

if a researcher wants to examine whether a test is reliable over a reasonable time period, he or she might?

Administer the test to the same people at two different points in time and calculate a Correlation Coefficient between the scores taken at time one and the scores taken at time two.

According to the text, research designs in I-O psych, can be broken down into three basic types:

Experimental, Quasi-Experimental, Non Experimental

Jake want to establish a cause effect relationship between two variables. He should use ____ to establish causation between the two variables.

An experimental design.

T-test, Analyses of Variance, and Chi square tests are all examples of ?

The best way she can draw an inference about the relationship between music and performance would be to use?

Inferential Stats.

Dr. Groeneveld and Dr. Duran are investing whether drivers are wearing seatbelts. They stand on opposite street corners and tally how many drivers passing by are wearing their seatbelts. Which type of reliability does this approach assess when comparing their final tallies across a large number of drivers?

Inner-Rater Reliability.

The process used by I-O psychologists to develop an understanding of a job by identifying the duties of the job and the KSAO's required to perform the job is called a(an)?

Job analysis.

A score that always falls at the 50th percentile in a distribution is called the?

median.
