Exam 2: Research Methods in Io Psychology

When an experiment uses college students as participants, some people may raise concerns that the results are not generalizable to employees in the "real world." This represents a concern about:

Describe two ways in which I/O psychologists can control for extraneous variables in research.

The MOST frequent single score in a distribution is called the:

Meena, using an archival data set for her research, notices that the data were collected from the same group of children when they were in first, second, and third grade. This data set is:

In the data set 3 5 5 6 7 8 8 9 10 10 10 15 17 20 20, what is the range?

How are experimental methods of research different from other research methods?

The goal of science that involves the accurate portrayal of a certain phenomenon is known as:

Robbi has a new measure of dutifulness. She finds that her measure correlates .62 with another measure of dutifulness and correlates .35 with a measure of orderliness. Based on this information, which statement is true?

Which of these would NOT be a type of data collection one would use for an observational method of research?

Professor Fisk has developed a theory that contains statements that are verifiable by experimentation. The professor's theory has met the criterion for a "good" theory that is known as:

Which of these is the LEAST common method of collecting data in I/O psychology research?

Jerome wants to determine whether a test can identify employees who will be top performers. He administers his test to his employees, and he finds that its results correlate with their current performance. He has demonstrated:

Darnell works in HR. He notices in his HR data that managers who speak more than one language have more satisfied employees. He proposes the theory that language skills relate to better communication skills with subordinates. Darnell is using:

The type of variable that can contaminate the results of an experiment and may be an alternative to a causal relationship is known as a(n):

When squaring a correlation coefficient (r²), the resulting value tells how much variance in the criterion is explained by the predictor. This statistic is also known as the coefficient of:

A case study is an example of a(n):

Dr. Wickersham wants to examine how light affects participants' performance on a counting task. So she has two groups, one that works under dim light, and one that works under bright lights. She finds that those in the dim-light condition perform better. However, one of her research assistants admits that he gave those in the dim-light condition extra time to complete the task. Now Dr. Wickersham is not sure whether those in the dim-light condition did better because of the lighting or because of the extra time they received. The extra time on the test is an example of a(n):

What are three of the five criteria of a good theory?

Chatna is a math teacher. She teaches two sections of math and wants to make sure her students don't cheat on the test. She creates two different versions of a math test, and ensures that they measure the same thing and are equally difficult. Chatna has established:

The extent to which results in an experiment generalize to other people, settings, and times is referred to as:
