Exam 2: Research Methods in Io Psychology

Marta develops a theory that suggests filling out a job application in crayon will lead to a lower probability of being hired. However, almost nobody fills out an application in crayon, so this finding will not affect anyone in a meaningful way. Marta's theory lacks:

A _____ provides information about the direction and magnitude of the relationship between two or more variables.

Correlations are relevant to I/O psychology because they are involved in making:

Explain the difference between an experiment and a quasi-experiment. Which approach has higher internal validity? Why?

Dr. Begley is conducting a study in a factory in which she is examining whether having employees wear uniforms affects their job satisfaction. In this study, her sample is very representative of other factory workers; however, because the employees work in an actual workplace, she cannot control other things that might affect their satisfaction. Her research is high in _____, but low in _____.

Beula has a new measure of charisma. She finds that her measure correlates .75 with another measure of charisma and correlates .45 with a measure of kindness. Based on this information, which statement is true?

The approach to science that involves starting with a theory and propositions and then collecting data to test those propositions is:

"Predictors," "precursors," and "antecedents" are all words we might use to describe:

Describe two ways in which technology has changed the way researchers conduct surveys.

What are the main differences in the inductive and deductive approaches to science?

Dr. Applesmith conducts a study in which he manipulates the light in a room while assessing participants' performance on a counting task. In this example, the light is the _____, and the performance on the counting task is the _____.

Which of these is a goal of science?

Independent variables are frequently referred to as:

Describe the components of the cyclical inductive-deductive model of research.

A researcher is conducting an experiment to test the effect of feedback on job performance. The researcher can exercise control over extraneous variables, such as intelligence, by:

A scientist who believes that behavior is orderly and systematic and does not happen by chance holds the basic assumption of science known as:

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

Which correlation indicates the strongest relationship?

Extraneous variables can severely damage which type of validity?

This criterion of a good theory states that it should be practical and help to describe, explain, and predict an important phenomenon. Thus, a good theory must be:
