Exam 13: More About Multi-Factor Experiments

A(n) ______ test is often used to analyze data in a factorial design.

Main effects are determined by ______ means for the rows and comparing means for the columns in a diagram of the factorial design data.

The primary advantages of a factorial design over simpler experiments are that a researcher can be more efficient in testing the effects of multiple independent variables in one experiment and can also examine the combined effects of those independent variables on the dependent variable.

In a factorial design, there is/are at least ______ independent variable(s).

Interactions between ______ variables can reveal interesting effects of the variables beyond what is seen in the main effects of each variable.

Factorial experiments can provide researchers with ______ information about behavior.

What are simple effects tests and when are they used?

One advantage of a factorial design is that a researcher can be more efficient in testing the effects of multiple ______ variables in one experiment.

Graphs are not useful in determining the type of interaction that occurred and should be followed up with additional statistical tests to determine exactly where the differences between the conditions in the interaction are in order to best describe the interaction effect.

The average mean scores for each level of an independent variable is the ______.

A test for an interaction effect compares means for ______.

If a ______ is created, an interaction can be seen in nonparallel lines.

In order to evaluate interaction effects, researchers should ______.

Graphs are useful in determining the type of interaction that occurred and should be followed up with additional statistical tests to determine exactly where the differences between the conditions in the interaction are in order to best describe ______.

Interactions between independent variables can reveal interesting effects of the variables beyond what is seen in the main effects of each variable.

Without including multiple ______ variables in a single experiment, we would not be able to detect the different effects a factor might have on behavior in different situations.

In the Bub et al. (2013) study it was hypothesized that knowing what action is appropriate for an object (e.g., holding a mug in your hand) can affect your identification of the object.

A graph is often best to examine whether the effects of a(n) ______ depend on the levels of other ______.

The Zimbardo (1973) experiment, where a randomly assigned role as a prisoner or guard in a mock prison affected participants' behavior, is an example of a ______ type of study.

The main effect is one type of effect tested in an analysis of variance (ANOVA).
