Question 1

Cell

Answer 1

A single entry in a table, sometimes used to refer to one condition in an experiment, or to a combination of conditions in a factorial design.

Question 2

Factorial design

Answer 2

An experiment with more than one independent variable (also called a factor) with each factor having at least two levels ie two conditions

Question 3

Interaction

Answer 3

When the effect of one independent variable on the dependent variable depends on the level of another independent variable.

Question 4

IV-PV

Answer 4

A factorial design that includes both an experimental independent variable (IV) and a non-experimental participants variable (PV)

Question 5

Levels

Answer 5

The operationalization of the independent variable in an experiment, often referred to the conditioned groups

Question 6

Main effect

Answer 6

The direct effect of an independent variable on a dependent variable, ignoring any interaction with other variables.

Question 7

Marginal mean

Answer 7

In a factorial design, the average score of all participants in one condition of one independent variable, collapsing across all other variables.

Question 8

Mixed factorial design

Answer 8

A factorial experiment design that includes bot between subjects and within subjects variables.

Question 9

Mixed factorial design

Answer 9

A factorial experiment design that includes both between subjects and within subjects variables

Question 10

Moderator variable

Answer 10

A third variable that influences the relationship between an independent variable and a dependent variable. In a factorial design the effect of moderator variables are revealed as interactions

Question 11

Simple main effect

Answer 11

In a factorial design, the effect of one independent variable on the dependent variable, at one particular level of another independent variable.
