Flashcards in Chapter 12- Two Way ANOVA Deck (13):

1

## What is a Two Way ANOVA?

### A two way ANOVA is an analysis of variance. It has a factorial design of two or more independent variables. Each independent variable can have 2 or more levels. The dependent variable is scale

2

## What is the difference between a one way ANOVA and a two way ANOVA?

### There are 2 independent variables. The two independent variables have an effect in combination

3

## What is a factorial ANOVA?

### A factorial ANOVA is a general term for two way, three way and higher ANOVAS

4

## What is a factor?

### A factor is used to describe an independent variable in an ANOVA

5

## What is a mixed ANOVA?

### A mixed ANOVA is when one or more factors is between groups and one or more is within

6

## Why are 2 variables measured at one time?

### Researchers can assess the combined effects of two variables as well as their independent effects

7

## What is a main effect?

### A main effect is when the different level of one factor produce significantly different effects on the dependent variable, ignoring the other factor(s)

8

## What is an interaction?

### An interaction is an effect of one variable depends on the specific level of another variable

9

## What are the two types of interactions?

### Quantitative interaction and Qualitative interaction

10

## What is a quantitative interaction?

### A quantitative interaction is when one independent variable strengthens or weakens the effect of the other independent variable but the direction of the effect does not change

11

## What is a marginal mean?

### A marginal mean is the overall mean of a column or row

12

## What is a qualitative interaction?

### A qualitative interaction occurs when one independent variable reverses it effects or changes directions depending on the level of the other independent variable (cross over interaction
