Answer 1

C

Question 2

A 3 × 2 within-subjects ANOVA will have?

A)One error term for the whole analysis
B)One error term for each main effect and one error term for each interaction
C)One error term for between participants and one error term for within participants
D)No errors of any significance

Answer 2

B

Question 3

In a within-participants analysis,it is possible to?

A)Calculate the main effect of studying for a test before eating breakfast
B)Predict whether your football team will win on Saturday
C)Calculate a degree of error for each effect
D)Split the error across all conditions

Answer 3

C

Question 4

Error is not a type of variance.

Question 5

Which of the following describes the mathematical ability of those not attending the after-school book club?

A)Not being in a sports team negatively affects mathematical ability.
B)There is no significant difference in mathematical ability between those on sports teams and those not.
C)Those on a school sports team are brilliant at maths tests.
D)Not being in book club precludes you from joining a sports team.

Question 6

Pupils attending the after-school book club scored better on the maths test.Of those attending book club,those who are not in a school sports team are better at maths.This is a correct interpretation of the data in Q10.

Question 7

The difference between conditions of one independent variable within one condition of the other independent variable is?

A)A degree of freedom
B)A simple effect
C)The main effect in a 2 × 2 ANOVA
D)An error

Question 8

A 2 × 2 between-participants ANOVA will have?

A)One error term for the whole analysis
B)One error term for each main effect and one error term for each interaction
C)One error term for between participants
D)No errors of any significance

Question 9

The overall effect of an independent variable on a dependent variable is called?

A)Indirect effect
B)Direct effect
C)Main effect
D)Interaction effect

Question 10

To differentiate between a factorial ANOVA and a simple ANOVA,there will be an interaction effect,two main effects and two independent variables present.

Question 11

Similar to Q6,in another study you are asked to look at educational attainment in three different cities by gender.The three conditions for educational attainment are 'left school at 16','completed A levels',and 'gained bachelor's degree or higher'.How would the ANOVA be represented?

A)2 × 3 × 2
B)3 × 2
C)3 × 3 × 2
D)1 × 2 × 3

Question 12

You are asked to go into a primary school and perform a study to look for any correlation between participation in school sports teams and whether the pupil attends the after-school book club.Each independent variable for the study has two conditions attached to it.How would the ANOVA be represented?

A)1 × 1 × 1 × 1
B)2 × 2
C)2 × 2 × 2 × 2
D)4 × 4

Question 13

A factorial ANOVA will be used to increase error variance.

Question 14

Which of the following are also calculated/presented in the same way for these two types of analysis?

A)Error
B)Degrees of freedom
C)Simple effects
D)None of the above

Question 15

Which of the following statements best defines a factorial ANOVA?

A)The analysis of variance to examine the effects of multiple independent variables on one dependent variable concurrently
B)The analysis of variance to examine the effect of one independent variable on multiple dependent variables concurrently
C)The analysis of variance to examine the effect of multiple dependents variables on one independent variable concurrently
D)The analysis of variance to examine the effects of one dependent variable on multiple independent variables concurrently

Question 16

An ANOVA of 4 × 3 × 2 represents what type of study?

A)4 independent variables,3 conditions,2 variances
B)3 independent variables,2 conditions,4 participants
C)2 independent variables,9 conditions,3 participants
D)3 independent variables,the first has 4 conditions,the second has 3 and the third has 2

Question 17

You are working with four independent variables on a between-participants study.How many sources of variance will there be?

A)3
B)4
C)12
D)16

Question 18

A factorial ANOVA is used to?

A)Investigate the interaction effect of the levels for both independent variables
B)Reduce the interaction effect for both independent variables
C)Increase the likelihood of achieving a statistically significant result
D)Reduce human errors

Question 19

What could be examined to determine whether there had been a violation of the homogeneity of variance?

A)Confidence interval
B)Mode
C)Mean
D)Standard deviation

Question 20

The partial η² is calculated/presented in the same way in both a within-participants ANOVA and a between-participants ANOVA.

Question 21

In a between-participants analysis,it is only possible to?

A)Calculate one degree of error
B)Calculate all degrees of freedom
C)Calculate multiple degrees of error
D)Ensure that the degree of error matches the standard deviation

Question 22

When is it appropriate to consider outliers?

A)Never
B)Before beginning ANOVAs
C)Always
D)Only when using simple random samples

Question 23

A factorial ANOVA allows us to examine the effects of a dependent variable on another dependent variable when not taking the independent variable(s)into account.
