Which of the following is not a problem post hoc comparisons need to correct for?

A) Familywise error rates
B) Per comparison error rates
C) Sibling error rates
D) Experimentwise error rates

Answer 3

Sibling error rates

Question 4

A) There is an interaction and no main effects.
B) There is an interaction and one main effect.
C) There is no interaction and one main effect
D) There is no interaction and two main effects.

Question 5

What would the substantive interpretation of this analysis (Q8) be?

A) Context has an effect on recall
B) Cue-type has an effect on recall
C) Context and cue-type have an effect on recall.
D) Context and cue-type have an effect on recall, but the effect of context depends on cue-type.

Question 6

In the same context as Q4, consider the graph below. What does it suggest might be inferred?

A) There is an interaction and no main effects.
B) There is one main effect and no interaction.
C) There are two main effects and no interaction.
D) There is an interaction and two main effects.

Question 7

Research was conducted in which employees were given client facts to learn in either quiet offices or noisy call-centre type offices. On later recall either congruous or non-congruous cues for recall were given and recall was either in the same or different context of learning. What design is this experiment?

A) Two-factorial fully independent measures
B) Two-factorial fully repeated measures
C) Two-factorial one independent and one repeated measures factors
D) Three-factorial

Question 8

Consider the table below, which displays data from the experiment of Q8. What value should appear where XXX appears?
Dependent Variable: number correct

A) 28.276
B) 1017.925
C) 1
D) Not enough information

Question 9

How many dependent variables does a two-way ANOVA have?

A) One
B) Two
C) Three
D) Four

Question 10

What value should appear where YYY appears?

A) 316.406
B) 11.19
C) 1
D) Not enough information

Question 11

Which of the following questions should not be answered by employing a two-way ANOVA?

A) Does one of the factors systematically affect the results?
B) Are mean responses consistent across all levels of the factor?
C) Do two factors interact with each other?
D) Does one level of the factor affect the dependent variable significantly more than others?

Question 12

If a study has employed a two-way mixed ANOVA, what does this mean?

A) There were men and women participants in the study.
B) There were two factors in the study each with different numbers of levels.
C) There was a repeated-measures factor and an independent-measures factor in the study.
D) The researchers couldn't make up their minds about how to do the study.

Question 13

An experiment was conducted to look at the positive work-motivation effects of imagery on different people. A group of male staff was compared against a group of female staff. Both groups received presentations of positive images (e.g. cats and bunnies), neutral images (e.g. duvets and light bulbs), and negative images (e.g. corpses and vivisection photographs). Positive work motivation was measured by individual work productivity (high values indicate positive work motivation) both before and after each batch of images. The order in which participants saw the batches of positive, neutral and negative images was randomized to avoid order effects. It was hypothesized that positive images would increase positive work motivation, negative images would reduce motivation and neutral images would have no effect. Differences between the subject groups (male and female staff) were not expected. What technique should be used to analyse these data?

A) Two-way mixed ANOVA
B) Three-way repeated-measures ANOVA
C) Two-way mixed ANCOVA
D) Three-way mixed ANOVA

Question 14

Breaking down the total variance is referred to as?

A) Parting
B) Partitioning
C) Partition walls
D) Piecing

Question 15

In a factorial design with two factors - customer satisfaction and age - it appears that values for the former depend on the age of the customer. What is this type of effect called?

A) A main effect
B) An interaction effect
C) A factorial effect
D) An error
