Frage 1
Frage
If there are more levels, there are more comparisons, which increases likelihood of:
Antworten
-
Type 1/alpha error (finding significant results when there isn't one)
-
Type 2/beta error (failing to reject the null)
-
Type 1/alpha error (failing to reject the null)
-
Type 2/beta error (finding significant results when there isn't one)
Frage 2
Frage
If there are more levels, there are more comparisons, which increases likelihood of type 1/alpha error. This is known as:
Antworten
-
Familywise error
-
Order effects
-
Cohen's d
-
Pearson's r
Frage 3
Frage
How can you reduce Familywise error:
Antworten
-
Stricter probability
-
Ignoring it
-
Having more levels
-
Using a t-test
Frage 4
Frage
An ANOVA is an omnibus test, meaning:
Antworten
-
It discovers overall difference, not where it lies, reducing Familywise error by conducting 1 test rather than many t-tests
-
Discovers where the difference lies by using Tukey
-
Compares only 2 groups
-
It has nothing to do with main or interaction effects
Frage 5
Frage
Two-way ANOVA means there are:
Antworten
-
Two IV's
-
Only 2 groups
-
One IV
-
Three IV's
Frage 6
Frage
An example Two-way ANOVA is: impact of gender AND type of exercise ON depression
Antworten
- True
- False
Frage 7
Frage
In this last example two-way ANOVA, identify which are predictor variables and which are outcome variables: (3)
Antworten
-
Gender: predictor
-
Exercise: predictor
-
Depression: outcome
-
Depression: predictor
Frage 8
Frage
If gender (predictor 1) has 2 levels (male or female) AND exercise (predictor 2) has 3 levels (cardio, strength, control), this can be described as a:
Antworten
-
3 x 2 design
-
2 x 2 design
-
T-test
-
One-way ANOVA
Frage 9
Frage
If both IV's/predictors are between groups = [blank_start]fully between[blank_end] design
Antworten
-
fully between
-
mixed
-
fully within
-
silly
Frage 10
Frage
If 1 predictor is within, and the other is between, it is known as a mixed design
Antworten
- True
- False
Frage 11
Frage
If 1 predictor is within, and the other is between, it is known as a fully between design
Antworten
- True
- False
Frage 12
Frage
Identify one-way and two-way ANOVA: (2)
Antworten
-
One-way = 1 effect with more than 2 levels (IV or DV)
-
Two-way = 3 effects (2 main and 1 interaction)
-
One-way = 3 effects (2 main and 1 interaction)
-
Three-way = 1 effect with more than 2 levels (IV or DV)
Frage 13
Frage
A three-way ANOVA has 7 effects (3 main, 4 interaction)
Antworten
- True
- False
Frage 14
Frage
On SPSS, you'd conduct a two-way ANOVA by:
Antworten
-
Analyse - General linear model - Univariate
-
Analyse - Compare means - one-way ANOVA
-
Analyse - Compare means - Independent t-test
-
Analyse - Plots
Frage 15

The lower the SD, the..
Antworten
-
More accurate model
-
More inaccurate model
Frage 16
Frage
'3 x 2 x 3' indicates what? (2)
Antworten
-
Number of factors by looking at how many numbers (in this example, 3)
-
Number of levels within each factors by looking at the value of each number (e.g. factor 1 has 3 levels)
-
Effect size using Cohen's d
-
The result of a Tukey post-hoc
Frage 17
Frage
What is a factorial design?
Antworten
-
When we have manipulated more than 1 IV/factor
-
When we have manipulated only 1 IV/factor
-
When there is more than 1 DV/outcome
-
Systematic error
