Pregunta 1
Pregunta
If there are more levels, there are more comparisons, which increases likelihood of:
Respuesta
-
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)
Pregunta 2
Pregunta
If there are more levels, there are more comparisons, which increases likelihood of type 1/alpha error. This is known as:
Respuesta
-
Familywise error
-
Order effects
-
Cohen's d
-
Pearson's r
Pregunta 3
Pregunta
How can you reduce Familywise error:
Respuesta
-
Stricter probability
-
Ignoring it
-
Having more levels
-
Using a t-test
Pregunta 4
Pregunta
An ANOVA is an omnibus test, meaning:
Respuesta
-
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
Pregunta 5
Pregunta
Two-way ANOVA means there are:
Respuesta
-
Two IV's
-
Only 2 groups
-
One IV
-
Three IV's
Pregunta 6
Pregunta
An example Two-way ANOVA is: impact of gender AND type of exercise ON depression
Respuesta
- True
- False
Pregunta 7
Pregunta
In this last example two-way ANOVA, identify which are predictor variables and which are outcome variables: (3)
Respuesta
-
Gender: predictor
-
Exercise: predictor
-
Depression: outcome
-
Depression: predictor
Pregunta 8
Pregunta
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:
Respuesta
-
3 x 2 design
-
2 x 2 design
-
T-test
-
One-way ANOVA
Pregunta 9
Pregunta
If both IV's/predictors are between groups = [blank_start]fully between[blank_end] design
Respuesta
-
fully between
-
mixed
-
fully within
-
silly
Pregunta 10
Pregunta
If 1 predictor is within, and the other is between, it is known as a mixed design
Respuesta
- True
- False
Pregunta 11
Pregunta
If 1 predictor is within, and the other is between, it is known as a fully between design
Respuesta
- True
- False
Pregunta 12
Pregunta
Identify one-way and two-way ANOVA: (2)
Respuesta
-
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)
Pregunta 13
Pregunta
A three-way ANOVA has 7 effects (3 main, 4 interaction)
Respuesta
- True
- False
Pregunta 14
Pregunta
On SPSS, you'd conduct a two-way ANOVA by:
Respuesta
-
Analyse - General linear model - Univariate
-
Analyse - Compare means - one-way ANOVA
-
Analyse - Compare means - Independent t-test
-
Analyse - Plots
Pregunta 15
Pregunta
The lower the SD, the..
Respuesta
-
More accurate model
-
More inaccurate model
Pregunta 16
Pregunta
'3 x 2 x 3' indicates what? (2)
Respuesta
-
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
Pregunta 17
Pregunta
What is a factorial design?
Respuesta
-
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
Pregunta 18
Respuesta
-
2 main, 1 interaction
-
3 main, 4 interaction
-
3 main, 1 interaction
-
2 main, 4 interaction
