Questions in this quiz (18)
1If there are more levels, there are more comparisons, which increases likelihood of:
- AType 1/alpha error (finding significant results when there isn't one)
- BType 2/beta error (failing to reject the null)
- CType 1/alpha error (failing to reject the null)
- DType 2/beta error (finding significant results when there isn't one)
2If there are more levels, there are more comparisons, which increases likelihood of type 1/alpha error. This is known as:
- AFamilywise error
- BOrder effects
- CCohen's d
- DPearson's r
3How can you reduce Familywise error:
- AStricter probability
- BIgnoring it
- CHaving more levels
- DUsing a t-test
4An ANOVA is an omnibus test, meaning:
- AIt discovers overall difference, not where it lies, reducing Familywise error by conducting 1 test rather than many t-tests
- BDiscovers where the difference lies by using Tukey
- CCompares only 2 groups
- DIt has nothing to do with main or interaction effects
5Two-way ANOVA means there are:
- ATwo IV's
- BOnly 2 groups
- COne IV
- DThree IV's
6An example Two-way ANOVA is: impact of gender AND type of exercise ON depression
- ATrue
- BFalse
7In this last example two-way ANOVA, identify which are predictor variables and which are outcome variables: (3)
- AGender: predictor
- BExercise: predictor
- CDepression: outcome
- DDepression: predictor
8If 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:
- A3 x 2 design
- B2 x 2 design
- CT-test
- DOne-way ANOVA
9If both IV's/predictors are between groups = [blank_start]fully between[blank_end] design
- Afully between
- Bmixed
- Cfully within
- Dsilly
10If 1 predictor is within, and the other is between, it is known as a mixed design
- ATrue
- BFalse
11If 1 predictor is within, and the other is between, it is known as a fully between design
- ATrue
- BFalse
12Identify one-way and two-way ANOVA: (2)
- AOne-way = 1 effect with more than 2 levels (IV or DV)
- BTwo-way = 3 effects (2 main and 1 interaction)
- COne-way = 3 effects (2 main and 1 interaction)
- DThree-way = 1 effect with more than 2 levels (IV or DV)
13A three-way ANOVA has 7 effects (3 main, 4 interaction)
- ATrue
- BFalse
14On SPSS, you'd conduct a two-way ANOVA by:
- AAnalyse - General linear model - Univariate
- BAnalyse - Compare means - one-way ANOVA
- CAnalyse - Compare means - Independent t-test
- DAnalyse - Plots
15The lower the SD, the..
- AMore accurate model
- BMore inaccurate model
16'3 x 2 x 3' indicates what? (2)
- ANumber of factors by looking at how many numbers (in this example, 3)
- BNumber of levels within each factors by looking at the value of each number (e.g. factor 1 has 3 levels)
- CEffect size using Cohen's d
- DThe result of a Tukey post-hoc
17What is a factorial design?
- AWhen we have manipulated more than 1 IV/factor
- BWhen we have manipulated only 1 IV/factor
- CWhen there is more than 1 DV/outcome
- DSystematic error
18How many effects in this design?
- A2 main, 1 interaction
- B3 main, 4 interaction
- C3 main, 1 interaction
- D2 main, 4 interaction
