1In an ANOVA the F ratio is determined by dividing the [blank_start]between-groups variance[blank_end] by the [blank_start]within-groups variance[blank_end].
- Abetween-groups variance
- Bwithin-groups variance
2What does a larger F ratio show?
- AThere are larger systematic effects present
- Bthere are small systematic effects present
- Cthere are no systematic effects present
3One reason to use an ANOVA over multiple tests is...
- Ato reduce the likelihood of a type 1 error
- Bto reduce the likelihood of a type 2 error
- Cto be able to use more than one IV
4If a one way ANOVA produced MS (between) = 34 & MS within = 2, then the F ratio = [blank_start]17[blank_end]
- A17
5what is a factorial design?
- Awhen we have manipulated more than one IV
- Bwhen we have manipulated only one IV
6In a study examining depression scores and exam results on happiness, how many main and interaction effects would there be?
- A2 main, 1 interaction
- B2 main, 2 interaction
- C3 main, 3 interaction
7what figure should you examine in a multiple regression output to examine the influence that one predictor variable has had on the outcome?
- Aunstandardised beta
- Bstandardised beta
- Ccoefficients table
8when running analysis which of the following is a problem?
- Asystematic error
- Brandom error
9A type 1 error is when you say there is no effect when in fact there is.
- AVerdadeiro
- BFalso
10what is the standardised value used to ensure a type 1 error is not made?
- A5%
- B0.5%
- C10%
11Standard deviation is the square root of the variance.
- AVerdadeiro
- BFalso
12what is statistical significance dependent on?
- Apopulation size
- Bsample size
- Crandom error
13Unstandardised coefficients in regression analysis are measured in the same units as the original variable. Standardised are measured in standard deviation units of the original variable so they can be compared across different predictors.
- AVerdadeiro
- BFalso
14'the proportion of variance in the outcome accounted for by the predictor variable or variables" which of the following is this an explanation for?
- AR2
- Bfamilywise error
- Comnibus test
15how many outcome variables can a multiple regression examine in one model?
- Aone
- Btwo
- Cthree
16what method can you use to eliminate poor predictors in a multiple regression analysis?
- Abackwards elimination
- Bomnibus test
- Cpost hoc test
17A 95% confidence interval is the range in which we do not expect the population mean to fall within.
- AVerdadeiro
- BFalso
18[blank_start]Bonferroni correction[blank_end] is when you apply a certain criterion for significance based on the usual criterion for significance (0.05) divided by the number of tests performed.
- ABonferroni correction
19In an ANOVA the experimenter uses a fully factorial design, what is this?
- Awhen participants experience all conditions
- Bwhen participants experience one contition
20which statistical values from ANOVA output should you include when reporting?
- AF value
- Bdf
- CMSE
- Dp value
- ER2
21Which menu on spss would you access a mixed design ANOVA?
analyse - [blank_start]general linear[blank_end] model - [blank_start]repeated measures[blank_end]- Arepeated measures
- Bgeneral linear
22experimental and correlational are the two broad types of design when conducting quantitative research
- AVerdadeiro
- BFalso
23On a plot representing data what do two non parallel lines most likely represent?
- Aan interaction effect
- Ba main effect
- Cno effect
24[blank_start]magnitude[blank_end] ([blank_start]size[blank_end]) & [blank_start]direction[blank_end] ([blank_start]sign[blank_end]) are two pieces of information a coefficient r statistic gives you
- Amagnitude
- Bsize
- Cdirection
- Dsign
25Put the following correlation coefficients in order from weakest to strongest: [blank_start].02[blank_end], [blank_start]-.06[blank_end], [blank_start].4[blank_end], [blank_start]-.8[blank_end], [blank_start]1.0[blank_end]
- A.02
- B-.06
- C.4
- D-.8
- E1.0
26A negative relationship on a scatterplot would show points in a pattern that extend from lower left to upper left
- AVerdadeiro
- BFalso
27In an ANOVA, what do we use to compare all groups to determine which are significantly different to each other?
- Aomnibus test
