If you had data from a three-way Analysis of Variance to analyse, which of the following statements is
correct about the number of Partial eta-squared Effect Sizes you could report?
(a) Just one - the overall ES for the experiment
(b) Two - one for the overall experiment, and generalized eta-squared for metaanalysis purposes
(c) Six
(d) Three - answer>>(c) Six
In a report of an experiment you read that Glass ∆ = 0.65. To get this value the researcher divided the
group mean difference by ...?
(a) The variance adjusted for the correlation between the two groups
(b) The average of the standard deviations of the two groups
(c) The standard deviation of the control group
(d) The pooled standard deviation. - answer>>(c) The standard deviation of the control group
Which of the following is an example of a generalized linear model?
(a) multiple regression
(b) cluster analysis
(c) logistic regression
(d) All of the above. - answer>>(d) All of the above.
,You are surveying what people think about water pollution. To the best of your knowledge no one has
developed a previous scale of distress about water pollution, but you have included a number of
questions about it in your survey. To make up a measure of distress about water pollution you would
probably use:
(a) Exploratory factor analysis
(b) Confirmatory factor analysis
(c) Multidimensional scaling
(d) Cluster analysis - answer>>(a) Exploratory factor analysis
You have done an experiment in which children have been randomly assigned to either a normal or a
"New French" series of French classes. At the end of the term the children's knowledge of French is
tested. Because the children differ in general language ability (measured at the start of the
experiment) you are interested to control for this ability in assessing the experiment. To do this, in
analysing the experimental results you are most likely to use:
(a) Analysis of covariance (ANCOVA)
(b) Analysis of variance (ANOVA)
(c) Exploratory factor analysis
(d) Canonical correlation - answer>>(a) Analysis of covariance (ANCOVA)
Another name for the standardized covariance is?
(a) analysis of the covariance
(b) standard deviation
(c) correlation coefficient
(d) sampling distribution range - answer>>(c) correlation coefficient
,When dummy coding a multiple regression with two categorical variables (criminal status and country
of origin), if there are 6 country of origin categories, how many dummy variables are necessary to
code country of origin?
(a) it depends on the number of categories for criminal status
(b) 5
(c) 6
(d) 7
(e) 8 - answer>>(b) 5
When dummy coding a multiple regression for an interaction with two categorical variables (religion
and ethnicity), if there are 5 religion categories, how many dummy variables are necessary to code the
interaction of religion and ethnicity?
(a) it depends on the number of categories for ethnicity
(b) 5
(c) 6
(d) 4
(e) 10 - answer>>(a) it depends on the number of categories for ethnicity
If a person wants to predict whether a person drinks alcohol or not (binary) using the big 5 personality
scales (Openness, Conscientiousness, Extroversion, Agreeableness and Neuroticism), the most
appropriate analysis would be
(a) survival analysis.
(b) discriminate analysis.
(c) logistic regression.
(d) multivariate analysis of variance (MANOVA).
, (e) multiple regression - answer>>(c) logistic regression.
If a person wants to test differences between a drug experimental group and placebo control group
for a number of dependent continuous variables, the most appropriate analysis would be
(a) survival analysis.
(b) discriminate analysis.
(c) logistic regression.
(d) multivariate analysis of variance (MANOVA).
(e) multiple regression. - answer>>(d) multivariate analysis of variance (MANOVA).
The square root of the covariance of a variable with itself is the
(a) covariance.
(b) variance.
(c) correlation.
(d) standard deviation. - answer>>(d) standard deviation.
If the presence of noise alters the influence of amphetamine use on video game performance, then
noise is a ______________variable.
(a) correlated
(b) mediator
(c) moderator
(d) main-effect - answer>>b) mediator
