Q1
In your own words (do not use any quotes), answer the following:
What does variance represent when considering ANOVAs?
What underlies the logic behind how variance is partitioned in a one-way between groups ANOVA?
Why are repeated measures ANOVAs more powerful than between groups designs? Answer in terms of variance in the data.
Q2
Provide a brief yet thorough description of what research design and quantitative analyses you would use for the following scenarios.
A researcher is investigating the effectiveness of a new therapy developed to treat Nomophobia, a fear of being without a mobile phone. The researcher has a scale that measures the level of Nomophobia (higher scores = higher levels of Nomophobia) and 150 volunteer sufferers of Nomophobia. The therapy can be performed on groups and consists of a single two-hour session.
A researcher and her colleagues have assembled 100 questions that they believe cover all the facets of the construct buffoonery. They want to use these questions to develop a new Buffoonery Scale.
Q3
In your own words (do not use any quotes), answer the following:
Why can outliers be problematic?
Why should we bother checking the assumptions for parametric tests (e.g., ANOVAs, multiple regression, etc.)?
Why should we report effect sizes and/or confidence intervals with our p values?
Q4
In your own words (do not use any quotes), explain the difference between statistical significance and practical significance and explain how each of these can be evaluated/reported.
Provide an example of how you might have statistical significance but not practical significance within the same study.
Q5
A researcher was interested to see how Egoistic (values power and wealth), Altruistic (values equality and human welfare), and Biospheric (values all living things) value orientations predicted pro-environmental behaviour. Higher scores on these measures equals higher value orientations and more pro-environmental behaviour.
