Out of research questions and statistical techniques, which is the job and which is the tool?
RQ = job
Stat technique = tool
The what guides the choice of what?
The research question guides the choice of the statistical technique.
3 analytical techniques that assess the degree of relationship between variables
- Bivariate correlation
- Bivariate regression
- Multiple regression
Analytical technique for “Are caffeine intake and reaction time related?”
Bivariate correlation
Analytical technique for “Does caffeine predict reaction time?”
Bivariate regression
Analytical technique for “Do caffeine intake and age predict reaction time?”
Multiple regression
5 types of analytical techniques that look at the significance of group differences
- Repeated measures t-test
- Independent samples t-test
- One-way within subjects ANOVA
- One-way between subjects ANOVA
- Factorial ANOVA
Analytical technique for “Is reaction time faster in coffee group compared to placebo?”
Independent samples t-test
Analytical technique for “Is reaction time faster in the same group of participants when they drink coffee compared to a placebo”
Repeated measures t-test
Analytical technique for “Is there a change in reaction time following caffeine consumption?”
Both t-tests are suitable, and it is only when research design is refined based on other considerations (constraints, maximising power etc.) that you are led to specific technique.
Analytical technique for “Do reaction time scores differ across groups with different levels of caffeine consumption (e.g., 0mg, 50mg vs. 100mg)”
One-way between groups ANOVA
Analytical technique for “Do reaction time scores differ when we give the same group of participants different levels of caffeine (0mg, 50mg, and 100mg)?”
One-way within groups ANOVA
Analytical technique for “Does the influence of caffeine consumption on reaction time differ depending on reinforcement type?”
Factorial ANOVA
2 most important tools in our toolkit to use if we aren’t familiar with a statistical technique?
- Conceptual understanding of different types of data and variables.
- research skills (ability to locate useful resources)
What could you do if you needed to identify an appropriate statistical technique (based on certain characteristics of the dataset)?
Look at statistical decision trees
Analytical technique for “Do caffeine intake and age predict whether someone is an honours student or not”?
Logistic regression
(DV is categorical)
