Research Projects
This is targeted at undergraduate research projects of the type I facilitate in my Research Methods and Advanced Research Methods courses. These suggestions and tools are likely to be insufficient for other kinds of projects.
What to study?
Hypotheses and research questions
Literature reviews
Research designs by variable measurement scale
Numerical outcome (Y)
- Multiple categorical predictors: Factorial ANOVA
- Multiple numerical predictors: Multiple regression
- Numerical and categorical predictors: ANCOVA (analysis of covariance)
Binary outcome (Y)
If you're in my class, please try to avoid this. It can be done in ways (conceptually and functionally) similar to designs with a numerical outcome variable, but you will need to learn how to set things up a bit differently, and you will need to learn how to interpret some new kinds of statistics.
Categorical outcome (Y)
If you're in my class, don't do this.
Manipulating variables
Surveys
Survey basics
Qualtrics-specific tips
SONA basics
Qualtrics-SONA integration
Multi-item scales
Ethics
Data preparation
You will probably need a spreadsheet program/application like Calc, Excel, Numbers, or Google sheets, to do data wrangling.
Data analysis
Note: Most of this assumes you are using JASP. If you're using another stats program like Minitab, Stata, SPSS, or SAS, you will probably have to adapt these instructions. If you're using R, you probably don't need these instructions.
