Since I've had seven different team projects during the 2014 calendar year with 17 different partners (not including the two people who dropped out of the groups, and counting my two repeat partners only once), I decided to go back in time and compare the team evaluations I've written. I had some fun with Microsoft Excel's correlation coefficient formula, and here are my not-too-scientific findings:
- Being married was the strongest predictor of success in a team project.
- Introverts were somewhat more effective than extroverts (although there were several students who were near the center of the personality spectrum, who didn't have as much of an impact).
- Female students were somewhat more effective than males.
- Older students tended to be more effective than younger ones.
- People with dark hair were more effective than those with blond hair. Go figure.
- Students from my own program of study were generally better than those on other degree paths.
- The difference in effectiveness between white students and black students was negligible.
Don't expect this less-than-scholarly research to appear in your favorite academic journal.
