Practice question · Multiple choice
Extraversion and introversion are not two personality types. What are they?
Hints
- Ask what a score in the middle of the scale would mean under each reading.
- All five of the Big Five are the same kind of thing.
Show the answer
B. Two ends of one continuous dimension, most people mid-way
Why
A dimension carries the information a dichotomy throws away. Splitting a continuous trait at the mean is a measured loss of statistical power as well as a conceptual error.
