Define the key terms
- Biased measurements: measurements that are changed by the situation
- Suppression: measurements that avoid extreme values
- Skew: where one tail of a distribution is longer than the other
Fill in the gaps
- With Categorical variables, more categories increases Type II errors.
- The presence of skew usually doesn’t affect Type I errors.
- Random variability in a measurement reduces the measured effect size.
