Define the key terms

  1. Biased measurements: measurements that are changed by the situation
  2. Suppression: measurements that avoid extreme values
  3. Skew: where one tail of a distribution is longer than the other

Fill in the gaps

  2. The presence of skew usually doesn’t affect Type I errors.
  3. Random variability in a measurement reduces the measured effect size.
