Bias (+ Confounding?)
Fragment of a discussion from Course talk:STAT 550
1. Experimentar Bias：occurs when the measurements obtained in a study are influenced by the experimenter's expectations regarding the outcome of the study. 2. Recency Bias: cause people to more prominently recall and emphasize recent events and observations than those that occurred in the near or distant past. 3. Confounding bias: occur when two factors are associated and the effect of one is confused with or distorted by the effect of the other.
