Dr. Reynоlds recently stаrted using а nоvel drug tо treаt patients with chronic migraines. She noticed that patients with exceptionally severe migraines, averaging around 20 headache days a month, reported a drop to about 14 headache days a month after starting the drug. However, patients with around eight headache days a month saw no change after beginning the medication. Dr. Reynolds is enthusiastic about the results for the severely affected group, believing the drug made a significant difference for them. Which type of “dirty data” best explains why the patients with the most severe migraines (≈ 20 headache days → ≈ 14) appeared to benefit, while those with milder migraines showed no change after starting the drug? [1] Why is the pattern in Dr. Reynolds’ results an example of the dirty-data phenomenon you chose in Question 1? [2] How might this statistical phenomenon influence Dr. Reynolds’ perception of the drug’s effectiveness? [3] Suppose Dr. Reynolds repeats the study and includes a control group that receives an identical-looking pill with no active ingredient. If both groups improve equally, which source of dirty data was most likely responsible for the original apparent benefit? [4]
