What common inferential error discussed in class best describes the following anecdote: In the medical world, a frequently observed phenomenon is that those who have adverse outcomes (death or permanent quality of life decrease) after being diagnosed with serious medical conditions exhibit serious vitamin D deficiencies (a statistically significant decrease when comparing those with adverse outcomes to those who recovered).  Since vitamin D is most associated with exposure to sunlight and low level UV radiation, many homeopathic practicioners recommend that getting more sunlight increases the probability that sick patients are more likely to recover.
