"In 2007 a study of 231,000 New Jersey heart attack patients showed that those admitted on a weekday had a 12% chance of death within 3 years compared with 12.9% admitted on a weekend."
What are the possible statistical pitfalls of this? (may have more than one response)
- sample too small
- samples were not random
- conclusion from a rare event
- poor survey methods
- assuming a casual link that was not true
- unconscious bias
- generalization to individuals
- significance vs. importance
