Why do you require a control group for observational data?
- yummyfajitas 16y agoTo answer the question of how many bankruptcies are caused by medical bills, you must compare a group of people with medical bills in excess of $1001 (or perhaps a gambling problem) to a similar group of people without medical bills/gambling problems/birth/adoption. If, (for instance), 50% of the first group and 49% of the second group goes bankrupt, then only 2% of bankruptcies are caused by medical bills. Without the control group, you have literally no idea.
