- The experiment should use studies or analytics to obtain some sort of private information from the subjects. (<u>such as test scores and subjects' anxiety level)</u>
- The experiment should make some sort of intervention that can be used to measure its hypothesis. (<u>the test above could divide the subjects into two groups. First group of female subjects could be make to take the test without the presence of male subjects while the second group do the test with the presence of male subjects)</u>
- The researchers need to interact with the subject in a certain way.
<u>(meaning that the subjects can't be anonymous to the researchers</u>)

Although New York was the first state in the USA to have laws against DUI as early as 1910 it was still a common practice for the people who did get arrested to get away with a fine or a slap on the wrist with the vehicle.
The laws would not get more strict until the vehicles themselves became more commonplace in the country and until 1930s it was possible to get away with drunk driving in certain southern states even when the person was arrested.
