Answer:
Non-participant observation
Explanation:
Patti does an observation type study. These types of studies can be divided into two groups: participant and non-participant observation.
As Patti wants to be unnoticed by the children, she is using the non-participant approach to studying. Here, the researcher does not form a part of a group and/or even becomes a member of it but deliberately stays apart from it. His main goal is to observe the behavior of such a group in a natural setting and without interfering himself.
Answer: a. When prices in the stock market are up nothing happens. If they are down, the economy is in trouble.
Explanation:
The beauty of the economy is when the stock market is up. It means there would be more money in circulation to do businesses and when businesses are done the economy is wealthy and everyone is affected positively to a great extent. When there is a crash in the stock market it demoralizes the economic growth and lower stock price would mean a reduction in money used in businesses as companies won't want to commit much funds to doing business.
