Ms. Naomi Winkler feels rather uncomfortable that her managerial decisions, especially on personnel matters, are often based on intuition and hunches. She realizes that scientific research would help her make good, sound decisions, but she does not know how exactly it is done. Help Winkler by:

1. Explaining in detail the method by which scientific research is done, and
2. Discussing how one knows whether the research done is in fact, scientific.
