It can be used in a wide variety of situations. An example of a population may be United States citizens, women, or lawyers. The researcher can measure the amount of time multiple servers spend with multiple customers and how much the tip is from each customer. Descriptive research can be defined as studies conducted to find and describe characteristics of a specific population. An experimenters control over many aspects of the experiment often makes it hard to generalize the results to other situations.

The scatterplot will usually show the pattern of the correlation. The variables Results obtained through the experimental method are very useful, but they do not prove with 100% certainty that a singular cause will always create a specific effect. There is a very wide variety of this type of research. With experimental research groups, the people conducting the research have a very high level of control over their variables.
