The scientific method The scientific method is a way scientist and psychologist study and test a hypothesis. A hypothesis is a guess of the outcome of your research. However there is still a scientific process to coming up with a hypothesis. After you have come up with a question determine the characteristics of the comparison distribution. Determine the cutoff sample score on the comparison distribution at which the null hypothesis should be rejected. Determine your sample’s score on the comparison distribution. Decide whether to reject the null hypothesis then. Then after that psychologist use the scientific method to prove a theory or hypothesis (Arthur Aron, Elaine N. Aron, Elliot J. Coups, 2009). Scientific method is used to collect data and answer questions. This method consist of formulation of the problem, design of the study, collection of data, analysis of data, and the final conclusion of the data.

Aron, Elliot J. Coups, 2009).
In conclusion scientist and psychologist have been using this method to study people and science for years. Using the scientific method correctly not only helps to answer your question precisely and accurately but also add creditability to your research and makes it easier for other to use your work as secondary data.
