Research Statistics and Psychology

Psychology is “the scientific discipline that studies psychological and biological processes and behavior in humans and other animals” (Psychology, 2013).  Psychologist study the human and behavior to figure out why people think, feel and do the things that they do.  Psychologist observe individuals, ask questions, develop theories and conduct experiments to get a better understanding of human nature and how they can help improve the lives of individuals. The two main components of psychology are research and statistics.  I plan to briefly define research and the scientific method and discuss how it applies to psychology, compare and contrast the characteristics of primary and secondary data and explain the role of statistics in research.
The Merriam-Webster defines research as a “studious inquiry or examination; especially: investigation or experimentation aimed at the discovery and interpretation of facts, revision of accepted theories or laws in the light of new facts, or practical application of such new or revised theories or laws” (Merriam-Webster, 2013) .  The scientific method in research has five steps which begin by asking a question which seems really simple but in order to have accuracy the question needs to be about something that can be measured which is knows as quantitative data when developing statistics. Once you have determined your scientific problem you have to develop a hypothesis, which is “merely a good quality speculation, a guess about how or why something happens” (Cowen, 2006).  The next step is to test your hypothesis by performing experiments and making observations.  After conducting your experiments, record your observations to detail what your findings were.  The final step in the scientific method is to draw a conclusion by comparing the results of the experiment to the hypothesis to determine whether the hypothesis was true or false. 
In conducting research there are two types of data, primary and secondary.  Data is very important to the research process because it is the information a researcher collects from their experiments to support their hypothesis.  Primary data is information that is collected by the researcher while doing an experiment through observation and interviews.  Secondary data is “information that is gathered from existing data for purposes other than those for which they were originally collected” (Psychology, 2000).  Secondary data can be used to support the primary data that was collected during the experiment.
Data is very important in the research process because it helps provide statistics from the experiment.   Statistics for psychology defines “statistics is a method of pursuing truth.  As a minimum, statistics can tell you the likelihood that your hunch is true in this time and place and with these sorts of people.  This pursuit of truth, or at least its future likelihood, is the essence of psychology of science, and of human evolution” (Aron, Aron,  & Coups, 2009)Statistics are important for psychology because they help determine whether the accuracy of information given from research is correct.  Statistics also provide evidence that back up the subject and conclusion of the research.
Every psychological study has a goal that needs to be met and in order for that to happen researchers must be able to describe, explain, predict and perhaps have an effect on mental processed of behavior and this is how statistics are developed.  For example, I personally believe that online social networking have negative effects on personal relationships.  if I wanted to know how many people agree with what I said and feel that online social networking effects how people interact with each other in real life, I would first have to explain a little more in depth why I believe that to be so, then I would create a questionnaire randomly asking fifty people in different age groups, race and gender how often they participate in online social media versus how much time they actually spend with their friends and how it has affected their personal relationships with friends and family.  The information that I gather from the questionnaire would be my primary data which would calculate statistics based on my hypothesis.  I could than compare my primary data with those who may have done similar research, which would be considered secondary data for accuracy.
Research and the scientific method are key components in developing statistics using primary and secondary data through experiments.  Researchers rely on statistics when conducting experiments to help them decide whether the results from their experiments are true or false and that is what makes statistics an important factor in research when conducting experiments.
