CORRELATIONAL RESEARCH Correlational Research in Psychology LeighAnn Hancock Kaplan University PS300-Research Method I Professor Myeisha Leiva October 2, 2012 Correlational Research in Psychology Psychologists employ a number of different scientific methods to conduct research on social psychology topics. Employing these methods allows researchers to test hypotheses and theories by looking for relationships between different variables. Social psychologists use correlational research in order to identify relationships between naturally occurring variables. Conducting surveys is a popular method for researchers to use to gather data needed for a correlational study. Surveys allow researchers to predict and describe people’s opinions, attitudes and preferences by computing a correlation coefficient and determining the strength and direction of the relationship between the two naturally occurring variables. The correlation coefficient does not reflect nonlinear relationships between variables. If a relationship between two variables is not linear, then the correlation coefficient will be of little use. Correlation study produces three possible results: a positive correlation, a negative correlation, and no correlation, also referred to as zero correlation. A visual representation of the data can be made on a scatter gram/plot and a linear relationship exists when the graph showing the relationships between the two variables results in a straight line, or something very near a straight line. Correlational research is employed when studying variables that cannot be manipulated, such as birth order, sex, and age, and therefore scientific knowledge concerning them must be based on correlation evidence. Researchers must remember to keep in mind avoiding the floor and ceiling effect when conducting correlational research as well as acknowledging that correlation
