A case study can be defined as “an intensive description and analysis of a specific group.” (Christensen, 2013). In a case study, one person is extensively …show more content…
(McGavran & Lowe, 2007). In a correlational study, two or more variables are compared to each other to see if they relate in any way. For example, in a correlational study about the effect of vitamin J on memory, people who have and have not taken the drug would be surveyed using a questionnaire along with a test. The results of these surveys would be compared to who has taken the drug, and a general idea about the relationship between memory and vitamin J would be formed. Researchers are able to see whether or not a correlation exists between these variables, however, they cannot manipulate them. This makes it easy to obtain a vast amount of information about a subject that cannot be studied using an experiment. (Cherry, n.d.). Correlational studies are important because they can be used to collect a vast amount of information. In addition, they make it easy to study the relationship between a wide range of variables. (Crane & Hannibal, 2012). Correlational research also can be used to study variables not easily produced in a lab. (Crane & Hannibal, 2012). This research method is a tremendously good way to study the interrelations of variables, however, correlation does not indicate causation in many cases. Also, similarly to case studies, it is impossible to determine cause-and-effect through a correlational study. Because of this, only a prediction about certain behavior can be …show more content…
