Just as scientific fields, such as biology, are interested in defining and explaining the mechanisms of certain behavior, many fields of psychology are interested in determining the relationships of interesting phenomena correlates of this world. In this experiment, we will examine an individual's amount of sleep and their information retention using correlational study and experimental research techniques. A correlational study tests statistical relationships between variables or events that may have a relationship with each other. In this study, we will examine the statistical relationship between an individual's amount of sleep and their information retention. Like many scientific techniques, correlational research is not a foolproof method, but it has its own problems, such as the directionality problem and the third variable problem. The directionality problem denotes the fact that the variable M and the variable N will be statistically correlated if M causes N, or if N causes M. The directionality problem is demonstrated in this correlational study as the quantity of one...
