We will include an explanation of positive, negative, or zero correlation, explaining what the number signifies and supplying examples. Explain how a non-linear relationship among two variables can influence the correlation coefficient, what happens to the size and the sign of the correlation coefficient if we correlate the two variables. Lastly, we will discuss the floor and ceiling effect; how these issues can preclude a significant correlation coefficient from being discovered. Correlational research is conducted when researchers want to assess relationships among naturally occurring variables, mostly done using the survey research approach; examples of natural occurring variables are but not limited to, height, weight, athletic ability, grades, moral values, attitudes, preferences, and personality characteristics (Zechmeister, Zechmeister, & Shaughnessy, 2001).
