In this study, relationship between Intelligence Quotients (IQ) and Grade Point Average (GPA), the correlation is very strong. Correlation is known to be a positive. The meaning of this correlation is the relationship between the Intelligence Quotients (IQ) and the Grade Point Average (GPA). This correlation implies that individual with high Intelligence Quotients (IQ) have a high Grade Point Average (GPA), in my opinion it does imply that the having a higher IQ means that you brain is Intelligence Quotients. This means you are smarter, therefore your GPA will be higher. This correlation by the information was giving to me, did not have enough information to tell if having a high IQ causes higher GPA. More evidence would have been needed to answer this question appropriate. Students who have metal impairment or other mental disabilities where not mention in this case study in order to determine if it would influence this relationship.
The connection between correlation and causation is according to text is the two characteristics co-vary, or vary together, does not resume that one necessary cause the other. Some of the factors that affect the size of this correlation are shapes of distribution, sample sizes, outliers, restriction of range, aggregate samples, ecological, inferences, random error of measurement, and correlations with third variables (Chen & Popovich, 2002). Correlation is a good predicting GPA for this test because it allows one to compare variables together on one chart.
