Correlation

Question One

The correlation indicates there might be an association between a family’s income and

SAT scores. Notably, the correlation will offer insight into the direction of the association

between the two variables. For instance, does an increase in family income result in a rise in

SAT scores? If there is a strong positive correlation, then after knowing one value, it is possible

to predict the next one.

Question Two

The correlation does not provide evidence that having a high income results in higher

SAT scores. In statistics, having a correlation should not be taken to mean there is causality

(TEDx Talks, 2012). It is possible there is a third factor affecting the two variables and hence

creates a perception that they impact each other. Therefore, it is probable to have a student from

a high-income family who gets low SAT scores.

Question Three

Similarly, it does not imply that getting higher SAT scores will result in increased

income. There is no irrefutable evidence that can be used to support such an assertion. In some

cases, it is possible to note a correlation between two variables and immediately jump to the

conclusion that there is causality. However, there is a need to carry out further research to

ascertain that there are no additional factors that are causing the correlation.

Question Four

In statistics, correlation should not be taken to imply two variables affect each other

(CrashCourse, 2018). Therefore, just because one notes a relationship between two variables, it

does not mean that one leads to the other. While there is a possibility of one variable causing the
