The standard deviation will be small, if the data is spread out over a large range of values. Since the absolute value of -1 is greater than the absolute value of 0.5, the correlation is a strong one, even though the value is lower. Stereotypes are a good example of illusory correlations. On the other hand, causation refers to an event being the cause of the second one.

In other words, it reflects how similar the measurements of two or more variables are across a dataset. If we multiply X by a positive number, and multiply Y by a negative number, then the correlation will change. It only reflects relationship between two variables but not the cause and effect relationships among them. An illusory correlation does not always mean inferring causation; it can also mean inferring a relationship between two variables when one does not exist. [TY9.7], 8. The general formula is rXY=COVXY/(SX SY), which is the covariance between the two variables, divided by the product of their standard deviations: In the cell in which you want the correlation coefficient to appear, enter =CORREL(A2:A7,B2:B7), where A2:A7 and B2:B7 are the variable lists to compare.
