Why it’s important to understand that correlations may be spurious?
Spurious correlations can occur in statistics when two or more variables appear to have a cause-and-effect relationship with one another. Additionally, spurious correlations can give you a better understanding into the characteristics and behaviors of a data set.
What is an spurious relationship?
Spurious is a term used to describe a statistical relationship between two variables that would, at first glance, appear to be causally related, but upon closer examination, only appear so by coincidence or due to the role of a third, intermediary variable. When this occurs, the two original variables are said to have a “spurious relationship.”
