What is Correlation and Why Does It Matter? - dev
Correlation measures the strength and direction of a linear relationship between two variables on a scatterplot. The value of the correlation coefficient ranges from -1 to 1, with 1 indicating a perfect positive linear relationship and -1 indicating a perfect negative linear relationship. A correlation coefficient close to 0 suggests no linear relationship between the variables. While correlation does not imply causation, it can help identify potential relationships that may be worth investigating further.
