👉 Correlation, in statistics, is a relationship between two variables that can be quantified. It measures the degree to which one variable changes in response to another variable, usually through statistical analysis or correlation tests. The correlation coefficient ranges from -1 (perfect negative correlation) to 1 (perfect positive correlation), with values closer to 0 indicating a strong negative correlation and values further away from 0 indicating a weak positive correlation. Correlation is often used as an indicator of the strength of a relationship
