Correlation is a statistical measure that expresses the extent to which two variables are linearly related. It quantifies the degree to which changes in one variable predict changes in another. Here’s a detailed introduction to understanding correlation:
Interpreting Correlation Coefficients
0.9 to 1.0 (or -0.9 to -1.0): Very high correlation
0.7 to 0.9 (or -0.7 to -0.9): High correlation
0.5 to 0.7 (or -0.5 to -0.7): Moderate correlation
0.3 to 0.5 (or -0.3 to -0.5): Low correlation
0.0 to 0.3 (or -0.0 to -0.3): Very low correlation
Understanding correlation is foundational in statistics and data analysis, providing insights into relationships between variables and guiding further investigations into causative factors.
