Process engineer has applied … WebJul 8, 2024 · Correlation values, most commonly used as Pearson's r, range from -1 −1 to +1 +1 and can be categorized into negative correlation ( -1 \lt r \lt 0 −1 < r < 0 ), positive …
WebHow to Interpret Correlation and R-Squared. Once you've calculated correlation and R-squared, you need to interpret the results. Here are some guidelines: A strong positive or negative correlation (i.e. a value close to +1 or -1) indicates a strong relationship between the variables. A weak positive or negative correlation (i.e. a value close ...
WebPearson's r measures the linear relationship between two variables, say X and Y. A correlation of 1 indicates the data points perfectly lie on a line for which Y increases as X increases.
