Correlation value of 0
WebJan 25, 2024 · The degree of correlation is expressed by the value of \(r\). If \(r=+1\), the variables are highly positively correlated. If the value is \(-1\), the variables are highly correlated or have a perfect negative correlation, and if the value is \(0\), there is no correlation between the variables. Frequently Asked Questions (FAQs) Q.1. The correlation coefficient ranges from −1 to 1. An absolute value of exactly 1 implies that a linear equation describes the relationship between X and Y perfectly, with all data points lying on a line. The correlation sign is determined by the regression slope: a value of +1 implies that all data points lie on a line for which Y increases as X increases, and vice versa for −1. A value of 0 implies t…
