WebA negative correlation coefficient (r < 0) indicates a negative linear relationship, meaning that as X increases, Y tends to decrease, and vice versa. A correlation coefficient of 0 (r = 0) indicates no linear relationship between X and Y. The correlation coefficient can also provide information about the strength of the relationship. WebThe most common way to calculate the correlation coefficient (r) is by using technology, but using the formula can help us understand how r measures the direction and strength of …

WebThe correlation coefficient is a statistical measure that quantifies the relationship between two variables. It can take values between -1 and +1, with a value of 0 indicating no correlation, a value of -1 indicating a perfect negative correlation (i.e., as one variable increases, the other variable decreases), and a value of +1 indicating a ...
