A correlation coefficient, usually denoted by rXY r X Y, measures how close a set of data points is to being linear. In other words, it measures the degree of dependence or linear correlation (statistical relationship) between two random samples or two sets of population data. The correlation coefficient uses values between −1 − 1 and 1 1.

Step 3: Calculate! Once you have your data in, you will now go to [STAT] and then the CALC menu up top. Finally, select 4:LinReg and press enter. That’s it! You’re are done! Now you can simply read off the correlation coefficient right from the screen (its r). Remember, if r doesn’t show on your calculator, then diagnostics need to be ...

The correlation coefficient is a measure of how well a line can describe the relationship between X and Y. R is always going to be greater than or equal to negative one and less than or equal to one. If R is positive one, it means that an upwards sloping line can completely describe the relationship. If R is negative one, it means a downwards ...

Pearson Correlation Coefficient Calculator. The Pearson correlation coefficient is used to measure the strength of a linear association between two variables, where the value r = 1 means a perfect positive correlation and the value r = -1 means a perfect negataive correlation. So, for example, you could use this test to find out whether people's height and weight are correlated …
