What is a Correlation Coefficient? The r Value in ...

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. A value of -1 also implies the data points lie on a line; however, Y decreases as X increases. The formula for r is. WebAs an illustration, the Pearson correlation between horsepower ( hp ) and miles per gallon ( mpg ) found above is -0.78, meaning that the 2 variables vary in opposite direction. This makes sense, cars with more horsepower tend to consume more fuel (and thus have a lower millage par gallon). elworth flower club https://roschi.net
