Example 1: Using cor() Function to Calculate Pearson CorrelationIn this example, I’ll illustrate how to apply the cor function to compute the Pearson correlation coefficient.Have a look at the following R code and its output:cor(x, y) # Pearson correlation # [1] 0.63733...
If the correlation coefficient is +1, two variables have a perfect positive correlation. If the correlation coefficient is -1, two variables have a perfect negative correlation. Variables are strongly correlated when the correlation coefficients are near +1 or -1. If it is near zero, the correl...
A correlation coefficient is a value that tells you how closely two data series are related. A commonly used example is the weight and height of 10 people in a group. If we calculate the correlation coefficient for the height and weight data for these people, we will get a value between ...

Thecorrelation coefficientmeasures the association between two variables. Correlations are shown as values between -1.0 and 1.0, from negative correlation to positive correlation. In other words, there is less correlation with a number closer to 0 and a higher correlation as you get closer to 1....
The table below summarizes the other calculations needed forr. The sum of the products in the rightmost column is 2.969848. Since there are a total of four points and 4 – 1 = 3, we divide the sum of the products by 3. This gives us a correlation coefficient ofr= 2.969848/3 = ...
