correlation coefficient calculator, formula, tabular method, step by step calculation to measure the degree of dependence or linear correlation between two random samples X and Y or two sets of population data, along with real world and practice problems
Correlation coefficient measures the degree to which two variables move together. Its value ranges between -1 and 1. -1 indicates perfectly negative relationship, 1 shows a perfectly positive relationship and zero means there is no linear relationship be
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...
From the example above, it is evident that the Pearson correlation coefficient, r, tries to find out two things – the strength and the direction of the relationship from the given sample sizes.
