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
To check that, we have to do a correlation analysis. This is the formula to calculate the Pearson correlation coefficient The above formula is too complex to calculate the correlation coefficient. You have to do many complex calculations to get the final answer. Isn’t it a headache for you?
A correlation coefficient, r, is a number between -1 and 1 to measure the relationship between two variables. The sign of r (positive or negative) indicates the direction. If it is positive, both variables increase or decrease together. If it is negative, one variable increases while another...

The correlation coefficient is a value that indicates the strength of the relationship between variables. The coefficient can take any values from -1 to 1. The interpretations of the values are: -1:Perfect negative correlation. The variables tend to move in opposite directions (i.e., when one...
The correlation coefficient is a statistical calculation that is used to examine the relationship between two sets of data. The value of the correlation coefficient tells us about the strength and the nature of the relationship. Correlation coefficient v

1. There are two ways to report p values. The first way is to cite the alpha value as in the second example above. The second way, very much the preferred way in the age of computer aided calculations (and the way recommended by the APA), is to report the exact p value (as in ...
