iii. The correlation coefficient is bound by –1 and +1. The closer the coefficient to –1 or +1, the stronger is the correlation. iv. With the exception of the extremes (that is, r = 1.0 or r = -1), we cannot really talk about the strength of a relationship indicated by the correlation coefficient without a …

How to Calculate Pearson Correlation Coefficient: 9 Steps
A correlation coefficient formula is used to determine the relationship strength between 2 continuous variables. The formula was developed by British statistician Karl Pearson in the 1890s, which is why the value is called the Pearson correlation coefficient (r). The equation was derived from an idea proposed by statistician and sociologist Sir ...
