The Pearson correlation coefficient is a measure of the
linear relationship between two variables. It ranges from -1 to 1, where 1
indicates a perfect positive linear relationship, -1 indicates a perfect
negative linear relationship, and 0 indicates no linear relationship. The main connections game difference between
correlation and Pearson correlation is that the Pearson correlation
specifically measures the strength and direction of the linear relationship
between two variables, while correlation in general can refer to various
measures of association between variables that may not be limited to linear
relationships. I hope this explanation helps clarify the difference and
application of these concepts.
