The Pearson Correlation Measures The Degree. The Pearson correlation measures the degree and the direction of the linear relationship between two variables. Mar 22 2021 By extension the Pearson Correlation evaluates whether there is statistical evidence for a linear relationship among the same pairs of variables in the population represented by a population correlation coefficient ρ rho.
The Pearson product-moment correlation coefficient or simply the Pearson correlation coefficient or the Pearson coefficient correlation r determines the strength of the linear relationship between two variables. A the degree of relationship without regard to the form of the relationshipB the degree to which the relationship is consistently one directionalC the degree of linear relationshipD the degree of curvilinear relationship2. The stronger the association between the two variables the closer your answer will incline towards 1 or -1.
If the coefficient value lies between.
The population correlation coe cient is usually denoted by ˆ. In terms of the strength of relationship the value of the correlation coefficient varies between 1 and -1. A value of. 1 then it is said to be a strong correlation.
