A correlation coefficient of .90 indicates a strong positive relationship between two variables.
<h3>What is a correlation coefficient?</h3>
A correlation coefficient is a metric that expresses a correlation, or a statistical link between two variables, in numerical terms. Two columns of a given data set of observations, also known as a sample, or two parts of a multivariate random variable with a known distribution may serve as the variables.
Variables with correlation coefficients between 0.9 and 1.0 in magnitude are thought to be very highly correlated. Variables that can be regarded as having a high degree of correlation are indicated by correlation coefficients with magnitudes between 0.7 and 0.9.
