For this data set the correlation coefficient is 0988. Let z r ln1r 1-r 2. Correlation Coefficients Positive Negative Zero Which reflects the direction and strength of the linear relationship between the two variables x and y. . It returns a value between -1 and 1. It is tough to practically draw a line. Given the table-like structure of bounded intensities -1 1 - a natural and convenient way of visualizing the correlation coefficient is a heatmap. In some kind of situation or studies with two or more raters or judges Intraclass Correlation Coefficient can be also used for test-retest repeated measures of the same subject and intra-rater multiple scores from the same raters reliability analysis. A correlation of -10 shows a perfect negative correlation while a correlation of 10 shows a perfect positive correlation. R sumX barXY barYoversqrtsumX.
