WebAs much as the correlation coefficient is closer to +1 or -1, it indicates positive (+1) or negative (-1) correlation between the arrays. Positive correlation means that if the values in one array are increasing, the values in the other array increase as well. A correlation coefficient that is closer to 0, indicates no or weak correlation. Web1) Correlation coefficient remains in the same measurement as in which the two variables are. 2) The sign which correlations of coefficient have will always be the same as the variance. 3) The numerical value of correlation of coefficient will be in between -1 to + 1. It is known as real number value.
