Answer: The correlation coefficient is a statistical indicator of the strength of the association here between relative movements of two variables. The values are in the -1.0 to 1.0 range. If the projected value was more significant than 1.0 or smaller than -1.0, there was a measurement error in the correlation. A perfect negative correlation is shown by a correlation of -1.0, and a perfect positive correlation is indicated by a correlation of 1.0. A correlation of 0.0 shows that there is no linear relationship between the changes in the two variables.
