Absolutely not. The simplest way to demonstrate this is to consider a measure of agreement - disagreement. If we scored it so that "strongly agree" is 5 and "strongly disagree" is 1, we would get one value of the correlation. If we reverse-scored it, we would get exactly the same value, but with the opposite sign. The strength of the correlation is the same, but the direction of the relation has switched. Another consideration is the fact that the actual strength of the correlation is based on the square of its value. 0.20 squared is 0.04; 0.40 squared is 0.16. A correlation of 0.40 is four times as strong as a correlation of 0.20. But when you square something, you automatically lose the sign. The square of a negative number is positive. So by definition, correlations of the same size but different signs are equal in strength.

Can the correlation coefficient be represented as a percentage?
No, the correlation coefficient is a measure of the strength and direction of the linear relationship between two variables, and it ranges from -1 to 1. It cannot be represented as a percentage.
When do you use Pearson's r?
See related link. As stated in the link: In probability theory and statistics, correlation (often measured as a correlation coefficient) indicates the strength and direction of a linear relationship between two random variables
What Is a statistic that measures the strength of the relationship between two variables?
correlation
What is the purpose of using correlation analysis How might correlation analysis be used in business decisions or in strategy formulation and implementation?
The correlation analysis is use in research to measure and interpret the strength of a logistic relationship between variables.
What is a way to look at how one set of data is related to another is called?
A way to look at how one set of data is related to another is called correlation analysis. This statistical method assesses the strength and direction of the relationship between two variables, indicating whether they move together (positive correlation), move in opposite directions (negative correlation), or have no discernible relationship. Tools such as scatter plots and correlation coefficients, like Pearson's r, are commonly used to visualize and quantify these relationships.
