Explanation:
Detailed explanation-1: -The most commonly used correlation coefficient is the Pearson coefficient, which ranges from-1.0 to +1.0. A positive correlation indicates two variables that tend to move in the same direction. A negative correlation indicates two variables that tend to move in opposite directions.
Detailed explanation-2: -A positive correlation means that the variables move in the same direction. Put another way, it means that as one variable increases so does the other, and conversely, when one variable decreases so does the other. A negative correlation means that the variables move in opposite directions.
