When discussing correlation, what does the term "strength" refer to?

The term "strength" in the context of correlation specifically refers to the magnitude of the relationship between two variables. This means that it quantifies how closely the two variables are related to each other, which can be represented through a correlation coefficient ranging from -1 to +1. A correlation coefficient closer to -1 or +1 indicates a strong relationship, whereas a value near 0 signifies a weaker relationship.

In practical terms, when analyzing data, understanding the strength of the correlation helps determine how much one variable can predict or explain variations in another. A strong correlation suggests that changes in one variable are closely associated with changes in the other, making it an important factor when interpreting data and making predictions based on that data.
