On a scale measuring the strength of correlation, what does a value of 0.2 represent?

A correlation value of 0.2 indicates a low correlation between two variables. In the context of correlation coefficients, values range from -1 to +1. A value of 0 implies no correlation, while values closer to -1 or +1 indicate stronger relationships. Specifically, a correlation of 0.2 suggests a weak positive relationship; as one variable increases, the other variable tends to increase slightly, but this tendency is not strong.

Understanding correlation values helps in interpreting the strength and direction of relationships in various fields, including kinesiology, where assessing relationships between physical activities and health outcomes is crucial. A low correlation does suggest some level of association, but it typically means that other factors may also significantly impact the relationship being evaluated.
