What a positive correlation indicates?

A positive correlation indicates that as one variable increases, the other variable also tends to increase, and vice versa. This relationship suggests a direct link between the two variables, where higher values of one are associated with higher values of the other. For example, in a study, if the amount of study time is positively correlated with test scores, it implies that more study time generally leads to higher test scores. However, it's important to note that correlation does not imply causation; other factors may influence this relationship.
