What does a positive correlation between two variables indicate?

A positive correlation between two variables indicates that as one variable increases, the other variable also increases. This relationship emphasizes that both variables tend to move in the same direction. For example, if you are looking at the relationship between hours studied and exam scores, a positive correlation would imply that more hours studied are associated with higher exam scores.

In research and data analysis, identifying a positive correlation helps in understanding how two factors might be related, indicating a direct association that could be significant in various fields such as psychology, health sciences, and more. Essentially, a positive correlation provides insights into behaviors and trends that can aid in further investigations or decision-making.
