Final answer:
A positive correlation does not necessarily indicate health benefits; it simply reflects a relationship where variables move in the same direction, which could be beneficial or harmful.
Step-by-step explanation:
False. A positive correlation between two variables simply means that as one variable increases, the other variable tends to increase as well, or as one decreases, the other follows. However, this does not inherently suggest that there are health benefits to the variable under investigation. A positive correlation in health studies could indicate a beneficial relationship, such as exercise and improved heart health, but it could also represent a harmful connection, like the relationship between smoking and lung cancer. Therefore, the presence of a positive correlation in and of itself does not determine the healthfulness of a variable; further research is needed to understand the nature of the relationship and its implications on health.
