Final answer:
The statement about positive correlations suggesting health benefits is false; correlation indicates a relationship between variables but not causation.
Step-by-step explanation:
The statement "According to the text, out of the common factors that have been proposed, two appear to have the most consensual and research support. They are the therapeutic relationship and positive expectations" is not directly related to the provided statement regarding positive correlation. In regards to the provided statement: "A positive correlation means there are health benefits to the variable under investigation", this is a False statement. A positive correlation indicates that as one variable increases, so does the other, or as one decreases, so does the other. However, this statistical relationship does not imply that there are health benefits, as correlation does not establish causation. There could be many variables correlated with health outcomes that do not necessarily cause improvements in health.
