Final answer:
The statement regarding primary data from patient health records and secondary data from indexes is true. Primary data is directly collected original data, while secondary data has been collected by others previously. Positive correlation merely indicates a direct relationship, not necessarily health benefits.
Step-by-step explanation:
True or False: Primary data comes from the patient's health record and secondary data comes from indexes. This statement is true. Primary data is data collected directly from the source such as patient health records, observations, or through experiments. It is the original data that has been collected specifically for the purpose of the study at hand. Secondary data, on the other hand, refers to the data that has already been collected and processed by others. This includes information from indexes, databases, and infographics such as those mentioned as being secondary sources in the reference provided.
One of the advantages of secondary data like old movies or WHO statistics is that it is nonreactive research (or unobtrusive research). This type of research does not involve direct contact with subjects and will not alter or influence people's behaviors. Thus, data from these sources is often considered stable and consistent, as it does not encounter the risk of altering subject behavior through the research process itself.
As for the correlation subject mentioned, it is important to clarfiy that a positive correlation does not necessarily imply health benefits. It simply indicates a direct relationship where two variables move in the same direction, but this does not establish causation nor does it denote that the relationship is beneficial or harmful.
