However, such has not been the case since data collection in most cases deviates from the research questions into answering other concerns around the intended research questions. Notably, qualitative studies often try to control or minimize these extraneous variables so that the research can address specific or the intended research objects. In fact, such extraneous variable should be minimized as low as possible when conducting research on medical areas.This can only be attained by collecting right data from patients. The quality of data will determine the quality of health care services given to the patient. However, the post concentrated on the verbal data, but the data from the patient should include the physical examination and recorded family or historical data. Nonetheless, it rightfully posted that after treatment and discharge, there should be a follow-up Again, this must not only be done through phone calls but the patient should visit the medical facility for follow up examination. It is unfortunate to the post that this type of survey cannot control extraneous variables; however, if direct and physical contact is maintain to the patients during data collection, then extraneous variables can be minimized as possible.
