Researchers must do what they can to gather unbiased data. For instance, it has been shown that when blood pressure is taken using the finger cuff, it helps to massage the muscles in the hand first. This action helps correct the flaw in the design of the data-gathering process and minimizes the measurement/response bias. The researchers who want to estimate the mean blood pressure of adults are now massaging patients' hands first, but they have discovered another problem. Some members of their representative sample work long hours at their jobs and are too busy to come in for the blood pressure measurements. How might this influence the results of the study?
