Advanced Air Quality

Study the three images in Figure 7.5 in your textbook, and then consider the authors' comments regarding accuracy, precision, and bias on pages 248-251. Notice that the reported industry practice is to accept sample data within 10% of the true value for statistical sampling methods and within 25% of the true value for passive sampling methods.
What problems do you think that this practice could pose when attempting to generalize air quality study outcomes?
