Boxplots for first and last-day average exposure levels. PM2.5, EC, OC levels by job title and all job-titles combined. The outer box lines represent the first and third quartiles, while the thick horizontal line in the box represents the median. The “whiskers” extend to the values of the sample within 1.5 IQR of the lower and upper quartiles, and values outside this range are represented as circles.
