Box-and-Whisker Plot of serological titers of pigs over time using three commercial ELISA kits and a virus neutralization assay. A box represents the middle 50% of the data values. The continuous horizontal line within the box is the sample median. Plus indicates sample mean. Whiskers indicate the largest and smallest values. “Outside points” indicate values that are more than 1.5 times the interquartile range above or below the limits of the box. Discontinuous lines represent the positive threshold. ch = challenge; sl = slaughter
