Box Plot from Scientific Research

Voltage magnitudes (V) required to lift dead ticks across a 2.5 mm air gap against gravity for both positive and negative voltages. n = 12 for each group. Midline of boxplots is the median, edges of boxes are the first and third quartiles, and whiskers are the minimum and maximum, defined by the first and third quartiles +- 1.5 x interquartile range.
