From: Thermal expansion of wood at different equilibrium moisture contents
Box plots of the coefficients of thermal expansion at 7.0 and 11.4% of moisture content. The black line inside the box is the median value, the upper and lower lines of the box are the first and third quartiles, the upper and lower lines are the maximum and the minimum values, and the notches are the 95% confidence interval of the medians
