From: Preliminary evaluation for quality of dimension lumber in four common softwoods in Mongolia
Correlation coefficients among lumber properties in the four softwood species. n, number of lumber; AD, air-dry density at testing; DMOE, dynamic Young’s modulus; MOE and MOR, modulus of elasticity and modulus of rupture adjusted to the values at 15% moisture content by the methods described in Japan Housing and Wood Technology Center [27]; r, correlation coefficients. Values in parentheses followed by correlation coefficients are p-values obtained by a test of no correlation
