Table 1 Results of Pearson correlation analysis (n = 90)

From: An experimental study on change of gas permeability depending on pore structures in three species (hinoki, Douglas fir, and hemlock) of softwood

  Y X1 X2 X3
Y 0.709** 0.178 − 0.258*
X1   0.113 0.252*
X2    − 0.188
  1. * and ** represent significance at 5 and 1 percent levels, respectively. Denotations of variables are as follows:
  2. Y gas permeability, X1 through pore porosity, X2 mean pore size, X3 bulk density
