Description To investigate the effect of drying of beech wood on the humidity percentage, the following experiment was conducted. Each of 20 planks was dried in a certain period of time. Then the humidity percentage was measured in 5 debths (1,3,5,7,9) and 3 widths (1,2,3) for each plank: debth 1: close to the top debth 5: in the center debth 9: close to the bottom debth 3: between 1 and 5 debth 7: between 5 and 9 width 1: close to the side width 3: in the center width 2: between 1 and 3 Number of observations: 300 (20 planks) Variable                Description plank Numbered 1-20 width Numbered 1,2,3 debth Numbered 1,3,5,7,9 humidity Humidity percentage Source The Royal Veterinary and Agricultural University, Denmark.
