| Real root | Virtual root | t test | ||||
|---|---|---|---|---|---|---|
| n | xav ± SD | n | xav ± SD | t-value | P | |
| Ratio | 31 | 1.25 ± 0.12 | 31 | 1.21 ± 0.07 | 1.81 | 0.07 |
The samples were dependent and every ratio of the virtual apex was paired with corresponding ratio in the real apex
n number of walls, x av mean value, SD standard deviation
