Table 3 Test of homogeneity of variances between studied groups using Levene’s test.
| Dependent variable | Levene statistic | df1 | df2 | P value |
|---|---|---|---|---|
| SNA (in degrees) | 0.01 | 2 | 87 | 0.99 |
| SNB (in degrees) | 0.00 | 2 | 87 | 0.99 |
| ANB (in degrees) | 0.02 | 2 | 87 | 0.99 |
| SNMP (in degrees) | 0.02 | 2 | 87 | 0.98 |
| SNOP (in degrees) | 0.00 | 2 | 87 | 1.00 |
| U1NA (in mm) | 0.04 | 2 | 87 | 0.97 |
| U1NA (in degrees) | 0.03 | 2 | 87 | 0.97 |
| L1NB (in degrees) | 0.04 | 2 | 87 | 0.96 |
| L1NB (in mm) | 0.00 | 2 | 87 | 0.99 |
| U1L1 (in degrees) | 0.15 | 2 | 87 | 0.86 |
| SLINE (in degrees) | 0.02 | 2 | 87 | 0.98 |
| df – degree of freedom; p – probability; SNA (Sella – nasion – subspinale), SNB (sella – nasion – supramentale), ANB (subspinale – nasion – supramentale), SN – MP (sella – nasion with midpoint – porion), SNOP (sella nasion – orbitale porion); Dental – U1NA (upper incisor – nasion – subspinale), L1NB (lower incisor – nasion – supramentale), U1L1 (upper incisor – lower incisor); Soft tissue – S line. Statistical significance: if the probability ‘p’ value is equal to or less than 0.05 (p≤0.05); NS – not significant. | ||||
