Test of homogeneity of the variance for the validity of analysis of variance
| Levene’s test statistic | df1 | df2 | P | |
|---|---|---|---|---|
| Master | 2.067 | 7 | 17 | 0.105 |
| Orange | 3.351 | 7 | 17 | 0.020 |
Note: P value is not significant (P > 0.05) implying that the groups are homogeneous/have equal variance. Therefore, the analysis of variance is valid.
Abbreviations: df, degrees of freedom; Master, IOLMaster®; Orange, ORange® Gen II.
