2.6 Statistical analysis
Data collected from the determination were subjected to one-way analysis
of variance (ANOVA) to analyze differences in the tested parameters
using SPSS 19.0 (SPSS Inc., Chicago, USA). The Duncan’s Multiple Range
Test (DMRT) at a 5% level of significance was used to test significance
of differences between means when F-values were significant. Simple
regress analysis was used to quantify the relationships among the
response variables. Prior to analysis, data were tested for homogeneity
of variance and normality. Figure was accomplished with SigmaPlot 12.0
(Systat Software Inc., London, UK).
