| dc.description | The present work discusses the need of testing variance homogeneity of data as a first step for performingstatistical analysis of ethylene production by harvested peaches. Variance homogeneity is one of the basicassumptions in analysis of variance (ANOVA) and then, any departure from this assumption, should be correctedby a mathematical transformation of data. Ethylene production was analyzed by gas chromatography in individualfruits by using a static system. Graphics of individual residues vs. treatment means were accomplished with nontransformedand logarithmic transformed data. Results showed an evident absence of variance homogeneity,being this failure adequately stabilized by logarithmic transformation as analyzed by Barlett test. Analysis ofvariance (ANOVA) was also done with both kinds of data, which showed the suitability of logarithmictransformation in increasing the experiment capability to demonstrate significant differences among treatments.Least Significant Difference (LSD) test was used to compare means. This test showed misinterpretations thatcould arise if this kind of analysis were not performed | |
