Classification of the coefficients of variation for sugarcane crops
The objective of this paper was to evaluate the range of classification of variation coefficient in experiments with sugarcane. For this study, some of the variables that are mostly used by researchers of the culture were considered. The data was obtained after extensive bibliographical revision from scientific journals, data base from the improvement program of sugarcane from the Federal University of Viçosa, master dissertations, doctorate thesis and technical reports. Classification ranges were proposed according to the Costa method, in which is based the use of a median and pseudo-sigma. The variables tons of stalks per hectare and tons of pol per hectare presented the highest ranges of the classification of the coefficients of variation, while the variable percentage of sucrose presented the lowest range. All of the variables presented specific ranges of classification, showing the need to consider, in the classification of coefficients of variation, the nature of the variable being studied.
