Descriptive Statistics were used with average, error-standard, median, standard deviation, minimum and maximum and absolute delt. The normality of the sample was evaluated by the test by Shapiro-Wilk (GC) and by Kolmogorov Smirnov (GE). To analyze the answer variables, comparisons were made between groups, t-student test couplet or by Wilcoxon, when appropriate (homogeneous or heterogenous distributions of the data, respectively). To make evaluations between groups the parametric test by ANOVA was used in two ways, followed by Post Hoc de Scheffe. The study used the level of p < 0.05 to test the statistical significance. The results were evaluated by Excel and the Statistical Package for the Social Science® (SPSS), version 14.0.
