This result iscoherent with boxplots presented in the data explorationbecause these categories also have a different characteristicconcerning coupling metrics.For Test II, Table IV shows, for each metric, the meanvalue and standard deviation considering all classes fromprojects of the same category. For each metric, the highestvalues were marked with `>´, while the lowest values weremarked with `6.652.36>3.760.82>1.613.17>5.326.91>15.98Development1.62
