Software Engineering (SE) experiments are traditionally analyzed with statistical tests (e.g., t-tests, ANOVAs, etc.) that assume equally spread data across treatments (i.e., the homogeneity of variances  ...  We have studied the role of variance in mature experimental disciplines such as medicine. We illustrate the extent to which variance may inform on technology performance by means of simulation.  ...  Acknowledgments This research was developed with the support of the Spanish Ministry of Science and Innovation project TIN2014-60490-P.  ...
