About Normality Distribution of Age in Patients with Diabetes Mellitus

Ioan GOLET, Mircea Miron JIVULESCU, Maria Anastasia JIVULESCU

Abstract


The age variable from a sample of patients with diabetes mellitus has been analyzed with the iteratively applied method of moving average. Graphically, we found a normal frequency distribution of patients’ age. We were concerned by confirming the normality distribution of age, due to its importance, since many statistical tests require the normality as a prerequisite. We tested the above graphical conclusion using a concordance test (Kolmogorov-Smirnov).
