The typical terms "Symmetric as well as Normal" in Statistics require some classification, at least, including arithmetically symmetric and/or normal, geometrically symmetric and/or normal, or harmonically symmetric and/or normal. Tests for classifying the pattern and symmetricity and/or normality of the data; finding proper location and other characteristics, Box-plots, cut off points; outlier(s) detection criteria, criticism of the calculations of the location of the existing probability distributions, etc have been developed.
