Example of statistical evaluation
Distribution of the electrical conductivity EC (µS/cm) in the hydrogeochemical unit "Berlin-Brandenburger Jungpleistozän". The steep section of the upper anomaly can clearly be identified while the slope of the lower anomaly is not fundamentally different from that of the normal distribution. The values between 100 and 1280 µS/cm were included to calculate the background value (90%-percentile).
