Implement fields for typical StatisticalMeasurementValues
To simplify the handling of quantitative data we may want to add concrete fields for min, max, average, sampleSize, typicalLowerBoundary, typicalUpperBoundary, variance, standardDeviation.
Maybe we also want singleValue (instead of average and sampleSize = 1
Only modifiers will not be available anymore. Are they needed? If yes, do we need them for each field or for

One problem that arises is the correct use of numbers in Java, Hibernate + DB. For correct rounding etc. we should better use BigDecimal rather than Double.

Alternatively we may use UserType with String representation !! But this may not allow Database computations on values.
