Understanding Data - Scale Invariance

Now one may ask why am I nit picking these things. The first point obviously means our modes calculated with an approximated measurement aren't exactly absolute modes. This is because if suppose we assume that number of months in a year is not 12  but 10  then the age of a person  with the new year scale will be quite different from the previous scale. This means trees which were five years old could get bumped to six years. Such a rearrangement of data points could throw up a new mode.
