Since we are here (cdt), they could be the values that you find in the
records
for a given field. For instance, your records are variables observed on
your students and the field of interest could be the number of members
of their family. You could be interested in the Median family size *of
your
students*... You could be interested in other statistics as well, Mean,
std, etc. ...
