ab: Summary: Statistical reasoning focuses on properties that belong not to
individual data values but to the entire aggregate. We analyze
studentsâ€™ statements from three different sources to explore possible
building blocks of the idea of data as aggregate and speculate on how
young students go about putting these ideas together. We identify four
general perspectives that students use in working with data, which in
addition to an aggregate perspective include regarding data as
pointers, as case values, and as classifiers. Some students seem
inclined to view data from only one of these three alternative
perspectives, which then influences the types of questions they ask,
the data representations they generate or prefer, the interpretations
they give to notions such as the average, and the conclusions they draw
from the data.
