...... do not notice relevant features—for example, if they treat probabilistic outcomes as single events rather than distributions (Konold, 1989)—then they will not understand what a statistical explanation is referring to. Furthermore, without an understanding of the relevant features, students may transfer in vague intuitions that do not have sufficient precision to motivate the form or function of a particular statistical formalization ( Mokros ......

...Moore (1990) has argued that in statistics, the context motivates procedures; data should be viewed as numbers with a context, and hence the context is the source of meaning and basis for interpretation of obtained results....

...really is, but as it might be reimagined This kind of reimagining is characteristic of mathematics (O'Cormm, 1998) It is this hypothetical, or 'abstract', quality of the arithmetic mean which causes much difficulty for students (Mokros and Russell, 1995) I had two reasons fOr wanting to fOcus the conversation on the meaning of the average....
