ab: Summary: This paper considers the responses of 115 school students to two
problems based on information provided in two-way tables. In each case
the question asks if one of the variables involved depends on the
other. Contextual knowledge might suggest a dependent relationship in
both but in one problem the data show independence while in the other
the data imply an inverse relationship. A wide range of solution
strategies illustrates the cognitive complexity dealing with
information in two-way tables.
