should go beyond creating graphs and computing averages to include making decisions about what kinds of computations or visual representations are appropriate in a given situation.

Presenting the task: The teacher should provide a short introduction to the subject matter of the assessment task — two kinds of bears that live in the Rocky Mountains of Montana. Rangers and biologists sometimes collect data on samples of bears. The task is to analyze two lists of data from individual grizzly bears and black bears.

As always, pencils, rulers, graph paper, calculators, etc., should be available.
