Make a small circle with your thumb and index finger. Hold the circle a full arm’s length away. Look through this circle and focus both eyes on an object some distance away. Shut one eye at a time. The eye through which the object remains in the circle is your dominant eye.

Survey 30 people about both their dominant eye and their dominant hand (right or left). Record your results in a table. Use the results to describe the association between eye and hand dominance.

Look for reports of medical studies in the media. If possible, display the data given in a table. Do the data seem to support the claims made in the report?
