Evaluation of a Simple Test for Determining Handedness
An analysis for handedness of 3,225 hand tracings submitted by the junior high school students from almost all the 48 states in continental United States was made. The results show that Mubin Syed's test predicts correctly about 74% of the time. But if one merely predicts everyone as right-handed, then one would be correct 89.3% of the time. It is possible that Mubin Syed's test is predicting correctly handedness rather than hand preference. However Mubin Syed's test shows promise in detecting left handed and ambixdextrous persons.
