Laterality Quotient

Measure of hand preference constructed by subtracting the number of tasks in which the left hand is dominant from those in which the right is dominant, dividing by the total number of tasks, and multiplying by 100. A score of 100 indicates complete dextrality; a score of 100 indicates complete sinistrality. About 85% of all people are dextral (right-handed).
