What is handedness ?
Handedness is an unequal distribution of fine motor skills between the left and right hand.
A person more dexterous with the right hand is right-handed and one more skilled with the left is left-handed.
Right-handed people are common.
8-15% people are left-handed.
Mixed-handedness is usage of both hands. Example: a person writing with the left hand but throwing a ball with the right hand, effectively.
Ambidexterity is rare. Here a person is able to do any task equally with either hand.
