Handedness is a vague term that does not have a fixed or agreed definition. Although the terms left and right are enough to define handedness in an ordinary disclosure, they do not suffice for scientific research. The scientific definition of handedness can be based on two theoretical assumptions. It can be defined as the hand that performs faster or more precisely on tasks or the hand that one prefers to use, regardless of performance. In a scientific study, it should be recognized that handedness is not a discrete variable, but a continuous one that can be expressed at various levels between strong left and strong right. There are four different types of handedness that include: left-handedness, right-handedness, mixed-handedness, and ambidexterity. Globally, roughly 12% of men and 10% of women are left-handed.
