what percentage of the world population is right-handed
Handedness In human biology, handedness is a better, faster, or more precise performance or individual preference for use of a hand, known as the dominant hand; the less capable or less preferred hand is called the non-dominant hand.[1][2][3] Men are somewhat more likely to express a strongly dominant left hand than women.[4] It is estimated that between 70 and 95 percent of the world's population is right-handed.
