I think that around 60% of the school will be left over right hand and 40% right over left hand clasping

Variables: 10-14 years of age, Just naturally clasp their hands, Weather or not they have hurt on hand or the other, if they right with there left or right hand.

I will go from student to student asking them if there parents are right or left handed and then I will ask them to clasp there hands and write it down.
