Group Activity

Aim :
To find the percentage of the students in a group of students who write faster with their left or right hand.

Material Required:
Graph paper, geometry box

Procedure
Take a paper and a pen
Write a letter or a digit for 15 secs with your right hand
Repeat the same activity for same duration with left hand
Record the data.
Take the number of digits / letters written with right hand as x and the number of letter written by left hand as y.
Plot the co-ordinates (x,y) on the graph paper.
From the graph , count the number of points which are above and below the line y = x.

Observation
When x > y, students write faster with right hand.
When x < y, students write faster with left hand.


Result

Total No. Of students = ________

Number of students who write faster with right hand = ____________

Percentage of students who write faster with right hand = __________

Number of students who write faster with left hand = ____________

Percentage of students who write faster with left hand = _____________
