An experiment found a significant difference between boys and girls pertaining to their
ability to identify objects held in their left hands, which are controlled by the right side of
their brains, versus their right hands, which are controlled by the left side of their brains.
The TI Graphics team conducted a similar test for adult men and women.
The test involved 30 small objects, which participants were not allowed to see. First, they
held 15 of the objects one by one in their left hands and guessed what they were. Then
they held the other 15 objects one by one in their right hands and guessed what they
were. Use box plots to compare visually the correct-guess data from this table.
Each row in the table represents the results observed for one subject. Note that 10
women and 12 men were tested.
