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.
