Comparing Test Results Using Box Plots
Problem
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.
