Chapter 17: Activities 480
11. Compare the right-hand results. Define plot 1 to use WRGHT, define plot 2 to use
MRGHT, and then press r to examine minX, Q1, Med, Q3, and maxX for each plot.
Who were the better right-hand guessers?
In the original experiment boys did not guess as well with right hands, while girls
guessed equally well with either hand. This is not what our box plots show for adults.
Do you think that this is because adults have learned to adapt or because our
sample was not large enough?
