 Using the average ratios of foot length to hand span, calculate
the hand span of Shaquille O'Neal.
 Using graph paper, graph the foot length and hand span information
from your table.
 Extend the axis for foot length to include Shaquille O'Neal's 41
cm foot.
 Draw a line of best fit for the graphed data.
 Locate the foot length and corresponding hand span for Shaquille
O'Neal on the line.
As a result of this activity,
students will learn how to collect, graph, and extrapolate data.
Students can extend this
activity by using a graphing calculator or a computer spreadsheet
program. The student can use both ways to graph and then make predictions
about the size of Shaq's hand span.
