Subject: Graphing

When elementary students graph data by placing a marble at various
points on a ramp (i.e.10 cm, 15 cm, and 20 cm from the bottom of the
ramp) and then measuring the distance it pushes a half paper cup, is
this considered discrete data or continuous data?  The directions for
this activity say the students can graph the data on a bar graph and
then make predictions for distances not measured directly.  Is this
accurate?  What constitutes discrete data from continuous data.  I am
aware of the basic definitions for both of these types of data.  Are
the directions for graphing this activity on a bar graph correct?
