Use the tape measure to measure the length of your ulna. (It is the longest bone in your forearm. Measure from the end of
the bone at your wrist to the end of your elbow bone.) Record the length of your ulna in the space below. Then use the
graph you constructed earlier to predict your height in cm. Use the tape to measure your actual height if you do not know it.

Ulna length ___cm

Predicted height ___ cm

Actual height ___ cm

Was the graph a good predictor of your height? How might it be made better?
