Analysis:
 Average
data – round to nearest tenth.
 Make a line graph – use graph paper; put
the MV on the X-axis (horizontal) and the
RV on the Y-axis (vertical). Include labels
and scales (use equal intervals) on each
axis. Include a title.
Conclusion:
•
•
•
•
Does the data support the hypothesis?
Answer the question using the data.
