Say, Mean, Matter

1
Say, Mean, Matter

• When asked to interpret a graph, you should ask
  yourself 3 very important questions.
• What does the graph SAY?
• What does the graph MEAN?
• Why does the data in the graph MATTER?

2
SAY

• This is a description of the data in the graph.
  You are not considering WHY anything happened.
  You are only describing trends that you see in
  the data. Make sure to use numbers (the actual
  data) in your description.
• Heart Rate What is your average resting heart
  rate? How does that compare to group members.
  How did your heart rate change in the other 4
  conditions? How about your group members?

3
MEAN

• This is your opinion of what the data in the
  graph is telling you. What conclusions can you
  make about the data. WHY do you think that the
  data changed or did not change.
• Heart Rate Why do we get a resting heart rate?
• Why do you think your heart rate changed from one
  activity to the next? Why do you think each group
  member had different rates?

4
MATTER

• This is where you put the results/data in the
  context of what you are learning about. What
  does the data mean in relation to what you
  already know. Does the data lead you to a new
  question you can test with an experiment?
• Heart Rate What does this data tell you about
  the way your cardiovascular system works? How
  does the cardiovascular system differ from one
  person to another? Does the cardiovascular
  system interact with any other systems in these
  experiments?
