  2. Vocabulary Define the following words on your vocabulary sheet: Line Graph Trend Deviations You will have 5 mins alone and then 5 mins with your elbow partner.
  3. Pictogram A pictogram is a type of bar graph that uses pictures instead of bars to represent the data being looked at. Why would a pictogram be misleading? Look at the picture on page 209 and talk to your elbow partner about why this graph could be misleading.
  4. Line Graphs Evaluate when to use a line graph instead of a pie chart or bar graph. What can we infer about a line graph and its data points? Review what makes a good graph.
  5. Practice Problems Page 214 Problems number 4.6 and 4.7 need to be answered in complete, thoughtful sentences. When everyone finishes we will discuss the answers. You will keep these problems in your notes to use to study and review.
  6. Practice problems and their answers Problem 7 The graph does not fairly represent the data. The area of each CD is more than the percent increase. Problem 6 The graph is not a correct comparison because the differences between the interest rates seems to be much larger than they really are.
