  1. Line Graph Project By HarleenSuri, Eliza Neights, Carina Tse

  2. What is a Line Graph? • Graph used to represent data with an independent and dependent variable when showing changes over time • Data is plotted on the graph and connected with lines

  3. When is it Used? • When you are showing changes over time

  4. Real World Example • The graph shows the temperature (°F) of New York City over 6 days • Can easily see trend of data • Could be used by meteorologists

  5. What Type of Data Do You Need? • Set of data- Can be a single or multiple or single set • Need key if using multiple sets of data

  6. Data Collected

  7. How We Made the Graph • Draw and label a x- axis and y- axis • Create a scale on each axis • Plot your data points • Connect each point with line segments • Give your graph a title

  8. Quiz Question A TV company wants to schedule commercials during the day kids watch the most amount of TV. Mrs. Ellwood’s class was selected to complete a survey based on how much TV they watch. Find the largest increase in time TV was watched. Then, find the percent of increase of time TV was watched.

  9. How to Solve • Find the largest increase in the graph. • From Friday to Saturday, the increase in time was greatest • Then find percent of increase to the nearest tenth 83-52 52 Difference Original = ≈ 59.6%

  10. Advantages of Line Graphs • Can visually see the trend of the data • Can see how data increases/decreases • Can compare two sets of data • Use a line graph with multiple sets of data

  11. Disadvantages of Line Graphs • Hard to see the specific data points when the scale is large • Sometimes the scale can change the appearance of the data
