  1. Constructing Graphs

  2. ~Line Plots~

  3. Making a Line Plot • Collect data and put in chronological order Ex. Scores on a math test 63 68 72 74 79 80 80 83 84 84 84 85 88 90 90 90 90 93 95 95 95 97 • Determine a scale and intervals • If you have a small range, you should probably use intervals of 1 • With larger scales, it is best to mark intervals every 2, 5, or 10 numbers.

  4. Making a Line Plot • Draw a horizontal line and mark the intervals. Ex. Scores on a math test 63 68 72 74 79 80 80 83 84 84 84 85 88 90 90 90 90 93 95 95 95 97 60 65 70 75 80 85 90 95 100

  5. Making a Line Plot • Mark an X above the number for each data point. • If a number is repeated, place one X above the other. Ex. Scores on a math test 63 68 72 74 79 80 80 83 84 84 84 85 88 90 90 90 90 93 95 95 95 97 X X X X X X X X X X X X X X X X X X X X X 60 65 70 75 80 85 90 95 100

  6. Making a Line Plot • Count the number of data points and count the number of X’s to make sure you plotted each point! Ex. Scores on a math test 63 68 72 74 79 80 80 83 84 84 84 85 88 90 90 90 90 93 95 95 95 97 X X X X X X X X X X X X X X X X X X X X X 60 65 70 75 80 85 90 95 100

  7. You Try! • There are 31 days in August, and here are the temperatures for that month: August 69 70 71 71 72 72 72 73 74 75 75 76 76 76 77 77 77 77 77 78 78 80 81 82 82 83 83 85 85 90 93 X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X 65 70 75 80 85 90 95

  8. ~Stem and Leaf Plots~

  9. Here are one student’s math test scores. Make a stem-and-leaf plot for this data. First, draw the dividing lines.

  10. Here are one student’s math test scores. Make a stem-and-leaf plot for this data. Next, label the stem side and the leaf side. Stems Leaves

  11. Here are one student’s math test scores. Make a stem-and-leaf plot for this data. Find the smallest piece of data and plot it on the grid. Stems Leaves 7 5

  12. The 7 for the tens place is already there. We just add the 9. Here are one student’s math test scores. Make a stem-and-leaf plot for this data. Stems Leaves 9 7 5 Find the next smallest piece of data and plot it on the grid.

  13. Continue with this process until you have entered all the data. Stems Leaves 7 5 9 8 3 4 6 6 8 9 1 4 9

  14. Remember to add a title. Test Scores Stems Leaves 7 5 9 8 3 4 6 6 8 9 1 4 9

  15. Don’t forget the key! Test Scores Stems Leaves 7 5 9 8 3 4 6 6 8 9 1 4 9 Key: 7 5 means 75

  16. You Try! • There are 31 days in August, and here are the temperatures for that month: August 69 70 71 71 72 72 72 73 74 75 75 76 76 76 77 77 77 77 77 78 78 80 81 82 82 83 83 85 85 90 93 Temperatures for August Stems Leaves 6 9 7 0 1 1 2 2 2 3 4 5 5 6 6 6 7 7 7 7 7 8 8 8 0 1 2 2 3 3 5 5 9 0 3 Key: 7 | 6 = 76 degrees Fahrenheit

  17. ~Box & Whisker Plots~

  18. Step 1 – Order Numbers 1. Order the set of numbers from least to greatest

  19. Step 2 – Find the Median 2. Find the median. The median is the middle number. If the data has two middle numbers, find the mean of the two numbers. What is the median?

  20. Step 3 – Upper & Lower Quartiles 3. Find the lower and upper quartiles. These are the middle numbers on each side of the median. What are they?

  21. Step 4 – Draw a Number Line Now you are ready to construct the actual box & whisker graph. First you will need to draw an ordinary number line that extends far enough in both directions to include all the numbers in your data:

  22. Step 5 – Draw the Parts Locate the main median12 using a vertical line just above your number line:

  23. Step 5 – Draw the Parts Locate the lower quartile (8.5) and the upper quartile (14) with similar vertical lines:

  24. Step 5 – Draw the Parts Next, draw a box using the lower and upper quartile lines as endpoints:

  25. Step 5 – Draw the Parts Finally, the whiskers extend out to the data's smallest number 5 and largest number 20:

  26. Step 6 - Label the Parts of a Box-and-Whisker Plot Lower Quartile Median Upper Quartile 3 1 2 Lower Extreme Upper Extreme 4 5

  27. You Try! • There are 31 days in August, and here are the temperatures for that month: August 69 70 71 71 72 72 72 73 74 75 75 76 76 76 77 77 77 77 77 78 78 80 81 82 82 83 83 85 85 90 93
