Range between the quartiles. Q3 – Q1 Approximate the answers by referring to the box-and-whisker plot shown. 1. Find the 5-dot summary. Lower Extreme: Lower Quartile: Median: Upper Quartile: Upper Extreme: 2. What is the range of the data? 3. How much of the data is located between 110 and 140? 4. How much of the data is located between 70 and 110? 5. What is the interquartile range? 6. Compare the amount of data between 50 and 70 to the amount of data between 110 and 140. Box-And-Whisker Plots 50 60 70 80 90 100 110 120 130 140 IQR (Interquartile Range): Range between the quartiles. Q3 – Q1

7. What is the interquartile range? A. 5 C. 20 B. 15 D. 35 8. What percent of student scores fall between 65 and 95? A. 25% C. 50% B. 30% D. 75% 9. 10. 11. Follow the instructions below to create a box-and-whisker plot from the given data. Order your data and make a 5-dot summary. Create a number line (how to space your tick marks, what to count by, etc.) Plot the 5 dots. Extend whiskers from the extremes inward; create a box between the quartiles; draw a line for the median. Label the numbers and vocabulary on your plot. 11, 19, 5, 34, 9, 25, 28, 16, 17, 11, 12, 7 Lower Extreme: Lower Quartile: Median: Upper Quartile: Upper Extreme:
