  3. I will make and interpret line plots. • line plot • range • outlier Main Idea/Vocabulary

  4. Make a Line Plot Callie surveyed sixteen students to find the number of pets each owned. The results of her survey were: 1, 5, 0, 2, 2, 0, 3, 4, 2, 1, 0, 1, 1, 0, 3, 1. Make a line plot of the data. Then describe the data presented in the graph. Step 1 Draw and label a number line. Example 1

  5. Make a Line Plot Step 2 Place as many Xs above each number as there are responses for that number. Example 1

  6. Make a Line Plot Step 3 Describe the data. • 16 students responded to the question. • No one owns more than 5 pets. • Four students do not own any pets. • The response given most is 1 pet owned. This represents the mode. Answer: So, 16 students were surveyed. More people owned 1 pet than any other number. Example 1

  7. A B C D Which statement best describes the data shown? • The most number of siblings students have are 4. • 14 students were surveyed. Most people have 2 siblings. • 14 students were surveyed. More people had 3 siblings than 0 siblings. • No students have siblings. Example 1

  9. Analyze Line Plots The line plot shows the prices of sneakers in one store. Find the median and the mode of the data. Then describe the data using them. Example 2

  10. Analyze Line Plots There are 22 numbers represented in the line plot. The two middle numbers, shown on the line plot, are $45 and $45. So, the median is $45. This means that half of the sneakers cost more than $45 and half cost less than $45. The number that appears most often is $40. So, the mode of the data is $40. This means that more sneakers cost $40 than any other price. Example 2

  11. Analyze Line Plots Answer: So, the median is $45 and the mode is $40. Half of the sneakers cost less than or equal to $45 and more sneakers cost $40 than any other price. Example 2

  12. A B C D What is the median and mode of the data? • median 45; mode 45 • median 40; mode 45 • median 35; mode 40 • median 60; mode 70 Example 2

  13. Analyze Line Plots Find the range and any outliers of the data. Then describe the data using them. Example 3

  14. Analyze Line Plots range = greatest value – least value = $70 – $35, or $35 Answer: So, the range of the prices is $35. The price $70 is much higher than the rest of the prices. So, $70 is an outlier. Example 3

  15. A B C D What is the range and any outliers of the data? • range 35; outlier 35 • range 35; no outliers • range 35; outlier 45 • range 35; outlier 70 Example 3
