  2. Student Learning Goal Chart Lesson Reflection for Chapter 4 Section 7

  3. Pre-Algebra Learning Goal Students will understand collecting, displaying, & analyzing data.

  4. Students will understand collecting, displaying & analyzing data by being able to do the following: • Learn to identify populations & recognize biased samples (4-1) • Learn to organize data in tables and stem-and-leaf plots (4-2) • Learn to find Euler circuits (14-6) • Learn to find and use Hamiltonian circuits (14-7) • Learn to find appropriate measures of central tendency (4-3) • Learn to find measures of variability (4-4) • Learn to display data in bar graphs, histograms, and line graphs (4-5) • Learn to recognize misleading graphs and statistics (4-6) • Learn to create and interpret scatter plots (4-7)

  5. Today’s Learning Goal Assignment Learn to create and interpret scatter plots.

  8. 4-7 Scatter Plots C D A B Pre-Algebra Warm Up Graph each point on the same coordinate plane. 1.A (5, 20) 2.B (20, 15) 3. C (10, 40) 4. D (30, 35)

  9. Problem of the Day What is the least number that can be divided evenly by each of the numbers 1 through 12? 27,720

  10. Today’s Learning Goal Assignment Learn to create and interpret scatter plots.

  11. Vocabulary scatter plot correlation line of best fit

  12. A scatter plot shows relationships between two sets of data.

  13. Additional Example 1: Making a Scatter Plot of a Data Set Use the given data to make a scatter plot of the weight and height of each member of a basketball team. The points on the scatter plot are (71, 170), (68, 160), (70, 175), (73, 180), and (74, 190).

  14. Try This: Example 1 Use the given data to make a scatter plot of the weight and height of each member of a soccer team. 200 190 180 170 160 150 140 130 120 Height (in) Weight (lbs) 63 125 67 156 69 175 Weight 68 135 62 120 The points on the scatter plot are (63, 125), (67, 156), (69, 175), (68, 135), and (62, 120). 60 61 62 63 64 65 66 67 68 69 Height

  15. Correlation describes the type of relationship between two data sets. The line of best fitis the line that comes closest to all the points on a scatter plot. One way to estimate the line of best fit is to lay a ruler’s edge over the graph and adjust it until it looks closest to all the points.

  16. No correlation; as one data set increases, the other decreases. Negative correlation; as one data set increases, the other decreases. Positive correlation; both data sets increase together.

  17. Additional Example 2A: Identifying the Correlation of Data Do the data sets have a positive, a negative, or no correlation?. A. The size of a jar of baby food and the number of jars of baby food a baby will eat. Negative correlation: The more food in each jar, the fewer number of jars of baby food a baby will eat.

  18. Try This: Example 2A Do the data sets have a positive, a negative, or no correlation?. A. The size of a car or truck and the number of miles per gallon of gasoline it can travel. Negative correlation: The larger the car or truck, the fewer miles per gallon of gasoline it can travel.

  19. Additional Example 2B: Identifying the Correlation of Data Do the data sets have a positive, a negative, or no correlation?. B. The speed of a runner and the number of races she wins. Positive correlation: The faster the runner, the more races she will win.

  20. Try This: Example 2B Do the data sets have a positive, a negative, or no correlation?. B. Your grade point average and the number of A’s you receive. Positive correlation: The more A’s you receive, the higher your grade point average.

  21. Additional Example 2C: Identifying the Correlation of Data Do the data sets have a positive, a negative, or no correlation?. C. The size of a person and the number of fingers he has No correlation: A person generally has ten fingers regardless of their size.

  22. Try This: Example 2C Do the data sets have a positive, a negative, or no correlation?. C. The number of telephones using the same phone number and the number of calls you receive. No correlation: No matter how many telephones you have using the same telephone number, the number of telephone calls received will be the same.

  23. Additional Example 3: Using a Scatter plot to Make Predictions Use the data to predict how much a worker will earn in tips in 10 hours. According to the graph, a worker will earn approximately $24 in tips in 10 hours.

  24. Try This: Example 3 Use the data to predict how many circuit boards a worker will assemble in 10 hours. 141210 8 6 4 2 Hours According to the graph, a worker will assemble approximately 10 circuit boards in 10 hours. 2 4 6 8 10 12 14 Circuit Board Assemblies

  25. Lesson Quiz: Part 1 1. Use the given information to make a scatter plot.

  26. Lesson Quiz: Part 2 Do the data sets have a positive, negative, or no correlation? 2. the minimum wage and the year 3. the amount of precipitation and the day of the week 4. the amount of germs on your hands and the number of times you wash your hands in a day positive no correlation negative
