  1. Displaying and Analyzing Data Chapter 11-1 Notes: Reporting Frequency

  2. Who Remembers Mean, Median, Mode? • The MEAN of a set of data is the sum of the data divided by the number of items (the average) • Example: 79 + 42 + 62 + 18 + 54 = 255 = 51 5 5 • The MEDIAN of a data set is the middle value when the data are arranged in numerical order. • Example: 1 2 2 4 6 6 6 7 8 • The MODE of a data set is the item that occurs most frequently. • Example: 17 16 18 17 16 17 = 17

  3. How Can We Report Frequency? • A Frequency Table is a table that lists each item in a data set with the number of times the item occurs. • Let’s look at this example: • Ice Creams sold each day at lunch: 45 48 53 50 46 46 50 51 48 46 45 50 49 46, 51

  4. Try this on your own! • The Numbers below represent the ages of the students in a gymnastics class. • Make a Frequency Table of the data. • 11 5 9 13 8 9 9 11 10 8 6 7 12 11 13 12 7 6 11 12 10 8

  5. Let’s fill it in! Check Your Answers.

  6. Here’s Another way to Display Data: • A LINE PLOT is a graph that shows the shape of a data set by stacking X’s above each data value on a number line. X X X X X X X X X X X X __________________________________________________ 1 2 3 4 5 6 7 8

  7. Let’s Try This One: • For Example: Ty is planning a school garden. He asked his teachers how many rose bushes they would like in the garden. He recorded the data in a frequency table. • Use the Frequency Table to make a Line Plot.
