- 1. Explore how toorganize and present data INSPIRED BY
- 2. • Mean • Median •Frequency • Mode Presenting Results Summarizing Results
- 3. How can Janorganize and present the results? Jan asks 15 of her friends what their favorite color is. Here are the answers she gathered:
- 4. Summarize data using frequency,mode, mean, and median. Present data using a frequency table. Create a conclusion from the data.
- 5. Presenting Results refers tothe number of times a result appears in the data set refers to the result with the greatest frequency
- 6. Presenting Results It isused to represent the frequency of different results in the data. result or data value frequency
- 7. Presenting Results Pink 6 Green2 Blue 3 Yellow 4 Which color is the mode? The equivalent frequency of Jan's poll is shown below:
- 8. Pink 6 Green 2 Blue3 Yellow 4 Presenting Results The equivalent frequency of Jan's poll is shown below: Remember: A data set may have one mode, multiple modes, or no mode.
- 9. 14, 2, 5,2, 2, 5, 5, 7, 12, 13, 13, 14 A grade 6 class has the following sets of scores in a quiz. Create a frequency table for the data set. 1. What is/are the mode/s of the data set? 2.How many students are there in the class?
- 10. 2 3 5 3 71 12 1 13 2 14 2 Answer Key 1. The modes of the data set are 2 and 5. 2. There are 12 students in the class.
- 11. Summarizing Results Two measuresof center can be used to summarize numerical data sets: the mean and the median. average of all the data values in the set the "middlemost" value in the set Mean = sum of all data values number of data values
- 12. The mean oraverage of the data set is 6. Find the mean of the following data set: 8, 3, 4, 9, 6 Summarizing Results Mean = sum of all data values number of data values Mean = Mean = = 6
- 13. Summarizing Results Finding themedian changes depending on the number of values in the data set. Arrange the values from least to greatest. least greatest Median If odd number of values: If even number of values: Median: + 2
- 14. Find the medianof the following data sets: Summarizing Results Set A: 8, 3, 4, 9, 6 3, 4, 6, 8, 9 Median Set B: 11, 17, 3, 14, 19, 7 3, 7, 11, 14, 17, 19 Median = = 12.5
- 15. A B C D Which two datasets have the same mean? 9, 11, 15, 21, 7 12, 11, 14, 15, 9 7, 11, 30, 8, 9 6, 14, 10, 13, 22 Find also the median for all four data sets.
- 16. Answer Key Which twodata sets have the same mean? 9, 11, 15, 21, 7 12, 11, 14, 15, 9 7, 11, 30, 8, 9 6, 14, 10, 13, 22 C and D have the same mean of 13. Mean: 13 Mean: 13 Mean: 12.6 7, 9, 11, 15, 21 Median: 11 Mean: 12.2 9, 11, 12, 14, 15 Median: 12 7, 8, 9, 11, 30 Median: 9 6, 10, 13, 14, 22 Median: 13 A B C D
- 17. average of all thedata values in the set result with the greatest frequency number of times a result appears in the data set the "middlemost" value
- 18. Design a surveyfor classmates. Choose one question from the provided options or create your own. • What are your preferred sports? • How many pets do you have at home? • What is your mode of transportation when traveling to school? Organize, summarize, and present the data you collected in a poster.
