  9. Monday, March 17 Chapter 11.1/11.2 Mean, Median and Mode

  10. Mean, Median and Mode Objective: To find and interpret the mean, median and mode from a data set.

  11. Mean, Median and Mode At the end of this lesson you should be able to answer the following question. How are mean and median similar?

  12. Mean, Median and Mode The mean, median and mode are called measures of center because they describe the center of the data set.

  13. Mean, Median and Mode The mean (or average) of a data set is the sum of the data divided by the number of pieces of data. It is the balance point of the data set.

  14. Mean, Median and Mode The mean (or average) of a data set is the sum of the data divided by the number of pieces of data. The median of a data set is the value at the center of an ordered set, or the mean of the two central values.

  15. Mean, Median and Mode The mean (or average) of a data set is the sum of the data divided by the number of pieces of data. The median of a data set is the value at the center of an ordered set, or the mean of the two central values. The mode is the number or numbers that appears most often in a data set.

  16. Mean, Median and Mode Dave recorded his 7 tests scores on the table. Find the mean, median and mode. Round to the tenth, if needed. To Find the Mean. Step 1 – Add the numbers in the data set.

  17. Mean, Median and Mode Dave recorded his 7 tests scores on the table. Find the mean, median and mode. Round to the tenth, if needed. 93+85+88+97+94+90+93=640 To Find the Mean. Step 1 – Add the numbers in the data set.

  18. Mean, Median and Mode Dave recorded his 7 tests scores on the table. Find the mean, median and mode. Round to the tenth, if needed. 93+85+88+97+94+90+93=640 To Find the Mean. Step 2 – Divide the sum by how many numbers are in the data set.

  19. Mean, Median and Mode Dave recorded his 7 tests scores on the table. Find the mean, median and mode. Round to the tenth, if needed. 93+85+88+97+94+90+93=640 640 ÷ 7= 91.4 To Find the Mean. Step 2 – Divide the sum by how many numbers are in the data set.

  20. Mean, Median and Mode Dave recorded his 7 tests scores on the table. Find the mean, median and mode. Round to the tenth, if needed. 93+85+88+97+94+90+93=640 640 ÷ 7= 91.4 Caution: If you are using a calculator , use parenthesis around the added numbers prior to dividing.

  21. Mean, Median and Mode Dave recorded his 7 tests scores on the table. Find the mean, median and mode. Round to the tenth, if needed. To Find the Median. Step 1 – Order the data set from least to greatest.

  22. Mean, Median and Mode Dave recorded his 7 tests scores on the table. Find the mean, median and mode. Round to the tenth, if needed. 85, 88, 90, 93, 93, 94, 97 To Find the Median. Step 1 – Order the data set from least to greatest.

  23. Mean, Median and Mode Dave recorded his 7 tests scores on the table. Find the mean, median and mode. Round to the tenth, if needed. 85, 88, 90, 93, 93, 94, 97 To Find the Median. Step 2– Find the middle number or the mean of the two middle numbers.

  24. Mean, Median and Mode Dave recorded his 7 tests scores on the table. Find the mean, median and mode. Round to the tenth, if needed. 85, 88, 90, 93, 93, 94, 97 To Find the Median. Step 2 – Find the middle number or the mean of the two middle numbers.

  26. Mean, Median and Mode Dave recorded his 7 tests scores on the table. Find the mean, median and mode. Round to the tenth, if needed. Mean – 91.4 Median – 93 Mode - 93

  27. Mean, Median and Mode Find the mean, median and mode of the temperatures on the graph. Round to the tenth, if needed. Do this on your own.

  28. Mean, Median and Mode Find the mean, median and mode of the temperatures on the graph. Round to the tenth, if needed. Mean 64.4 + 71.2 + 55.8 + 58.2= 249.6 246.6 ÷ 4 = 62.4

  30. Mean, Median and Mode Find the mean, median and mode of the temperatures on the graph. Round to the tenth, if needed. Mode Since no numbers occur more than once, there is no mode.

  31. Mean, Median and Mode A stem and leaf plot organizes data from least to greatest. The “stem” is the first digit and the “leaf” is the second digit in each number. For example, in the number 32, the “3” would be the “stem” and the “2” would be the “leaf”.

  32. Mean, Median and Mode What is the mean, median and mode of the data in this stem and leaf plot? Do this on your own.

  33. Mean, Median and Mode What is the mean, median and mode of the data in this stem and leaf plot? Mean 78+85+88+89+92+96= 718 718 ÷ 6 = 75

  34. Mean, Median and Mode What is the mean, median and mode of the data in this stem and leaf plot? Mean 78+85+88+89+92+96= 718 528÷ 6 = 88

  35. Mean, Median and Mode What is the mean, median and mode of the data in this stem and leaf plot? Median 78,85,88,89,92,96 88 + 89 = 88.5

  36. Mean, Median and Mode What is the mean, median and mode of the data in this stem and leaf plot? Mode There is no mode.

  37. Mean, Median and Mode What is the mean, median and mode of the cost of juice? Do this on your own.

  38. Mean, Median and Mode What is the mean, median and mode of the cost of juice? Mean 1.65+1.97+2.45+2.87+2.35+3.75+2.49+2.97= 20.50 20.50 ÷ 8 = 2.56

  39. Mean, Median and Mode What is the mean, median and mode of the cost of juice? Mode 2.87

  40. Mean, Median and Mode Mike raked the leaves from 6 lawns. He earned $12, $10, $13, $15, and $15 for five lawns. How much did he earn the sixth time if the mean of the data is $12? Do this on your own.

  41. Mean, Median and Mode Mike raked the leaves from 6 lawns. He earned $12, $10, $13, $15, and $15 for five lawns. How much did he earn the sixth time if the mean of the data is $12? 12 + 10 + 13 + 15 + 15 + x = 12 · 6 65 + x = 72 -65 -65 x = 7

  42. Mean, Median and Mode How are mean and median similar?
