Warm - up

  • Find the mean of the following number sets.

  • 1. 2, 32, 6, 15, 12, 14

  • 2. 6, 45, 78, 21, 17, 16

  • 3. 7, 3, 1, 8, 4


Mean Absolute Deviation and Quartiles

6.7 and 6.8


Vocabulary

  • Measure of dispersion

    • A description of the dispersion or the spread of the data

  • Range

    • The difference between the greatest value and least value

  • Deviation from the mean

    • Is the difference of a data value and the mean of the data set


  • Mean absolute deviation

    • Is the average deviation of the data from the mean.


Find the mean absolute deviation

  • A) 9, 15, 28, 10, 8

  • B) 32, 33, 22, 85, 58


More mean absolute deviation

C. 24, 35, 18, 20, 17, 30

D) 116, 130, 120, 125, 140, 125


Now You Try

  • Find the mean absolute deviation

  • A) 105, 98, 95, 100, 95, 107

  • B) 36, 39, 58, 42, 106, 39, 48, 45


Vocabulary

  • Quartile

    • the median of an ordered data set

  • Upper Quartile

    • the median of the upper half of an ordered set

  • Lower Quartile

    • the median of the lower half of an ordered set

  • Interquartile range

    • The difference of the upper quartile and lower quartile


Examples

  • Find the mean, median, range, and the interquartile range.

  • Data set 1: 102, 105, 108, 110, 112, 113

  • Data set 2: 100, 103, 105, 106, 109, 113


Find the mean, median, range, and the interquartile range.

  • A) 4, 7, 14, 8, 9

  • B) 85, 90, 76, 65, 92, 88


Now You Try

  • Find the mean, median, range, and the interquartile range.

  • A) 110, 145, 115, 124, 118, 129, 119

  • B) 50, 55, 60, 58, 62, 57, 68, 51, 63
