  1. Quartiles & Extremes (displayed in a Box-and-Whisker Plot) Lower Extreme Lower Quartile Median Upper Quartile Upper Extreme Back

  2. Interquartile Range (IQR)

  3. Lower Extreme Definition: Lowest number in the data set Location on a box-and-whisker plot: End of left whisker Example: 250, 325, 340, 390, 440, 520, 730

  4. Lower Quartile Definition: Median of the lower half of the data Location on a box-and-whisker plot: Left end of the box Example: 250, 325, 340, 390, 440, 520, 730

  5. Median Definition: Middle number when data is in order from least to greatest. Location on a box-and-whisker plot: Line inside of the box Example: 250, 325, 340, 390, 440, 520, 730

  6. Upper Quartile Definition: Median of the upper half of the data Location on a box-and-whisker plot: Right end of the box Example: 250, 325, 340, 390, 440, 520, 730

  7. Upper Extreme Definition: Highest number in the data set Location on a box-and-whisker plot: End of right whisker Example: 250, 325, 340, 390, 440, 520, 730

  8. Interquartile Range (IQR) Definition: Difference between the upper & lower quartiles Location on a box-and-whisker plot: Length of the box Example: 250, 325, 340, 390, 440, 520, 730 195 520-325 = 195
