  4. 5-Number (5#) Summary The five-number summary of a distribution consists of the smallest data point, the first quartile, the median, the third quartile, and the largest data point.

  5. Number of Text Messages First we must put the data in order from smallest to largest. ***Sample Size:

  6. #3 Median The median is the midpoint of the distribution that has been ordered from smallest to largest, such that half of the data points are smaller and half of the data points are larger. Notation: _________

  7. #1 Minimum The minimum is the smallest data point in the data set. Do not exclude any outliers. Notation: ____________

  8. #5 Maximum The maximum is the largest data point in the data set. Do not exclude any outliers. Notation: ____________

  9. #2 Lower Quartile The median for the first 50% of the ordered set is the lower/first quartile. Notation: ___________

  10. What does Q1 Mean? _____________of the people in this room sent less than ___________ text messages. _____________ of the people in this room sent more than __________ text messages.

  11. #4 Upper Quartile The median for the second 50% of the ordered set is the upper/third quartile. Notation: ___________

  12. What does Q3 Mean? _____________of the people in this room sent less than ___________ text messages. _____________ of the people in this room sent more than __________ text messages.

  13. Data Display This is what the quartiles are actually doing with the data set.

  14. Interquartile Range The interquartile range is the range of data between the lower quartile and the upper quartile Notation: __________

  15. Number of Text Messages First we must put the data in order from smallest to largest. ***Sample Size:

  16. #3 Median The way we deal with the median in a data set with an ODD sample size is different. Once we find the median, it cannot be included in another portion (Q1 or Q3).

  17. Number of Tattoos Find the 5# Summary for the following data set. n = _____ 5 1 11 6 0 3 2 0 13 4 4 1 12 7 0 1

  18. Number of Starbucks Coffees Find the 5# Summary for the following data set. n = _____ 05 01 23 14 10 03 00 20 03 24 04 01 12 17

  19. Try It On Your Own One group has an ODD sample size and one group has an EVEN sample size.

  20. Ticket Out The Door On a 3x5 Card write what 5 values the 5# Summary is made up of.
