Math Problem Statement

list 5 number summary for this data set = [3,8,7,10,4,24,3,12,7,2,6,5,4,1,6,5,14,3,17,1,24,14,2,16,4,2,5,5,3,8,12,15]

Solution

The 5-number summary of a data set includes the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum. Here's how the 5-number summary is calculated for your data set:

Data set (sorted):

1,1,2,2,2,3,3,3,3,4,4,4,5,5,5,5,6,6,7,7,8,8,10,12,12,14,14,15,16,17,24,241, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 5, 5, 6, 6, 7, 7, 8, 8, 10, 12, 12, 14, 14, 15, 16, 17, 24, 24

Calculations:

  1. Minimum (Min): The smallest value = 1
  2. First Quartile (Q1): Median of the lower half (excluding the overall median)
    Lower half: 1,1,2,2,2,3,3,3,3,4,4,4,5,5,5,51, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 5, 5
    Median of lower half: (3+3)/2=3(3 + 3)/2 = 3Q1 = 3
  3. Median (Q2): Middle value of the sorted data set
    Middle values: 5,65, 6 → Median = (5+6)/2=5.5(5 + 6)/2 = 5.5Median = 5.5
  4. Third Quartile (Q3): Median of the upper half (excluding the overall median)
    Upper half: 6,7,7,8,8,10,12,12,14,14,15,16,17,24,246, 7, 7, 8, 8, 10, 12, 12, 14, 14, 15, 16, 17, 24, 24
    Median of upper half: (12+12)/2=12(12 + 12)/2 = 12Q3 = 12
  5. Maximum (Max): The largest value = 24

Final 5-number summary:

  • Minimum = 1
  • Q1 = 3
  • Median = 5.5
  • Q3 = 12
  • Maximum = 24

Here are 5 related questions for further understanding:

  1. How do you calculate quartiles for larger or odd-sized data sets?
  2. What does the interquartile range (IQR) tell us about this data set?
  3. How can outliers affect the 5-number summary?
  4. How is the 5-number summary used in boxplots?
  5. Can you explain the difference between population and sample data for summaries?

Tip: When dealing with grouped data or larger data sets, always verify your sorted list for errors before calculating quartiles!
