Base on the data above, identify the 5 number summary 

Solution

To identify the 5-number summary for the given data set, we'll follow these steps:

Step 1: List all the values in ascending order

The given data is:

32,6,26,60,80,36,29,100,74,21,99,67,24,43,66,58,89,90,38,10,59,75,69,8632, 6, 26, 60, 80, 36, 29, 100, 74, 21, 99, 67, 24, 43, 66, 58, 89, 90, 38, 10, 59, 75, 69, 86

Arranging these values in ascending order:

6,10,21,24,26,29,32,36,38,43,58,59,60,66,67,69,74,75,80,86,89,90,99,1006, 10, 21, 24, 26, 29, 32, 36, 38, 43, 58, 59, 60, 66, 67, 69, 74, 75, 80, 86, 89, 90, 99, 100

Step 2: Calculate the 5-number summary

  1. Minimum: The smallest value in the data set.

    • Min=6\text{Min} = 6
  2. Maximum: The largest value in the data set.

    • Max=100\text{Max} = 100
  3. Median (Q2): The middle value of the data set.

    • Since there are 24 values, the median will be the average of the 12th and 13th values:
    • Median Q2=59+602=59.5Q2 = \frac{59 + 60}{2} = 59.5
  4. First Quartile (Q1): The median of the lower half of the data.

    • The lower half includes the first 12 values: 6,10,21,24,26,29,32,36,38,43,58,596, 10, 21, 24, 26, 29, 32, 36, 38, 43, 58, 59
    • Q1=29+322=30.5Q1 = \frac{29 + 32}{2} = 30.5
  5. Third Quartile (Q3): The median of the upper half of the data.

    • The upper half includes the last 12 values: 60,66,67,69,74,75,80,86,89,90,99,10060, 66, 67, 69, 74, 75, 80, 86, 89, 90, 99, 100
    • Q3=75+802=77.5Q3 = \frac{75 + 80}{2} = 77.5

Final 5-number summary:

  • Minimum: 6
  • First Quartile (Q1): 30.5
  • Median (Q2): 59.5
  • Third Quartile (Q3): 77.5
  • Maximum: 100

Would you like more details or have any other questions?


Here are 5 related questions for further exploration:

  1. How does the mean compare to the median in this data set?
  2. What does the interquartile range (IQR) tell you about the spread of the middle 50% of data?
  3. How would the 5-number summary change if an outlier was added to this data set?
  4. Can you identify any potential outliers in this data set?
  5. How does the 5-number summary help in constructing a box plot?

Tip: Always ensure that data is sorted correctly before calculating the quartiles for an accurate 5-number summary.
