Math Problem Statement

Here is a set of sample data 1 5 6 9 10 33 36 37 43 45 46 48 49 52 59 63 80 81 85 89 92 94 96

Identify the 5 number summary (min, Q1, median, Q3, max) , , , ,

Solution

To find the 5-number summary (Minimum, Q1, Median, Q3, Maximum), we need to arrange all the numbers in order and then calculate the key values.

Here is the dataset in order:

1, 5, 6, 9, 10, 33, 36, 37, 43, 45, 46, 48, 49, 52, 59, 63, 80, 81, 85, 89, 92, 94, 96

Steps:

  1. Minimum (Min): The smallest number in the data set.
  2. First Quartile (Q1): The median of the lower half of the data (excluding the overall median if the number of data points is odd).
  3. Median: The middle value of the dataset.
  4. Third Quartile (Q3): The median of the upper half of the data (excluding the overall median if the number of data points is odd).
  5. Maximum (Max): The largest number in the dataset.

Calculations:

  • Min: 1 (smallest value)
  • Q1: The lower half is {1, 5, 6, 9, 10, 33, 36, 37, 43, 45, 46}, and its median (Q1) is 36.
  • Median: The full dataset has 24 values, so the median is the average of the 12th and 13th values: (48 + 49) / 2 = 48.5.
  • Q3: The upper half is {48, 49, 52, 59, 63, 80, 81, 85, 89, 92, 94, 96}, and its median (Q3) is 81.
  • Max: 96 (largest value)

Final 5-number summary:

Min = 1, Q1 = 36, Median = 48.5, Q3 = 81, Max = 96
