What is the median of the numbers?

1 answer

To find the median of the number of laps run by the clients, we first need to list the numbers in ascending order:

0, 1, 2, 3, 4, 5, 6

Since there are 7 values (an odd number), the median is the middle value. To find the middle value:

  1. Count the total numbers: 7
  2. The median position is calculated as \((n + 1) / 2\), where \(n\) is the total number of values. \[ (7 + 1) / 2 = 8 / 2 = 4 \]
  3. The 4th number in the ordered list is the median.

Looking at the ordered list:

  • 1st number: 0
  • 2nd number: 1
  • 3rd number: 2
  • 4th number: 3 (this is the median)
  • 5th number: 4
  • 6th number: 5
  • 7th number: 6

Thus, the median of the numbers is 3.
