Difficulty: EasyMeasures of Central Tendency

A mechanic serviced the following number of vehicles over a five-day period: 1010, 1515, 44, 1111, and 55.

What is the median number of vehicles serviced during this period?

  1. A
    44
  2. B
    99
  3. 1010Answer
  4. D
    1111

Answer

The median number of vehicles serviced is 1010.
To find the median, the values must first be ordered from least to greatest: 44, 55, 1010, 1111, 1515. The median is the middle number in this ordered list, which is 1010.

Step-by-Step Solution

1
Arrange the numbers in ascending order.
44, 55, 1010, 1111, 1515
The median requires the data set to be sorted from least to greatest.
2
Identify the middle value in the sorted list.
The middle value is 1010.
Since there is an odd number of values in the list (five days), the median is exactly the middle number.
