Median

  • Median is the midpoint of the data set when the data is arranged in ascending or
  • descending order
  • Half of the observations lie above the median and half are below
  • Median is important because arithmetic mean can be affected by extremely large or small values

Example

Find the median of the following data set:
3, 13, 7, 5, 21, 23, 39, 23, 40, 23, 14, 12, 56, 23, 29
 

Solution

Arrange the values in ascending order
3, 5, 7, 12, 13, 14, 21, 23, 23, 23, 23, 29, 39, 40, 56
Total number of observations = 15
Median = Middle observation = 8th observation
Median = 23
