What is the median of a data set?
The median is the middle value of a data which is arranged in either ascending/descending order.
What are quartiles?
The values that divide your data into quarters are called quartiles. The four quarters are:
- The lowest 25% of numbers.
- The next lowest 25% of numbers (up to the median)
- The second highest 25% of numbers (above the median)
- The highest 25% of numbers
Steps
- Arrange the data in ascending/descending order:
4, 5, 7, 11, 12, 15, 16, 18
- The total number of entries = 8
- No. of Quartiles = Total entries/ 4 = 8 / 4 = 2
Hence the quartiles will be (4 , 5 ), (7 , 11), (12,15), (16,18).
