Q: The median of the following data set: 3, 7, 9, 15, 20 is?
Solution:
Arranging the data: 3, 7, 9, 15, 20. Median = 9 (middle value).
Steps: 6
Show Steps
Step 1: Write down the data set: 3, 7, 9, 15, 20.
Step 2: Arrange the data in order from smallest to largest (if not already done). The data is already in order: 3, 7, 9, 15, 20.
Step 3: Count how many numbers are in the data set. There are 5 numbers.
Step 4: Find the middle number. Since there are 5 numbers (an odd amount), the middle number is the 3rd number in the list.
Step 5: Identify the 3rd number in the ordered list, which is 9.
Step 6: Conclude that the median of the data set is 9.
