Solution
To find the median of a data set, follow these steps:
Step 1: Arrange the data in ascending order.
The given data is:
Arranging in ascending order:
Step 2: Determine the number of data points.
There are 8 data items in total.
Step 3: Identify the middle position(s).
- Since the number of data points () is even, the median is the average of the two middle values.
- The two middle values are the 4th and 5th items in the sorted list:
Step 4: Calculate the median.
Final Answer:
The median is 23.5.
Would you like a detailed explanation of the process or examples of similar problems? Here are five related questions to deepen your understanding:
- How do you find the median if the data set contains an odd number of items?
- What is the difference between mean and median in a data set?
- How does adding an additional data point affect the median?
- Can the median be a value not present in the original data set? Why?
- How does the presence of outliers affect the median compared to the mean?
Tip: The median is less sensitive to outliers than the mean, making it a better measure of central tendency for skewed data!
