Step-by-step Solution
To find the median and mode of the data set \( 5, 10, 5, 15, 5, 20 \), we will follow these steps:
### Step 1: Find the Mode
The mode is the number that appears most frequently in a data set.
In the given data:
- \( 5 \) appears \( 3 \) times
- \( 10 \) appears \( 1 \) time
- \( 15 \) appears \( 1 \) time
- \( 20 \) appears \( 1 \) time
Since \( 5 \) appears the most frequently, the mode is:
\[
\text{Mode} = 5
\]
### Step 2: Find the Median
To find the median, we first need to arrange the data in ascending order:
\[
5, 5, 5, 10, 15, 20
\]
Since there are \( 6 \) numbers in the data set (an even number), the median will be the average of the two middle numbers. The two middle numbers in this ordered list are the \( 3^{rd} \) and \( 4^{th} \) numbers:
- \( 3^{rd} \) number: \( 5 \)
- \( 4^{th} \) number: \( 10 \)
Now, we calculate the median:
\[
\text{Median} = \frac{5 + 10}{2} = \frac{15}{2} = 7.5
\]
### Summary
- **Mode**: \( 5 \)
- **Median**: \( 7.5 \)
Quick Answer
Mode: 5, Median: 7.5
