Step 1
"Mode" = 7 \text{ because it appears three times}
To find the mode, we need to identify the number that appears most frequently in the list.
Step 2
Median = \frac{5^{th} \text{ number} + 6^{th} \text{ number}}{2} = \frac{5 + 7}{2} = 6
Before calculating the median, let's first arrange the numbers in ascending order: Since there are 10 numbers (even), the median is the average of the two middle numbers. The two middle numbers are the 5th and 6th numbers:
Final Answer
- Mode: 7 - Median: 6 - Mean: 5.2 - Range: 7
