💡 Analysis & Explanation
Statistical Methodology ▼
To accurately find the median, the given raw dataset must first be systematically and strictly arranged in either ascending or descending order.
Data Ordering ▼
Arranging the provided scrambled numbers (55, 53, 56, 59, 61, 69, 31) from the absolute smallest to the largest yields the linear sequence: 31, 53, 55, 56, 59, 61, 69.
Identifying the Center ▼
Since there are exactly 7 discrete individual data points (an odd number), the median is the single value located directly in the exact middle, which is the 4th position.
Conclusion ▼
The geometric middle value, and thus the true median, is definitively 56.
