Solution
Solution Steps
Step 1: Understanding the Question
The question asks to fill in the blank regarding a property of a straight line in the context of minimizing the sum of the squares of the residuals. The options provided include terms related to statistical analysis.
Step 2: Identifying the Correct Term
The term that describes the property of a straight line that minimizes the sum of the squares of the residuals is known as the "least-squares property." This method is commonly used in linear regression to find the best-fitting line.
Step 3: Filling in the Blank
By substituting the correct term into the question, we arrive at the complete statement:
"A straight line satisfies the least-squares property if the sum of the squares of the residuals is the smallest sum possible."
Final Answer
The answer is \(\boxed{\text{least-squares property}}\).
