Question

The least-squares regression line is_____________. A. the line that passes through the most data points.B. the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as small as possible.C. the line such that half of the data points fall above the line and half fall below the line.D. All of the above

Answer 1

Answer:

The option B) is correct.

That is the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as small as possible is correct answer

Step-by-step explanation:

Given that " The least-squares regression line "

The least-squares regression line is the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as small as possible.

Therefore option B) is correct

Answer 2

Answer:

a. The line is located on a scatterplot so that it minimizes the squared distances from the points to the line.
