What does a residual value of 4. 5 mean in reference to the line of best fit? The data point is 4. 5 units above the line of bes
Kamila [148]

A line of best fit is a line drawn at average distance to a series of scattered points. Thus, the correct option is:

Option B. The <em>data</em> point is 4. 5 units <u>below</u> the line of best fit.

A graph is said to be formed by plotted points on a <u>Cartesian </u>coordinate plane. When the plotted <em>points</em> are <u>scattered</u>, a <em>line of best fit</em> is required to shoe the relationship among the plotted <em>points</em>.

A <u>residual</u> <u>value</u> is a form of error that is determined from the <em>line of best fit</em>. A <u>line of best fit</u> is a line drawn at <em>average</em> point to a <em>series</em> of plotted <em>scattered</em> points.

Therefore, a residual value of 4.5 with respect to a <em>line of best fit</em> implies that: The data point is 4. 5 units <u>below</u> the <em>line of best fit</em>.

Thus the <em>correct</em> option is B.
