Question

4 which scatter plot does not show an appropriate line of best fit?
a
b
c
d

Explanation:

A line of best fit should closely follow the overall trend of the data points, with points distributed relatively evenly around it.

• Option A: Points follow a downward trend, line matches.
• Option B: Points follow an upward trend, line matches.
• Option C: The line is too steep and does not align with the general downward trend of the majority of points; most points lie far below the line, so this is not an appropriate line of best fit.
• Option D: Points follow an upward trend, line matches.
