Figure 7
The graph plots relative frequency on the vertical axis and percentage error on the horizontal axis. Vertical bars represent percentage error relative frequency, with higher frequencies at low percentage error values and decreasing frequencies as percentage error increases. A smooth curve represents a power law distribution fitted over the bars. The curve follows a decreasing trend from left to right, aligning closely with the tops of the bars. A legend identifies percentage error relative frequency and the power law distribution curve.Histogram showing the relative frequency of percentage errors represented by the power-law distribution
