Figure 35. Box plot of acceptability of photo series – Blair Valley
The acceptability measures discussed previously are reinforced by the mean and
median scores given each photo. Table 44 illustrates where the median score (mostoften
assigned) is within the acceptable range (green) and where it falls below the range
of acceptability (red). Table 45 demonstrates the break-point where the majority of
people responding found conditions unacceptable.
