Understanding the Videographs
requires careful, repeated viewing because they track responses on a
number of different levels. It is important to consider not only the
horizontally moving blue and red lines which represent the running
average, but also the “histograms” - the vertical bars, at the bottom
of the screen.
The histograms show the percentage
of listeners responding to a sample at each of the levels of the 1 to 9
scale. Responses at the lower end of the scale (1, 2, 3 and 4) indicate
the proportion of listeners likely to tune-out when that sound is
played - even when there may be some listeners responding positively.
This provides perspective on whether the average represented by the
line graph is the result of consistent reactions that is mostly
positive or negative or mixed reactions on the scale (i.e. some
positive scores and some negative scores averaging out to low appeal).
