The model relating accuracy to individual difference variables was
estimated for each of the four accuracy measures (see Table V). The best fit is
obtained using the most sophisticated accuracy measure, AccD. Although the
model overall is significant at the 10 per cent level, the adjusted R2 is only 9 per
cent. In general, the coefficient estimates have the expected sign (the exception
being the format preference dummy variable for the AccD variant). The
constant term is highly significant in each model, indicating the baseline
accuracy level to be expected. Only the FINUND variable is significant (at
either the 0.01 or 0.05 level) across all variants. None of the other three variables
is significant using any variant. Thus, it appears that higher levels of declared
financial understanding are associated with greater accuracy in perceiving
differences in corporate performance that are portrayed graphically.
