frequencies for A and B, B and C and A and C. The distances deduced from
the straight line should be additive, i.e.
then,
D
AB
+ D
BC
= D
AC
.
Consider an actual experiment with the following results (Singer
et al
.,
1965):
c.f.
AB
= 0.42 ,
c.f.
BC
= 0.57 ,
and
c.f.
Ac
= 0.19 .
Then, based on the straight line, we get.
D
AB
=
1.16 min ,
D
BC
= 0.86 min ,
and
D
AC
= 1.62 min .
However,
D
AB
+ D
BC
= 2.02 min 1.62 min = D
AC
.
