Abstract
The Tucker and Levine equally reliable linear methods
for test form equating in the common-item nonequivalent-
populations design are formulated in a way
that promotes understanding of the methods. The formulation
emphasizes population notions and is used to
draw attention to the practical differences between the
methods. It is shown that the Levine method weights
group differences more heavily than the Tucker
method. A scheme for forming a synthetic population
is suggested that is intended to facilitate interpretation
of equating results. A procedure for displaying form
and group differences is developed that also aids interpretation.
