Abstract
The delta method was used to derive standard
errors (SEs) of the Levine observed score and
Levine true score linear equating methods. SEs with
a normality assumption as well as without a normality
assumption were derived. Data from two
forms of a test were used as an example to evaluate
the derived SEs of equating. Bootstrap SEs also
were computed for the purpose of comparison.
The SEs derived without the normality assumption
and the bootstrap SEs were very close. For the
skewed score distributions, the SEs derived with the
normality assumption differed from the SEs derived
without the normality assumption and the bootstrap
SEs. Index terms: equating, delta method, linear
equating, score equating, standard errors of equating.
