The main difference between the parallel forms and splite-half techniques for assessing reliability is that
A) the parallel forms techniques involves testing participants on two separate occasions and the split-half technique does not.
B) items are arbitrarily divided for comparison in the parallel forms procedure but this is not true for the split-half technique.
C) a high positive correlation between scores reflects good reliability for the parallel forms procedure but a high negative correlation is indicative of good reliability for the split-half procedure.
D) split-half correlations reflect stability whereas parallel forms correlations do not.

The main difference is that the parallel forms technique involves administering two different but equivalent versions of a test to the same group of participants on two separate occasions to assess consistency, while the split-half technique involves dividing a single test into two parts and comparing the scores of these two halves within the same test administration to assess internal consistency.
