The Kuder-Richardson formula (21) as a split-half coefficient, and some remarks on its basic assumption
- 631 Downloads

The basic assumption employed is shown to be sufficient to justify the various assumptions used in derivations by other authors. Some of the implications of this assumption are discussed.
