Stability vocabulary coefficient was /0.97/ and Stability of individuals coefficient was /0.68/. It turns out that the test covered how difficult vocabulary, vocabulary difficulty value ranged between/2.48/and/2.05/logt. And evaluated the ability of individuals between 1.26 and 2.1.13 logitech. The values of all vocabulary were included in a statistical value corresponding to the Rush model.
