There were no differences between the direction of the tester's visual regard and raters' mean scores for each variable.
The two primary testers examined 67% of the infants.
Unsurprisingly, this has led to better correlation between testers.
All measures were administered to the children individually by trained testers who were familiar with testing children in these age groups.
Language testers are also likely to be interested in self-contained individual tasks.
Moreover, use two trained testers and each measure four times, remove the largest and smallest from eight measurements and take the average.
Moreover, the specification of the testers' expectation leaves students with adequate time to prepare themselves for taking the test.
We finally show that the same results hold even in the case of two-sided error property testers.
