Thus, the exams had a significant increase in the difficulty of the average exam question (Kruskal-Wallis χ = 10.35, df = 2, p = 0.006).
From a viewpoint of the question difficulty, the average difficulty index of the MQs was 0.51 which was a moderate value and close to that of the HQs, 0.53.
Therefore, if the average difficulty of the items is, for instance, 0.00, the average theta for the subjects is expected to be close to this value.
We operationalized test difficulty as the average facility index of the items of the test – the proportion of students that sat the test that answered the question correctly.
In spite of this difficulty in finding the average precision of the automatic extractors due to the variation, for instance, of the test corpora size and other factors, it is verified in contributions such as Cabré et al. [1] and Ioannis et al. [18] that about 80% of the linguistic units extracted by the systems of ATE are effectively validated as terminological units by domain experts.
That requires a lot of mice, of course, but also poses the difficulty of trying to average the responses of different animals over time.
Aid organizations have their ears to the ground and could, without too much difficulty, take the pulse of the average Afghan.
Challenges are the design of the superconducting cavity, the choice of the photocathode type, its life time, a possible cavity contamination, the difficulty of coupling high average power into the gun, and, finally, the risk of beam excitation of higher-order cavity modes.
The location of point 0 in the scale is arbitrary, although it is usually placed in the average difficulty of the items.
As the identification constraint, the average difficulty of the items is assumed equal across cohorts.
