Races are rated by difficulty: Category 1 (Allen Clark, Ascutney, Burke, Greylock and Okemo), Category 2 (Whiteface and Equinox), and hors category, or out of category (both Mount Washington events).
The Rater Team could not agree on the rating for this question, because they disagreed about its level of difficulty (category: Difficulty).
Rasch analysis was used to examine the Chinese version of ODI 2.1 for unidimensionality, item difficulty, category function, differential item functioning, and test information.
Self-reports of day time dysfunction was less frequent, with 6.1% (155) of students in the highest difficulty category while the habitual sleep efficiency of less than or equal to 74% was reported by 19.4% (418) of the participants.
It is important to note, though, that most authors failed to present data that allowed them to unpack or characterize each difficulty category into subcategories that would be more useful to instructors.
The Difficulty category reflects participants' thinking about whether a question was expected to be challenging for students, whether the concepts referenced in a question are generally hard to apply, and how students typically perform on similar questions.
In web pages dedicated to each target, we provide basic sequence and structure information, list discrepancies between the PDB file and the target sequence, specify boundaries of evolutionary domains, perform sequence and structural classification of these domains, and attribute them to prediction difficulty category.
16 Difficulty level category Others includes words over level 8, non-English words, and misspelling.
