Sentence examples for simulated items from inspiring English sources
"simulated items" is a correct and usable phrase in written English
It refers to items or objects that have been created or replicated in order to imitate or mimic something else. Example: The participants in the experiment were asked to interact with the simulated items on the computer screen, which were designed to replicate real-life shopping scenarios.
Since measures with mean trait levels of 0 or 1 logit were simulated, items in this range of difficulty would be most frequently administered.
Prior to performing CAT simulations, response data for all 100 items in the simulated item banks described above were generated for a total of 3000 simulees in each iteration.
Using IRT as theoretical basis of our simulations, we simulated 27 items across the entire phenotypic continuum, with difficulty parameters ranging from −4 to 3.8, with steps of.3 (assuming a standard normal latent trait), and fixed discrimination parameters of 1 (i.e., Rasch model).
In this paper, we quantify the amount of error introduced by scoring the PAM across the full possible range of 1 to 12 simulated missing items.
Similarly, power rates are computed as the proportion of items that are simulated as DIF items that are also flagged as having DIF.
Item usage was comparable for items simulated with DIF (Med=557.5, IQR = 123 1315) and non-DIF items (Med = 551, IQR = 117 1320).
He traveled to Singapore, which has a well-known spotless veneer, investigating the phenomenon and producing Rubbish, a series of eight colored pencil-on-paper illustrations that simulate discarded items like plastic chip bags and paper wrappers. .
Any one booklet contained a total of 45 items and a total of 105 items were simulated for each group (15 items per block × 7 booklets).
1PL = one-parameter item response model; 2PL = two-parameter item response model; CAT = computerized adaptive testing; DIF = differential item functioning; DIF% = percentage of items simulated with DIF; FP% = percentage of false positive DIF results; IRT = item response theory; TP% = percentage of true positive DIF results; θ = person measure.
Non-DIF-item response data were generated using the estimated parameters in Additional file 1. Items simulated to exhibit mode effects (DIF) were randomly selected according to the percentage of DIF items (10% or 30%) for the specified simulation condition.
The original item difficulties from the LV 2011 were used to simulate the item responses.
