For this subscale, the curve has one peak, around the scores ranging from 22 to 32, indicating that the scale is more informative for patients with lower scores, however the test information function increases again from a total score of 60, indicating the subscale contains many discriminating items for patients with higher scores.
"Until the test information finds its way back to the classroom, you're not going to get the impact people really want," Ms. Baker said.
The testbed server of HINT collect, parse and understand all the test information, and then reconstruct the sensor network behavior.
Version B provided 91.01 % of information for this skill range, as shown by the test information curve (Fig. 2).
The test information and analytical data can be stored to help analysts perform real-time analysis in SRAMAP.
For this skill range, version A provides 85.4 % of the total information provided by the 2PL model, as shown by the test information curve (Fig. 1).
They illustrate at which level of the latent variable (theta) the test information is maximal and thereby, also where measurement precision is highest [49].
In addition, there is a relationship between the Type I error rates and the test information function; Type I error rates become larger as information goes down.
Table 4 represents the test information for half-scale girders under fatigue loading including the loading rate, load range, and number of fatigue loading cycles.
The test information functions of the powerlessness scale (Additional file 1: Figure S1) and meaninglessness scale (Additional file 2: Figure S2) were very similar regardless of the respective DIF group.
To explore the inflated Type I error rates of the item-fit residuals, Fig. 2 shows the Type I error rates as a function of (theta) and the test information functions for the four NAEP data sets.
