For example, item No. 1, with more than 300,000 citations: Protein measurement with the folin phenol reagent.
For example, item 15 reads "Humans exist today in essentially the same form in which they always have".
For example, Item Response Theory, a popular approach to psychological measurement, employs a variety of models to evaluate the validity of questionnaires.
For example, item a gets 2 facings with a stock of 4 units each, resulting in a total quantity of (2 cdot 4=8) units.
For example, Item Q6.2_1, in addition to its expected relationship with obstacles to getting support, also showed a comparatively small but significant positive relationship with perceived knowledge.
For example, item difficulties are computed as the proportion correct and item discrimination is obtained as item-total correlations in CTT.
This provides an opportunity to study item misfit due to, for example, item position effects (e.g., items that are at the end of the booklet can be more difficult due to either speededness or fatigue effects; see, for example, Debeer and Janssen 2013).
For example, Item 6 on the GeDI asks students whether a biologist would agree or disagree with the (incorrect) statement that "The fact that individuals that were best suited to the environment had a higher rate of survival contributed to genetic drift" (Supplementary Materials in Price et al. 2014).
For example, Item 1 in the GeDI asks students whether a biologist would agree or disagree with the (correct) statement that "Genetic drift is more pronounced in the [founding] island population than the [larger] mainland population in these first few generations" (Supplementary Materials in Price et al. 2014).
For example, item Chip42 ("explaining our family situation to friends and neighbors so that they understand") and Chip44 ("chatting with other people/parents in the same situation") have a clear communicative intention directed to people other than family members for support.
