Test Specifications
Your test should be made up of 10 multiple-choice items, all assessing the construct of “reliability” (please note: all the items you create should be about the topic of “reliability”; therefore, your test should assess individuals’ knowledge of reliability; you are not simply creating a reliable test), with four answer choices for each item. Use knowledge, principle, and application item types. Follow the item writing guidelines presented in the “Considerations For Writing Quality Test Items” video.
Difficulty Index and Discrimination Index
Use the hypothetical data provided below to calculate a difficulty index and discrimination index for each item (using the correct response you have identified for each item).
