Item Analysis is probably the most important tool for increasing test effectiveness. In order to write items that accurately and reliably measure what they’re intended to, you need to examine participant responses to each item. You can use this information to improve test items and identify unfair or biased items.
So what’s the process for conducting an item analysis? What should you be looking for? How do you determine if a question is “good enough”?
