# What is distractor analysis?

**analysis**that is often reported is the

**distractor analysis**. The

**distractor analysis**provides a measure of how well each of the incorrect options contributes to the quality of a multiple choice item. Once the item

**analysis**information is available, an item review is often conducted.

In respect to this, what is a distractor on a test?

**Distractors** are the incorrect answers in a multiple choice question. Choosing your **distractors** poorly can make your multiple choice questions much easier or harder than you may have intended.

Beside above, how do you calculate distractor efficiency? **Distractor Efficiency** and Its Relation With Bloom's Taxonomy In order not to penalize this type of item, the expected percentage of choices was **calculated** assuming that the choices were uniformly distributed: q = (100 -P-value)/k, where k is the number of incorrect alternatives.

In respect to this, what is distractor efficiency?

**Distractor Efficiency** and Its Relation With Bloom's Taxonomy A functional **distractor** was defined as one that exhibited negative discrimination and was selected by at least 5% of the participants.

What is discrimination index and its formula?

**The Discrimination Index** (D) is computed from equal-sized high and low scoring groups on **the** test. Subtract **the** number of successes by **the** low group on **the** item from **the** number of successes by **the** high group, and divide this difference by **the** size of a group. **The** range of this **index** is +1 to -1.
