MULTIPLE CHOICE

(Redirected from Multiple-choice questions)
:''For the 1974 John Wayne crime drama movie, see McQ.''

'Multiple choice' questions (MCQ) or items are a form of assessment item for which respondents are asked to select one or more of the choices from a list. This type of question is used in education testing, in elections (choose between multiple candidates, parties, or policies), in market research, and many other areas.
Frederick J. Kelly is credited with creating multiple choice questions in 1914 at the University of Kansas. One of the first uses of multiple choice questions was to assess the capabilities of World War I military recruits. Test writers are often trained in Bloom's taxonomy.

Advantages

There are several advantages to the multiple choice style. If item writers are well trained and items are quality assured, this can be a very effective item format.^[1] First of all, if students are instructed on the way in which the item format works and the myths surrounding the assessment type are destroyed, students are found to perform better on the test.^[2] On many assessments, reliability has been shown to improve with larger numbers of items on a test, and with good sampling and care over case specificity overall test reliability can be further increased.^[3]
Multiple choice tests often require less time to administer for a given amount of material than would tests requiring written responses. Even greater efficiency can be created by use of online examination delivery software. Multiple choice questions lend themselves to the development of objective assessment items, however, without author training, questions can be subjective in nature. Because this style of test does not require a teacher to mark the given answers, test-takers are graded purely on their selections, creating a lower likelihood of teacher-student bias in the results. Finally, if test-takers are aware of how to use mark sheets and/or online examination tick boxes their responses can be relied upon with clarity.

Disavantages

Multiple choice tests do have disadvantages. One of these is ambiguity; failing to interpret information as the test maker intended can result in an "incorrect" response, even if the taker's response is potentially valid. The term "multiple guess" has been used to describe this scenario because test-takers may attempt to guess rather than determine the correct answer. A free response test allows the test taker to make an argument for their viewpoint and potentially receive credit.
In addition, even if a student has some knowledge of a question, they receive no credit for knowing that information if they select the wrong answer. However, free response questions may allow a taker to demonstrate their understanding of the subject and receive partial credit. Finally, test takers may be able to rule out answers due to infeasibility. In some cases they may even test each answer individually, especially when dealing with mathematics, thereby increasing the chance of providing a correct answer without actually knowing the subject matter. On the other hand, especially on mathematics tests, some answers are included to actually encourage the test taker to logically rule out responses. An example would be giving the equation $4x^2\; +\; bx=3$ and asking what $b^2$ equals. The test taker should be able to eliminate all answers that are a negative number.
The use of multiple choice questions in certain educational fields is sometimes contested due to some of the negative aspects, whether actual or perceived, but the format remains popular due to its utility and cost effectiveness.

Structure

A factual knowledge style MCQ consists of two parts: the question and the answer options. By contrast, an applied knowledge style MCQ consists of three parts: the stem, the lead-in question, and the answer options. The stem can be a vignette or detailed description which has multiple elements to it. It is as long as necessary to ensure maximum validity and authenticity to the problem at hand. The lead-in question describes what the exam taker must do.
In a medical MCQ the lead in question may ask "What is the most likely diagnosis?" or "What pathogen is the most likely cause?"

Examples

A) 4
B) 10
C) 0.5
D) 1.5
E) 8
