  2. Multiple choice - Wikipedia

    en.wikipedia.org/wiki/Multiple_choice

    A well written multiple-choice question avoids obviously wrong or implausible distractors (such as the non-Indian city of Detroit being included in the third example), so that the question makes sense when read with each of the distractors as well as with the correct answer. A more difficult and well-written multiple choice question is as follows:

  3. Optical mark recognition - Wikipedia

    en.wikipedia.org/wiki/Optical_mark_recognition

    The rights to Lindquist's patents were held by the Measurement Research Center until 1968, when the University of Iowa sold the operation to Westinghouse Corporation. During the same period, IBM also developed a successful optical mark-sense test-scoring machine, as documented in US Patent 2,944,734 (filed in 1957, granted in 1960).

  4. Operations research - Wikipedia

    en.wikipedia.org/wiki/Operations_research

    Operations research (British English: operational research) (U.S. Air Force Specialty Code: Operations Analysis), often shortened to the initialism OR, is a branch of applied mathematics that deals with the development and application of analytical methods to improve management and decision-making.

  5. Extended matching items - Wikipedia

    en.wikipedia.org/wiki/Extended_matching_items

    Extended matching items/questions (EMI or EMQ) are a written examination format similar to multiple choice questions but with one key difference, that they test knowledge in a far more applied, in-depth, sense. It is often used in medical education and other healthcare subject areas to test diagnostic reasoning.

  6. Queueing theory - Wikipedia

    en.wikipedia.org/wiki/Queueing_theory

    Queueing theory is generally considered a branch of operations research because the results are often used when making business decisions about the resources needed to provide a service. Queueing theory has its origins in research by Agner Krarup Erlang , who created models to describe the system of incoming calls at the Copenhagen Telephone ...

  7. Optimal control - Wikipedia

    en.wikipedia.org/wiki/Optimal_control

    A dynamical system may also be introduced to embed operations research problems within the framework of optimal control theory. [ 4 ] [ 5 ] Optimal control is an extension of the calculus of variations , and is a mathematical optimization method for deriving control policies . [ 6 ]

  8. Ant colony optimization algorithms - Wikipedia

    en.wikipedia.org/wiki/Ant_colony_optimization...

    In computer science and operations research, the ant colony optimization algorithm (ACO) is a probabilistic technique for solving computational problems that can be reduced to finding good paths through graphs. Artificial ants represent multi-agent methods inspired by the behavior of real ants.

  9. Research question - Wikipedia

    en.wikipedia.org/wiki/Research_question

    A research question is "a question that a research project sets out to answer". [1] Choosing a research question is an essential element of both quantitative and qualitative research . Investigation will require data collection and analysis, and the methodology for this will vary widely.
