Question

Write short notes on questionare

Answer 1

A questionnaire is a research instrument consisting of a series of questions (or other types of prompts) for the purpose of gathering information from respondents. The questionnaire was invented by the Statistical Society of London in 1838.[1][2]

Although questionnaires are often designed for statistical analysis of the responses, this is not always the case.

Questionnaires have advantages over some other types of surveys in that they are cheap, do not require as much effort from the questioner as verbal or telephone surveys, and often have standardized answers that make it simple to compile data. However, such standardized answers may frustrate users. Questionnaires are also sharply limited by the fact that respondents must be able to read the questions and respond to them. Thus, for some demographic groupsconducting a survey by questionnaire may not be concrete.

TypesEdit

A distinction can be made between questionnaires with questions that measure separate variables, and questionnaires with questions that are aggregated into either a scale or index. Questionnaires with questions that measure separate variables, could for instance include questions on:

preferences (e.g. political party)behaviors (e.g. food consumption)facts (e.g. gender)

Questionnaires with questions that are aggregated into either a scale or index, include for instance questions that measure:

latent traitsattitudes (e.g. towards immigration)an index (e.g. Social Economic Status)

ExamplesEdit

A food frequency questionnaire (FFQ) is a questionnaire the type of diet consumed in people, and may be used as a research instrument. Examples of usages include assessment of intake of vitamins or toxins such as acrylamide
