Questionnaires have been used since the 19th century. Often used as a method for collecting information, questionnaires were first developed in London in 1838.

Questionnaires are usually used for collecting data from the respondents through a series of questions and other prompts set by the organization conducting such experiments.

Questionnaires are not necessarily statistical data, but they do act as an effective alternative for surveys, since they are cheap and can be widely used to reach within people in a short period of time.

These are usually used to get a standardized answer rather than a specific answer seen in other questionnaire types of statistical data collection.

Questionnaire Types Advantages Disadvantages

Types of Questionnaires:

Based on the type of questions used, questionnaires are as follows:

1. Structured questionnaire:

Comes under quantitative research. It includes the low number of researchers and the high number of respondents. They are also called as closed questionnaires. They usually include answers such as very bad, bad, good, very good and so on.

  • They have a definite and concrete questions
  • They have to be prepared well in advance so as to ask as much questions and receive info from the respondent.
  • A formal enquiry is initiated.
  • Supplements and checks the previously accumulated data.
  • Commonly used in for social and economic problems, to study about the changes caused due to change in policies, laws etc.

2. Unstructured questionnaire:

A version of qualitative survey. They are usually based around more open questions. Open questions also means recording more data as the respondents can point out what is important for them, in their own words and methods. But it is more difficult from the researcher’s side, since it does not give the correct idea of the topic and moreover proper understanding of the data is needed.

  • Usually used at the time of an interview.
  • Doesn’t require much planning and time.
  • More flexible for applying in many areas.

The respondents are asked to scale the answers based on a given rating prescribed by the question.

Depending on the type of format used in questionnaires, they are divided into the following.

Open format questions:

By using such questions, the respondents do not have to follow the criteria for answering questions and he/she can truly express their beliefs and suggestions. An ideal questionnaire is a type of questionnaire that includes open ended questions and also have feedback and suggestions for future improvements.

Closed format questions:

Multiple choice questions comes under this category. The user is restricted to answer their opinions through the options that is set by the surveyor. Hence, these are also called as close ended questions. One of the main advantages of using closed ended questions is the ease of doing preliminary analysis. These are usually used to find opinion about known questions and answers. They are usually used to track the status and the improvements of organisations and companies.

Closed ended questions are of various types:

1. Leading questions:

These type of questions force a definite type of answer from the audience. In such a question, all kind of answers are equally likely. The answers can vary from bad, very bad to good and very good. These are usually used to collect information from the users in very limited words.

2. Importance questions:

3. Likert questions:

These questions show how much the customer agrees to a certain topic and how much it impacts the respondent.

4. Dichotomous questions:

These questions ask the respondents only a yes or no answer. Hence, it makes it difficult to analyse beyond the yes and no answer.

5. Bipolar questions:

Such questions have answers that are in the extreme case. The respondents are required to ask to rate the question between these two extremities.

6. Rating scale questions:

In such questions, the respondents are asked to rate a particular issue between the ratings of good and bad. Such questions have even number of choices, so as to prevent selecting the middle option all the time.
