What is a Questionnaire?

A questionnaire is a set of written questions used to gather information from respondents. It is a tool or instrument that can be used in various contexts—including surveys, interviews, assessments, and feedback forms.

The main purpose of a questionnaire is to collect standardized data in a structured format. It can exist as part of a survey or function independently as a standalone form.

Key Characteristics of a Questionnaire:

• Typically contains a mix of close-ended and open-ended questions
• Designed for clarity, structure, and ease of use
• Can be used online, offline, on paper, or digitally
• Does not always involve data analysis or research methodology

What is a Survey?

A survey is a research method that involves collecting and analyzing data from a predefined group of respondents. It uses a questionnaire as the primary tool to gather responses—but also includes the methodology, distribution strategy, and analysis.

Surveys are often used for:

• Customer satisfaction measurement
• Market research
• Employee engagement surveys
• Customer experience management

Key Characteristics of a Survey:

• Includes a questionnaire but goes beyond just the questions
• Involves a defined sampling method and data collection strategy
• Aims to uncover insights, patterns, and trends
• Uses tools for data visualization, analysis, and reporting

Responsly supports powerful distribution methods, from email surveys and WhatsApp surveys to kiosk surveys and popup surveys.
