Surveys and Questionnaires
The terms survey and questionnaire are often used interchangeably, however there is a significant difference between the two.
Survey – the general collection, recording, and analysis of information on a specific topic from a group of individuals in order to measure opinions, thoughts, or experiences.
Questionnaire – a form containing a set of written questions designed to obtain statistically useful information from individuals.
These two are similar in that they both are methods used to acquire data from respondents based on questions. However, a survey encompasses all aspects of the research process, including design, survey construction, sampling method, data collection and analysis.
A survey gathers the results of multiple questionnaires from a set group so that a statistical analysis can be conducted on the aggregated data. A questionnaire, on the other hand, is just a type of survey. Other types of surveys include face-to-face interviews, phone interviews, and polls.
