There are a lot of ways to conduct research and collect information, but one way that makes it really easy is by doing a survey. A survey is defined as a brief interview or discussion with individuals about a specific topic. The term survey is unfortunately a little vague, so we need to define it better. The term survey is often used to mean 'collect information.' For instance, you may imagine a researcher or a television scientist saying, 'We need to do a survey!' (I know, riveting television).
So, besides our definition above, survey also means to collect information. We have our first definition of a brief interview, and we have a second definition of collecting data. There is a third definition for survey. This third definition of survey is a specific type of survey research. Here are the three specific techniques of survey research:
Questionnaires - a series of written questions a participant answers. This method gathers responses to questions that are essay or agree/neutral/disagree style.
Interviews - questions posed to an individual to obtain information about him or her. This type of survey is like a job interview, with one person asking another a load of questions.
Surveys - brief interviews and discussions with individuals about a specific topic. Yes, survey is also a specific type of survey, to make things even more confusing. A survey is a quick interview, with the surveyor asking only a few questions.
