The main advantages of the technique of the survey:

1. It can quickly gather a lot of information because of the large number of people and can encompass the variety of questions that may include the questionnaire.

The survey presents distinct advantages over other techniques of data collection; However, like every technique also it has some disadvantages, among which we highlight:

1. In some cases it can be costly; for example, when you need to train enumerators, move them and pay them a salary or bonus.

The process of conducting a survey starts with the planning of this, including the establishment of the objectives sought to achieve with the survey, the determination of the population or universe to study, identifying the information required for this, questionnaire design and calculation of the sample.

The universe or population survey is the total set of people with similar characteristics which are desired information needed for research; for example, in the case of a survey conducted by a company, the population usually consists of consumers who make up your target market, while information that is required of these is usually made up their tastes, preferences, desires, habits consumption, etc.

A population is usually composed of a large number of people, so not to have to survey all these, thereby saving time and money, usually only it surveys a number of people representative of the population, which is often obtained Through a statistical formula and known as a sample.
Once the survey planned proceeds to make it effective, including the selection, recruitment and training of interviewers, gathering the required information, accounting, coding and analysis of this, and the preparation of the report, if applicable.

Here is a summary of the steps to perform a survey:

  • Setting objectives of the survey: first clearly define the objectives that seek to achieve with the survey to be carried out.
  • Determination of the population or universe: the population or universe is determined to study (the total set of people which want to obtain information).
