Types of data collection

  • Sample Survey
  • Administrative Data

Data can be collected using three main types of surveys: censuses, sample survey, and administrative data. Each has advantages and disadvantages. As students, you may be required to collect data at some time. The method you choose will depend on a number of factors.

Census

A census refers to data collection about every unit in a group or population. If you collected data about the height of everyone in your class, that would be regarded as a class census. There are various reasons why a census may or may not be chosen as the method of data collection.

Sample survey

In a sample survey, only part of the total population is approached for data. If you collected data about the height of 5 students in a class of 30, that would be a sample survey of the class rather than a census. Reasons one may or may not choose to use a sample survey include:

 

Administrative data

Administrative data are collected as a result of an organization’s day-to-day operations. Examples include data on births, deaths, marriages, divorces and car registrations. For example, prior to being issued a marriage license, a couple must provide the registrar with information about their age, sex, birthplace, address and previous marital status. These administrative files can be used later as a substitute for a sample survey or a census.
