Element sampling

Element sampling, or direct element sampling, is a sampling method whereby every unit (i.e. person, organisation, group, company etc.) has an equal chance of being selected to be included in the research sample. This is possible when we are able to identify and contact every individual in a target population – something which is often unlikely due to cost implications or impracticality.

Element sampling is a broad term which can encompass both simple random sampling and systematic sampling. This means that the sample can either be selected using a random number generator or by randomly selecting the first respondent and picking every nth item after that (whereby n is the size of the interval). As a result, the sample should represent the characteristics of the entire population. These processes then confirm that the data collected is statistically significant and applicable to the population.

Element sampling is used in market research when businesses require insights into target markets, trends and consumer preferences. It is used to acquire reliable, unbiased results which will reflect consumer behaviour. This type of sampling is most commonly used for selecting samples for surveys and interviews in the education and medical and healthcare sectors.

The importance of element sampling in market research is highlighted through the need for unbiased, accurate and generalisable data. It ensures businesses have a thorough understanding of the market they are operating in which will result in the making of informed decisions. There is a chance of unrepresentative groupings being selected due to the lack of control from the researcher. However, the added benefit of efficiency makes element sampling a good choice for gathering data from a large population when a sampling framework (a list of the individuals in the target population) is available.
