  • The sample must truly represent the population.

  • The population must be homogeneous.

What is element research 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.

What is an ideal sample?

A good maximum sample size is usually around 10\% of the population, as long as this does not exceed 1000. For example, in a population of 5000, 10\% would be 500. In a population of 200,000, 10\% would be 20,000. Sampling more than 1000 people won’t add much to the accuracy given the extra time and money it would cost.

  • Select a sampling frame.

What are established by a good sample in research?

Which of the following are the characteristics of a good sample in research?

Practical: simple and follow the field condition. Accuracy and precision: it is valid from every perspective. The sample design should be such that it results in a small sampling error. It should be viable in the context of budgetary constraints of the research study.

What is a data example?

Data is defined as facts or figures, or information that’s stored in or used by a computer. An example of data is information collected for a research paper. An example of data is an email. Facts or figures to be processed; evidence, records, statistics, etc.
