Primary data is information provided directly to the researcher or investigator through responses or observation.

Secondary data is information available to the researcher or investigator from previous research and studies.

Primary data can be collected through the administration of questionnaires and interviews or through observation of aspects under study.

Questionnaires are a set of questions that are administered to the respondents where they communicate their opinions through writing or checking boxes. For example, research survey questionnaires are classified into three types:

  • Open ended questionnaires- where the respondent is free to answer the questions in their own words
  • Closed ended questionnaires- where the respondent is restricted to the researchers set choices when answering the questions
  • Hybrid questionnaires- where the questionnaire employs both open and closed ended questions

Interviews are also a set of questions which are administered orally, and the researcher is tasked with writing down (or tape recording) the responses made by the respondents.

Observation entails recording what is observed regarding the object under study.
