Definition of an Instrument Used in Research

Types of Research Instruments

Research instruments are tools or methods used by researchers to collect data and gather information in order to answer research questions or test hypotheses. There are several types of research instruments that can be used in different research studies, each with its own strengths and weaknesses. Some of the most common types of research instruments include:

Surveys

Surveys are questionnaires that are used to collect data from a large number of people. They can be administered in person, over the phone, or online, and can include both closed-ended questions (i.e., questions with a set of pre-determined responses) and open-ended questions (i.e., questions that allow for free-form responses). Surveys are often used in social science research to gather information about people’s attitudes, beliefs, and behaviors.

Interviews

Interviews are conversations between a researcher and a participant or participants. They can be conducted in person, over the phone, or online, and can be either structured (i.e., follow a predetermined set of questions) or unstructured (i.e., allow for free-flowing conversation). Interviews are often used in qualitative research to gather in-depth information about a particular topic or phenomenon.

Observations

Observations are the systematic collection of data through direct observation of behaviors, phenomena, or events. Observations can be conducted in natural settings (i.e., observing behavior in its natural context) or controlled settings (i.e., observing behavior in a laboratory or other controlled environment). Observations are often used in social science research to gather information about social interactions, behaviors, and cultural practices.

Case Studies

Case studies are in-depth investigations of a particular individual, group, or situation. They often involve the collection of data through multiple methods (e.g., interviews, observations, document analysis), and are used to gain a comprehensive understanding of a particular phenomenon or situation. Case studies are often used in qualitative research to explore complex issues or phenomena in depth.
