Research Methodology
Research Instrument
A tool used to collect, measure, and analyze data related to a research subject.
What is Research Instrument?
A research instrument can be a physical device, a psychological test, a questionnaire, an interview guide, or an observational checklist. It is the specific mechanism by which the researcher gathers empirical evidence.
Why Research Instrument Matters
The quality of the research instrument directly dictates the reliability and validity of the data collected; a flawed instrument yields flawed data.
Example
In a study on atmospheric pollution, a finely calibrated mass spectrometer serves as the primary research instrument.
Common Mistakes
- Developing a new instrument from scratch when validated, existing instruments are available.
- Failing to pilot test the instrument before the main data collection phase.
