The term "field-notes" refers to the notes or observations taken by researchers while conducting experiments, gathering data, or conducting surveys in the field. Some common synonyms for field-notes include observation notes, research notes, survey notes, and data notes. These terms all refer to the same concept of recording information in the field, but each one may be used in specific contexts. Observation notes are typically used in qualitative research, while research notes are more commonly used in quantitative research. Survey notes refer specifically to observations made during a survey, while data notes refer to any notes relating to collected data. Regardless of the term used, field-notes are an essential part of any research or data collection process.
