In the market research industry, LOI stands for “Length of Interview.” It refers to the estimated or actual duration of a survey or interview conducted with a respondent. LOI is an important factor in the design and planning of research, as it helps researchers determine the appropriate methods for data collection, manage respondent engagement, and ensure the survey fits within participants’ time expectations. A well-defined LOI is essential for maintaining the quality of data while respecting the time constraints of the respondents.
