This paper briefly describes four methods of time allocation study and examines the use of one of them, the "random spot-check," in the field. Time allocation methods provide quantitative data that is particularly useful for environmental or ecological research in anthropology. Practical problems of implementation, however, often override their theoretical usefulness. The "random spot-check" technique can be hindered by unforeseen time constraints and social considerations. The insightful data generated through this field method, however, may make it worthwhile for the researcher to attempt to overcome its practical limitations and include it in his or her research project.
