Quantitative methods III

Stevens’ scales of measurement are often used in texts outlining statistical approaches for geographers. However, it is sometimes overlooked that these are not universally accepted, and indeed the theory surrounding them is contested. This progress report reviews the key ideas of these scales, and discusses a number of the problems they raise – most notably the fact that certain kinds of data are omitted. The value of an axiomatic approach to measurement scales and appropriate statistical techniques is then considered. The report concludes by considering further areas where these ideas may be developed.
