RESPONSE ERROR AND REALITY IN GEOGRAPHIC INVESTIGATION

The effect of response and nonresponse errors on the results of research is more dangerous and distroting of reality than the sampling error, since the exact amount of error in resronse nonresponse errors cannot be determined. Therefore, it is very essential that an adequate concern be given to response nonresponse errors in geographic investigation. The fundamentality of such concern should be emphasized at a stage of geographic research where a growing interest among geographers is geared toward the behavioral aspects of spatial phenomena. Such behavioral characteristics are emphasized in many recent studies such as that of Cox and Golledge,' Olsson and Gale,' Rushton,' Pred,' and many others.
