Additionally, workshops and gatherings of researchers around the world take place to discuss current evaluation techniques and advance the field of experience research in the area of transportation. An important professional venue for this work is AutomotiveUI, the International Conference on Automotive User Interfaces and Interactive Vehicular ...
Survey methodology is "the study of survey methods". [1] As a field of applied statistics concentrating on human-research surveys, survey methodology studies the sampling of individual units from a population and associated techniques of survey data collection, such as questionnaire construction and methods for improving the number and accuracy of responses to surveys.
