La calidad de la encuesta en la sociedad digital: avances y retrocesos

The increasing digitalization of developed societies contributes to reduce research costs, although it does not always meet quality criteria. This article offers an overview of advances in survey methodology after reviewing recent empirical research published in specialized journals. Special emphasis is placed on online survey and mixed survey methods, along with the handicaps of data collection using mobile devices. Deficits in the representativeness of the samples were detected due to coverage errors, non-response errors and the application of non-probabilistic sampling and volunteer panels. Also, there are deficits in the representativeness of the data due to measurement errors, to which recent technological advances contribute to their reduction. Each error is accompanied by consensual actions to reduce its impact on the quality of the survey.
