web experiment participants randomly assigned two semantic differentials either made discrete 5point ordinal rating scales continuous visual analogue scales vass 250 gradations respondents adjusted ratings vass often maximize precision answers beneficial effect data quality side effects like differences means higher dropout nonresponse higher response times observed overall combination semantic differentials vass results number advantages potential research discussed
