obtaining quantitative survey responses accurate informative crucial wide range fields traditional ubiquitous response formats likert visual analogue scales require condensation responses discrete point valuesbut sometimes range options may better represent correct answer paper propose efficient intervalvalued response mode whereby responses made marking ellipse along continuous scale discuss potential capture quantify valuable information would lost using conventional approaches preserving high degree response efficiency information captured response interval may represent possible response rangeie conjunctive set real numbers 3 6 alternatively may reflect uncertainty respect distinct responseie disjunctive set confidence interval report validation study utilizing recently introduced opensource software decsys explore intervalvalued survey responses reflect experimental manipulations several factors hypothesised influence interval width across multiple contexts results consistently indicate respondents used interval widths effectively subjective participant feedback also positive present initial empirical evidence efficacy value intervalvalued response capture interestingly results also provide insight respondents reasoning different aforementioned types intervalswe replicate tendency towards overconfidence representing epistemic uncertainty ie disjunctive sets find intervals representing inherent range ie conjunctive sets wellcalibrated
