Experimental data in which participants were presented with statistical information about two treatments for chest pain, then asked about their preference for a treatment.
A data frame with 235 observations on the following 4 variables.
Condition, referring to the way that statistical information was presented (see details).
Treatment preference on an ordinal, 6-level scale from "definitely angioplasty" to "definitely bypass".
Participant ratings of the importance of treatment effectiveness on treatment choice (1 is extremely unimportant; 6 is extremely important).
Participant ratings of the importance of treatment invasiveness on treatment choice (1 is extremely unimportant; 6 is extremely important).
The data were taken from Hulsey (2010). Study participants were asked to make a hypothetical decision between two treatments for chest pain: bypass surgery or balloon angioplasty. Bypass is generally more effective, but it is also more invasive and has a longer recovery time.
Conditions were defined by the way participants received statistical
information concerning the two treatments. In condition
pictograph, participants viewed
visual information via a pictograph. In condition
statistics, participants view numerical information.
