data("treatment")

Format

A data frame with 235 observations on the following 4 variables.

cond

Condition, referring to the way that statistical information was presented (see details).

choice

Treatment preference on an ordinal, 6-level scale from "definitely angioplasty" to "definitely bypass".

effectiveness

Participant ratings of the importance of treatment effectiveness on treatment choice (1 is extremely unimportant; 6 is extremely important).

invasiveness

Participant ratings of the importance of treatment invasiveness on treatment choice (1 is extremely unimportant; 6 is extremely important).

Details

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.
