A data set containing data from Dohle and Siegrist (2014)'s Experiment 1 that can be used to conduct within-subject joint-significance test. In this experiment, researchers are interested in the effect of name complexity on willingness to buy a drug. The specific hypothesis is that complex drug names are perceived as more hazardous, which makes someone less likely to buy the drug. Researchers used a within-subject design.

This data set is in a long-format, see mdt_within to conduct a within-participant mediation analysis with this data set.



A data frame with 44 rows and 4 variables:


Participant number.


Name of the drugs ("simple" vs. "complex").


Mean estimated hazardousness.


Mean willingness to buy.
