Data from Experiment 3 in Sundh et al. (2023)
Description
Participants made probability judgments of the format: “What is the probability that the weather is [X] on a random day in England?". Various weather events were used, and the queries included both marginal events, conditional events, conjunctions, and disjunctions. The total set of 20 unique queries formed a block within which the presentation order was randomized for each participant. The experiment consisted of three blocks, so that all participants responded to each unique query three times.
