Data: Ternary Risky Choices (Regenwetter & Davis-Stober, 2012)

Description

Raw data with choice frequencies for all 20 paired comparison of 5 gambles a, b, c, d, and e. Participants could either choose "Option 1", "Option 2", or "indifferent" (ternary choice). Each paired comparison (e.g., a vs. b) was repeated 45 times per participant. The data include 3 different gamble sets and aimed at testing whether people have transitive preferences (see Regenwetter & Davis-Stober, 2012).

Usage

regenwetter2012

Format

A matrix with 22 columns:

participant:

Participant number

gamble_set:

Gamble set

a>b:

Number of times a preferred over b

b>a:

Number of times b preferred over a

a=b:

Number of times being indifferent between a and b
