A data frame with 242 observations on the following 3 variables.
task
a variable with responses 0 and 1. If 0 task
is Boeing stock
, if 1 task
is Sunday weather
.
location
a numeric vector of the average of the lower estimate for the event not to occur and the upper estimate for the event to occur.
difference
a numeric vector of the differences of the lower and upper estimate for the event to occur.
All study participants were from the first or second year, none of the participants had an in-depth knowledge of probability.
For the sunday weather task see WeatherTask
. For the Boeing
stock task participants were asked to estimate the probability that
Boeing's stock would rise more than those in a list of 30 companies.
For each task participants were asked to provide lower and upper
estimates for the event to occur and not to occur.
The task
variable that was a qualitative variable was transformed into a quantitative variable to be used by the package functions.#'
