A sizable fraction of workers provides hasty, wrong answers in crowd-sourced tasks

The collected data represent the answers reported by crowdsourcing workers on Amazon Mechanical Turk (AMT). Three type of tasks, HITs where published on AMT, namely, Color, Majority and Count.

Each file represents the deanonymized answers of 100 workers reporting their answers to the each task. The experiments where repeated after seven months and those data are included as well. The ending in the file name *batch2, reveals whether data refer to the first or second round of experimentation.
