Includes dataset of two surveys and an interview for a study to understand accessibility and human factors issues in online crowd work. Participants responded to the surveys through Amazon Mechanical Turk and provided information on demographics as well as how they engage in online work on the platform. The dataset contains data from the two surveys and an interview (can be viewed on the different tabs). Garbage data has been removed from the dataset (in survey 2). The publication that emerged from analysing the dataset can be found at https://doi.org/10.1145/3411764.3445291 (in press)
