The Crowd-sourced Fitbit datasets 03.12.2016-05.12.2016 was part of a study done by Brinton J, Keating M, Ortiz A, Evenson K, Furberg R for a study titled: Establishing Linkages Between Distributed Survey Responses and Consumer Wearable Device Datasets: A Pilot Protocol. Their goal was to create methods for remotely collecting data and establishing a link between self-reported survey responses and biometric data from consumer wearable devices, resulting in a de-identified and linked dataset.

As described by the research team, a total of 30* participants who use a Fitbit were recruited on Mechanical Turk Prime and asked to complete a short online self-administered questionnaire.

The participants were asked to connect their personal Fitbit activity tracker to an online third-party software system, called Fitabase, which allowed the research team to access a 1 month’s retrospective data and 1 month’s prospective data, both from the date of consent.

The original complete data is uploaded to Zenodo by Furberg, Robert; Brinton, Julia; Keating, Michael ; Ortiz, Alexa, on 31/05/2016 and it was divided into two folders, each folder contains roughly one month's worth of user-submitted data:

1. mturkfitbit_export_4.12.16-5.12.16.zip - (1 month’s prospective data)
2. mturkfitbit_export_3.12.16-4.11.16.zip - (1 month’s retrospective)

The dataset uploaded to Kaggle by Möbius is only the first folder named (mturkfitbitexport4.12.16-5.12.16.zip), which contains data from 12/04/2016 to 12/05/2016, and this dataset contains the retrospective data (mturkfitbit_export_3.12.16-4.11.16.zip).

This notebook contains a cleaned merged dataset that spans the dates 12/03/2016 to 12/05/2016. If you prefer not to use the notebook output and want to clean the data yourself, keep in mind that the file dailyActivity merged.csv was not properly merged and does not contain all of the data available in the minute CSV files. For more information on this check, see 4.1.3 in this notebook.
