Datasets

Real-world data can be difficult to obtain. Here I share the datasets collected as part of my research.

Mobile App User Dataset

I surveyed 10,208 people from more than 15 countries on their mobile app usage behavior. The countries include USA, China, Japan, Germany, France, Brazil, UK, Italy, Russia, India, Canada, Spain, Australia, Mexico, and South Korea.

We asked respondents about: (1) their mobile app user behavior in terms of mobile app usage, including the app stores they use, what triggers them to look for apps, why they download apps, why they abandon apps, and the types of apps they download. (2) their demographics including gender, age, marital status, nationality, country of residence, first language, ethnicity, education level, occupation, and household income (3) their personality using the Big-Five personality traits

This dataset contains the results of the survey.

Detailed descriptions about the project and how I collected the data can be found in my TSE paper (3MB).
