MY WORK

The BALLABEAT Case Study

Smart Strategies for a Health-Conscious Future

During the Google Data Analytics course, I had the opportunity to work as a junior data analyst in a simulated real-world business environment for a wellness technology company called Bellabeat. Bellabeat is a company that specializes in smart devices for women’s health and has ambitious plans to expand globally — and I played a part in this project.

🧩 The Challenge

My task was to analyze user behavior based on a public Fitbit dataset and draw conclusions about Bellabeat users from this data. The ultimate goal was to formulate strategic recommendations that could help Bellabeat grow and better serve its customer segments on a marketing level.

🛠️ What I Did

During the project, I went through the entire data analysis process:
  • Formulating questions: What do the trends indicate? How do people use smart devices in their daily lives?
  • Data preparation and cleaning: I examined the daily activity, sleep habits, step count, calorie burn, and other key variables of Fitbit users.
  • Analysis and visualization: I highlighted habits and behavior patterns that could be relevant to Bellabeat's target audience.
  • Developing strategic recommendations: I formulated data-driven suggestions on how Bellabeat can communicate more effectively, which features to highlight, and how to target its users more consciously.

📈 Why R?

The R programming language stands out in the fields of statistical analysis and data visualization. Its rich package ecosystem – including tools like tidyverse, ggplot2, and shiny – enables quick, intuitive data processing and the creation of stunning visualizations with minimal code. Additionally, R excels in its design for data-centric thinking, allowing for complex analyses to be executed with short, clear scripts. This makes it especially useful in fields such as research, healthcare, and academic projects, where precision and clarity in data handling are paramount.

📈 Marketing

**Recommendation for Ballabet Stakeholders**

  • If users sleep little, it is worth promoting sleep tracking features.
  • At which part of the day do they burn the most calories? Reminders sent during active periods could increase engagement.
  • For those with a sedentary lifestyle, activity-boosting campaigns should be created (e.g., exercise challenges).
  • Those who show higher activity levels could be encouraged and rewarded, for example, with membership sign-ups.
  • Those who show less activity should also be motivated, with smaller commitments, mentorship programs, membership sign-ups, etc.

💡 What I Learned

This project not only deepened my data analysis skills (handling data sources, cleaning, visualization, drawing conclusions) but also greatly contributed to my understanding of marketing and business thinking. Based on my data, I was able to identify certain daily habits that could be crucial in product usage – and these insights can directly inform real marketing decisions.
