Bellabeat Case Study
This case study analyzes fitness tracker data to understand user behavior and provide strategic recommendations for Bellabeat, a wellness technology company. Using R programming, I examined how people use fitness trackers, identifying patterns in daily activity, sleep habits, and calorie consumption. The analysis reveals key insights about user engagement and health behaviors that inform product development and marketing strategies. This project demonstrates how data analysis can drive business decisions in the competitive wellness technology market.

Project Details
Goal & context. This R-based case study uses Fitbit-style fitness tracker data to understand how users behave with wearable devices and to generate actionable recommendations for Bellabeat. The work was carried out in Kaggle with the aim of informing product and marketing decisions through clear, evidence-based insights on activity, sleep, and engagement.
Data cleaning & preparation. Raw Fitbit data (daily and intraday steps, calories, sleep, intensity) was loaded in R; missing values and duplicates were identified and handled. Timestamps and dates were parsed and standardized so that daily and weekly patterns could be computed consistently. Id columns and key metrics were validated so that user-level and aggregate analyses would be reliable.
Exploratory & statistical analysis. Exploratory data analysis (EDA) was used to summarize activity levels, sleep duration, and calorie patterns. Descriptive statistics and visualizations (e.g., distributions, time series, segment comparisons) highlighted how users engage with the product—when they are active, how much they sleep, and how these metrics relate. Where relevant, simple statistical checks were used to support conclusions about segments or trends.
Synthesis & recommendations. Findings were summarized into clear themes (e.g., usage patterns, gaps in tracking, opportunities for features or messaging). Strategic recommendations for product development and marketing were tied directly to the analysis, so that each suggestion was backed by the data and framed for business impact.
Outcome. The case study delivers a well-documented R analysis and a set of prioritized, data-backed recommendations that Bellabeat (or similar wellness brands) can use to improve product and user engagement.
