A Clear Summary of the Business Task

The primary business task for this Bellabeat case study is to analyze smart device usage data from non-Bellabeat devices called Fitbit Fitness Tracker Data to uncover consumer behavior trends. These insights will serve as a foundation for Bellabeat’s marketing team to:

  1. Identify key trends in smart device usage that are relevant to health and wellness.
  2. Understand how these trends apply to Bellabeat’s target audience, specifically women using health-focused devices.
  3. Develop data-driven marketing strategies for one specific Bellabeat product, ensuring alignment with consumer preferences and behavior.

For this case study, I’ve chosen to focus on the Leaf product, applying these insights to guide data-driven marketing strategies that align with consumer preferences. The ultimate goal is to provide actionable recommendations to help Bellabeat grow its presence in the global smart device market.

Summary of All Datasets Used

For this analysis as i mentioned in the business task above, I used a dataset that captures smart device usage data from non-Bellabeat products called Fitbit Fitness Tracker Data. The dataset includes aggregated, fitness tracker data from 03.12.2016-05.12.2016. Thirty eligible Fitbit users consented to the submission of this personal tracker data and its made available by Mobius, a public data-sharing initiative. The data encompasses key health metrics such as:

  • Daily activity: Steps taken, distance covered, and active minutes.
  • Sleep patterns: Hours slept and sleep efficiency.
  • Heart rate data: Resting and active heart rate averages.
  • Caloric activity: Calories burned through exercise and other activities.
  • Weight Log Info, Heart rate and so on 

Data Cleaning and Manipulation

For this case study, I utilized R to clean and manipulate the Fitbit Fitness Tracker Data to prepare it for analysis. Here’s an overview of the steps taken:

1. Merging Tables

Combined daily activity, sleep, and weight data by matching the ActivityDate and Id columns to create a unified dataset for comprehensive analysis.

2. Handling Missing Values

Removed rows with missing values in the TotalSleepRecords, TotalMinutesAsleep, and TotalTimeInBed columns to ensure consistency and accuracy in the analysis.

3. Data Transformation

Created new columns like DayOfWeek and isWeekend to identify usage trends across weekdays and weekends.

Converted weight values from pounds to kilograms and calculated BMI for more meaningful health insights.

Added a SleepEfficiency column to evaluate the quality of users’ sleep by using the formulae (TotalMinutesAsleep /TotalTimeInBed * 100) 

4. Visualization Preparation

Processed the data for creating time-series and scatter plots to explore relationships between various metrics, such as calories burned, weight, and activity levels.

These steps ensured the dataset was cleaned, structured, and ready for effective analysis and visualization.

Key Findings

The first chart highlights insights into the relationship between users’ daily steps and calories burned.

Average daily activity level chart for Bellabeat case study

On average, users burned approximately 7,367 calories daily while taking about 2,304 steps. This noticeable gap suggests that users are engaging in calorie-burning activities that don’t involve many steps, such as strength training, yoga, or other non-step-intensive workouts. Lets check out the Average Daily Sedentary Minutes and Total Distance!

Average sedentary Minutes and Total Distance for Bellabeat case study

The chart above reveals the balance between users daily sedentary time and physical activity. On average, users spend 991 minutes (over 16 hours) in sedentary activities while covering only 5.49 miles daily. This indicates a significant portion of the day is spent in low-movement activities, with relatively limited distance covered. Lets check out the Daily Metrics by Day of the Week!

The chart highlights weekly activity trends, showing Sunday as the most active day with users taking the most steps and covering the longest distances. Despite this, calorie burn remains steady throughout the week, suggesting other factors like metabolism play a role. Sedentary minutes show little variation, pointing to consistent low-movement behavior.

Now lets go even more deeper, lets explore the relationships between Total Steps and Calories Burned

Relationship between Total Steps and Calories Burned for Bellabeat case study

The visualization highlights a clear positive trend: as total steps increase, calories burned also rise, shown by the red regression line indicating a linear correlation. The shaded area around the line reflects the confidence interval, suggesting most data points align with this trend, though some variability exists.

Most users fall within the 5,000 to 15,000 steps range, burning around 2,000 to 3,500 calories. But here’s the interesting thing, there are outliers where individuals burned fewer calories despite high step counts or significantly more calories with fewer steps. These outliers may be influenced by factors like metabolic rate, body composition, or the intensity of activities not captured by step counts.

To further understand the relationship, let’s examine Sedentary Minutes periods of inactivity where steps are not taken and explore whether they also relate to calorie burn. Could it be that even when individuals are sedentary, their bodies still exhibit some energy expenditure? Let’s find out.

Relationship Between Sedentary Minutes and Calories Burned for Bellabeat case study

This visualization reveals a slight negative trend between sedentary minutes and calories burned. The red trendline suggests that as sedentary minutes increase, calorie burn tends to decrease slightly, but the scattered data points indicate a weak correlation.

Notably, there are outliers where individuals burn a significant number of calories despite high sedentary minutes, suggesting that other factors, such as metabolism or brief periods of intense activity, may play a role. Could it be that even during prolonged periods of inactivity, the body still finds ways to expend energy? Wow, lets move forward.

Now, How does the overall daily activity, including sedentary behavior, affect sleep duration?

Lets check the Total Minutes Asleep and Total Steps. Total Minutes Asleep is the time someone spends asleep in a day, while Total Steps shows the cumulative number of steps taken throughout the day, serving as a measure of physical activity. Let’s see if being more steps impacts how much we sleep

Relationship Between Total Steps and Total Minutes Asleep case study

The data shows an intriguing relationship between Total Steps and Total Minutes Asleep. With a correlation of -0.19, there’s a weak negative trend, more steps during the day slightly correlate with less sleep at night. While subtle, the trendline reflects this pattern.

One possible explanation is that individuals who are highly active may also be more restless, which could reduce their total sleep time. However, this raises an important question: does decrease activity increase sleep duration? Lets find out together

Relationship Between Sedentary Minutes and Total Minutes Asleep Bellabeat case study

The calculated correlation between these two variables is -0.601, which suggests a moderate negative relationship. This means that as sedentary minutes increase, total sleep duration tends to decrease. The graph attached clearly illustrates this trend, with a noticeable downward slope. One reason for this trend could be that extended sedentary periods might disrupt the body’s natural energy balance, making it harder to transition into restful sleep. This could stem from reduced physical exertion, which often helps improve sleep quality and duration. It also raises an intriguing question: could prolonged inactivity impact not just how long we sleep but how efficiently we sleep? This sparks curiosity to explore sleep efficiency next, wow!.

Sleep efficiency is the ratio of the actual time spent asleep to the total time spent in bed, expressed as a percentage. It indicates how effectively someone is sleeping during their time in bed. I calculated sleep efficiency using the formula:
TotalMinutesAsleep / TotalTimeInBed * 100.

Relationship Between Total Steps and Sleep Efficiency Bellabeat

The data shows a slight negative trend between Total Steps and Sleep Efficiency. This suggests that as the number of steps increases, sleep efficiency tends to decrease slightly. But the majority of sleep efficiency values remain above 90%, indicating only a minor impact on how efficiently users sleep.

The data reveals no significant relationship between Sedentary Minutes and Sleep Efficiency. Most users maintain a sleep efficiency of around 90%, regardless of their level of inactivity.

Let’s take a closer look at how calories burned relate to weight, with BMI adding some extra color to the story.

BMI Definition: Body Mass Index (BMI) is a simple calculation that helps categorize weight ranges. It’s your weight in kilograms divided by the square of your height in meters, giving insights into whether someone is underweight, healthy, overweight, or obese.

 

Calories Burned vs Weight (Colored by BMI) chart

 

This chart shows how calories burned relate to weight, with BMI adding some context through the colors. We see a general trend where individuals who burn more calories tend to have lower weights, which aligns with our understanding of how energy expenditure influences body weight. However, we also notice an interesting outlier – a data point with a significantly higher weight despite burning fewer calories. This outlier might suggest individual variations or potential confounding factors that are not captured in the current data.

 

BMI and Total Steps Over Time (April - May) chart

Okay, so looking at the chart, it seems like BMI and total steps are both pretty variable over the time period. There’s not a super clear trend in either one, but it looks like there might be some interesting fluctuations. For example, there’s a big spike in steps around the 20th of April, and the BMI seems to go up and down a bit around that time too. This suggests a potential dynamic relationship between physical activity and BMI, though further analysis is needed to establish a definitive link.

 

calories burn and weight over time chart

This chart above shows the relationship between calories burned (red) and weight (blue) over time. While calories burned fluctuated daily, weight remained relatively stable. This suggests that short-term variations in calorie burn don’t significantly impact weight within this timeframe. It’s a reminder that consistent habits matter more than daily changes when it comes to weight management.

 

This brings us to the end of the analysis. The findings revealed patterns in activity, calories, sleep, and weight that offer insights into user behaviors and wellness.

Summary

  1. Average Daily Activity Levels: Users burn an average of 7,367 calories and take 2,304 steps daily, indicating they engage in activities beyond step-based movements.
  2. Average Daily Sedentary Minutes and Total Distance: On average, users spend 991 minutes (over 16 hours) in sedentary activities and cover 5.49 miles.
  3. Daily Metrics by Day of the Week: Sundays show the highest steps and distance, indicating increased outdoor activities or workouts. Calories burned remain consistent throughout the week, suggesting metabolism plays a role. Sedentary minutes are consistent across the week.
  4. Correlation Between Total Steps and Calories Burned: A positive relationship exists, where more steps generally lead to higher calorie burn. However, outliers suggest other factors like metabolism or activity intensity also influence this.
  5. Relationship Between Sedentary Minutes and Calories Burned: A negative trend is observed, where more sedentary minutes lead to slightly lower calorie burn. Outliers indicate that some people burn significant calories despite being sedentary.
  6. Relationship Between Total Steps and Total Minutes Asleep: A weak negative relationship is seen, suggesting that as steps increase, sleep duration slightly decreases.
  7. Relationship Between Sedentary Minutes and Total Minutes Asleep: More sedentary minutes lead to less sleep, with a moderate negative correlation of -0.601.
  8. Relationship Between Total Steps and Sleep Efficiency: A slight negative trend exists, where increased steps slightly reduce sleep efficiency, though most remain above 90%.
  9. Relationship Between Sedentary Minutes and Sleep Efficiency: No significant trend is found, with most individuals maintaining around 90% sleep efficiency regardless of sedentary behavior.
  10. Calories Burned vs Weight (Colored by BMI): There is no strong correlation, although an outlier with a high BMI above 120 kg stands out for further review.
  11. BMI and Total Steps Over Time (April – May): BMI remains stable while Total Steps fluctuates, with no clear correlation between activity and BMI change.
  12. Calories Burned and Weight Over Time: No clear relationship is found, suggesting that factors like diet or metabolism are more influential in weight changes than calorie burn alone.

Conclusion
