About this project


Welcome to the Bellabeat data analysis case study! In this case study,I am performing many real-world tasks as a junior data analyst. I am assuming that I am working for Bellabeat, a high-tech manufacturer of health-focused products for women, and meet different characters and team members. In order to answer the key business questions.

I will follow the steps of the data analysis process: ask, prepare, process, analyze, share, and act.


These questions will guide our analysis:

  1. What are some trends in smart device usage?
  2. How could these trends apply to Bellabeat customers?
  3. How could these trends help influence Bellabeat marketing strategy?

Business Task:-

Bellabeat is a small company that creates health-focused smart devices for women. Bellabeat’s executive and marketing teams want insight into how consumers use their smart devices in order to reveal opportunities for growth and to guide the company’s marketing strategy.

Bellabeat products and analyze smart devices usage data in order to gain insight into how people are already using their smart devices. And that insights can be applied to Bellabeat’s products.


The datasets downloaded from here: https://www.kaggle.com/arashnic/fitbit This Kaggle data set contains personal fitness tracker from thirty fitbit users. Thirty eligible Fitbit users consented to the submission of personal tracker data, including minute-level output for physical activity, heart rate, and sleep monitoring. It includes information about daily activity, steps, and heart rate that can be used to explore users’ habits. I am using pyhton to analyze this data.

(940, 15)

  • The data have 940 rows and 15 columns
#count distinct values of Id column


  • The data have 33 unique id
  • Convert the ActivityDate into the right format and check the columns
#convert "ActivityDate" to datetime64 dtype
data["ActivityDate"]= pd.to_datetime(data["ActivityDate"],format="%m/%d/%Y")

#print first 5 row to confirm type of columns

#reindexing function to rearrange columns based on new columns


  • Now the data ready to analyze.
  • Show data to ckeck that it will appear properly for analysis.
  • Check the structure of data and show the data statistics for further analysis.
#print first 5 row using head function to check all changes
#get the new shape of dataframe

  • Now, the data have 940 rows and 19 columns
#get statistics of the data



  • Now we can check the activity of users on the bases of different parameter such as calorie burned in per hour, calorie burned in steps, app uses per day and per month.

  • Looking to the above anlysis and chart: The histogram plot "App uses per day of week" shows that the app more used in weekdays(tuesday to thursday) and less used in weekends(friday to monday). And the app used in the month of april more than may.
  • The scatter plot shows the relation between number of hours uses to burned the calories. As above analysis even uses the number of hour more(15-20 hours) in a day the calories burning not more increase, this values is due to the usase of the app in sedentary mode mostly.
  • The next scatter plot shows the relation between the counts of steps to the calories burn. As plot shows that increasing the number of steps, the burning of calories increased. As we can see, the most users steps are on average 7637 steps and the average of 75% of the user is 10727. And the average of 25% is 3700 around. These data shows the good correlation between counts of steps to the calories burned.
  • The scatter plot "calories burned with distance" shows the relation about the distance and calories burned, as we see the plot is similar to the "calories burned with steps". As we seen icreased the ditance is more burned the calories of user's even average of 25% users is 2.62 km but the calorie burning is higher.
  • The pie chart shows the % of each mode,the sedentary mode have higher percentage(81) from the total users. The very active mode and fairly active mode is 1.7%,1.1%. That is the big differenec between the sedentary mode and active mode.
  • The pie chart "% of activity of Distance" show the light active users distance 61.7% and the active users distance 27.8%.


  1. The mostly users use the app on weekdays and in the weekend they are not use the app. So incraese the uses of app even they does not necessary increase the calories burned.
  2. Offer some fitness tracker devices services so they can use them and analyze thier workout and increase the more features in the devices such as sleeping pattern, heart rate water uses ehich is usefull in daily life.
  3. These analysis and trends can help to Bellabeat marketing team to promote and to do campaigns. Marketing team can promote the uses of app by telling more benefits about the app. Marketing team can do awareness campaign on weekend and tells about that how can be fit in future. Give some rewards on the activity so the can use app frequently.
