Data Analysis
The first thing we analyzed was the app size (MB) distribution. Our objective was to understand the app size density installed in the App Store and their ranges. We observed that most applications are between 50 and 100 MB. The below image illustrates this:
Next, we tried to correlate between category and app size. We found that the games were the heaviest apps installed in the app store.
During the scraping process, the rating feature was the most prominent metric. We then performed a wide range of exploratory data analyses based on rating and comparing them with other components associated with each app.
The above image depicts that the gaming category has the highest rating category on the app store.
Lastly, we looked into the most-rated new apps and found that Twitter and Reddit lead the top 10.
