As we can see from the above mentioned data, some of the apps are having multiple rows. Let's check out if there data is identical or not
In [21]:
As we can see from the above dataframe, ROBLOX app is having identical rows with difference in number of reviews. It may have happened that for the same app, the data has been scraped in different points of time. So we have kept row of an app with maximum number of reviews, assuming it to be the latest one.
In [22]:
Convertingtype of Reviews column to number
In [23]:
google_playstore_df['Reviews'] = pd.to_numeric(google_playstore_df['Reviews'].str.replace('$',''))
In [24]:
google_playstore_df = google_playstore_df.loc[google_playstore_df.groupby(['App'])['Reviews'].idxmax()]
Setting up the parameters for the plots

plt.rcParams['figure.facecolor'] = '#00000000'

What are the top 20 apps present in the google play store as per their Genres?

In [26]:
top_genres = google_playstore_df.Genres.value_counts().reset_index().rename(columns={'Genres':'Count','index':'Genres'})
In [27]:
genres_installs = google_playstore_df.groupby(['Genres'])[['Installs']].sum()
In [28]:
top_genres_installs = pd.merge(top_genres, genres_installs, on='Genres')
top_20_genres_installs = top_genres_installs.head(20)
In [30]:
plt.ylabel("Number of application")
plt.title("Top 20 Genres")
sns.barplot(top_20_genres_installs.Genres, top_20_genres_installs.Count)
Which are the Genres that are getting installed the most in top 20 Genres?
In [31]:
plt.title("Installs according to Genres")
sns.barplot(top_20_genres_installs.Genres, top_20_genres_installs.Installs)
As we can see from the above two plots: Maxinum number of apps present in google play store comes under Tools, Entertainment and Education Genres but as per the installation and requirement in the market plot, scenario is not the same. Maximum installed apps comes under Communication, Tools and Productivity Genres.

Average rating

In [32]:
genres_ratings_df = google_playstore_df.groupby(['Genres'])[['Rating']].mean()
In [33]:
genres_installs_ratings = pd.merge(top_genres_installs, genres_ratings_df, on='Genres')

Highest and lowest rated Genres

In [34]:
genres_installs_ratings.sort_values('Rating', ascending =False, inplace=True)
In [35]:
highest_rated_genres = genres_installs_ratings.iloc[0:20]
lowest_rated_genres = genres_installs_ratings.iloc[-20:]
lowest_rated_genres = lowest_rated_genres[lowest_rated_genres['Rating'].notnull()]
In [36]:
plt.title("Ratings according to Genres")
sns.barplot(highest_rated_genres.Genres, highest_rated_genres.Rating)

What are the count of applications in each category differentiated by their type?

In [38]:
app_count = google_playstore_df.groupby(['Category','Type'])[['App']].count().reset_index().rename(columns={'App':'Count','index':'App'})
In [61]:
df_app_count = app_count.pivot('Category', 'Type', 'Count').fillna(0).reset_index()
In [69]:
df_app_count.set_index('Category').plot(kind='bar', stacked=True, figsize=(18,9))
plt.xlabel("Category", fontsize=15)
plt.ylabel("Count", fontsize=15)
plt.title("Count of applications in each category differentiated by their type")
It looks like certain app categories have more free apps available for download than others. In our dataset, the majority of apps in Family, Food & Drink and Tools, as well as Social categories were free to install. At the same time Family, Sports, Tools and Medical categories had the biggest number of paid apps available for download.

How many apps were installed according to its type?

In [70]:
google_playstore_df['Gaming Category App'] = google_playstore_df['Category']=='GAME'
In [71]:
categoty_type_installs = google_playstore_df.groupby(['Category','Type'])[['Installs']].sum().reset_index()
In [72]:
categoty_type_installs['log_Installs'] = np.log2(categoty_type_installs['Installs'])
In [73]:
plt.title("Number of installs type wise according to Category")
sns.barplot('Category', 'log_Installs', hue='Type', data=categoty_type_installs);
It can be concludd that the number of free applications installed by the user are high when compared with the paid ones.

Size of the applications present in the datset are in MB and KB. Therefore for ease in data processing, converting entire size column to MB.

In [74]:
# Converting KB to MB 
google_playstore_df['Size'] = google_playstore_df['Size'].apply(lambda x: str(x).replace('Varies with device', 'NaN') if 'Varies with device' in str(x) else x)
google_playstore_df['Size'] = google_playstore_df['Size'].apply(lambda x: str(x).replace('M', '') if 'M' in str(x) else x)
google_playstore_df['Size'] = google_playstore_df['Size'].apply(lambda x: str(x).replace(',', '') if 'M' in str(x) else x)
google_playstore_df['Size'] = google_playstore_df['Size'].apply(lambda x: float(str(x).replace('k', '')) / 1000 if 'k' in str(x) else x)
google_playstore_df['Size'] = google_playstore_df['Size'].apply(lambda x: float(x))

How does size impact on the number of installs of any application?

In [76]:
sns.scatterplot(google_playstore_df['Size'], google_playstore_df['log_installs'], hue=google_playstore_df['Type'])
It is clear from the above mentioned plot that size may impact the number of installations. Bulky applications are less installed by the user.

Histogram of log installs

In [77]:
In [78]:
plt.xlabel("Log of Installs")
plt.title("Distribution of Logrithm of Installs")

Histogram of size

In [79]:
# to remove null values from size column
In [80]:
plt.title("Distribution of Size")
From the above histogram, it can be concluded that maximum number of applications present in the dataset are of small size.
In [81]:
user_reviews_df = pd.read_csv('google-play-store-apps/googleplaystore_user_reviews.csv')

Merging dataframes on apps

In [82]:
merged_df = google_playstore_df.merge(user_reviews_df, on="App")
In the merged dataframe, we have three new columns i.e.. Sentiment, Sentiment Polarity and Sentiment Subjectivity. Sentiment basically determines the attitude or the emotion of the writer, i.e., whether it is positive or negative or neutral. Sentiment Polarity is float which lies in the range of [-1,1] where 1 means positive statement and -1 means a negative statement. Sentiment Subjectivity generally refer to personal opinion, emotion or judgment, which lies in the range of [0,1].

What is the distribution of type of reviews in the dataset?

In [83]:
category_sentiment = merged_df.groupby(['Category','Sentiment']).size().reset_index(name='Sentiment Count')
In [84]:
category_sentiment['log_sentiment_count'] = np.log2(category_sentiment['Sentiment Count'])
In [85]:
plt.title("Number of installs type wise according to Genres")
sns.barplot('Category', 'log_sentiment_count', hue='Sentiment', data=category_sentiment);

Histogram of subjectivity

In [87]:
plt.title("Distribution of Subjectivity")
It can be seen that maximum number of sentiment subjectivity lies between 0.4 to 0.7. From this we can conclude that macimum number of users give reviews to the applications, according to their experience.

Does sentiment_subjectivity proportional to sentiment_polarity?

In [88]:
sentimet_subjectivity_polarity = merged_df.groupby(['Category'])['Sentiment_Polarity','Sentiment_Subjectivity'].mean().reset_index().rename(columns={'Sentiment_Polarity':'Sentiment_polarity_avg','Sentiment_Subjectivity':'sentiment_subjectivity_avg'})

In [90]:
