+<h1>Google PlayStore Analysis and Rating Predictor</h1>
+
+**GOAL**
+
+To analyze the 'Google Playstore Dataset' Dataset using Exploratory Data analysis and make a regression model to predict the rating of the apps.
+
+**DATASET**
+
+https://www.kaggle.com/datasets/madhav000/playstore-analysis
+
+**DESCRIPTION**
+
+The problem is to identify the apps that are going to be good for Google to promote. App ratings, which are provided by the customers, is always a great indicator of the goodness of the app. The problem reduces to: predict which apps will have high ratings.
+
+The dataset contains the following columns:
+- App : Applicaton Name
+- Category: Category to which the app belongs
+- Rating: Overall user rating of the app
+- Reviews: Number of user reviews for the app
+- Size: Size of the app
+- Installs: Number of user downloads/installs for the app
+- Type: Paid or Free
+- Price: Price of the app
+- Content Rating: Age group the app is targeted at - Children / Mature 21+ / Adult
+- Genres: An app can belong to multiple genres (apart from its main category). For example, a musical family game will belong to Music, Game, Family genres.
+- Last Updated: Date when the app was last updated on Play Store
+- Current Ver: Current version of the app available on Play Store
+- Android Ver: Minimum required Android version
+
+**WHAT I HAD DONE**
+
+* Checked for missing values and cleaned the data accordingly
+* Analyzed the data, found insights and visualized them accordingly.
+* Found detailed insights of different columns with one another using plotting libraries.
+* Deployed four regression models viz., Linear Regression, Support Vector regression, Decision Tree Regression, Random FOrest Regression to predict the rating.
+* Used RMSE(Root Mean Square Error) to evaluate the performance of the models.
+
+
+**LIBRARIES NEEDED**
+
+1. Pandas
+2. Matplotlib
+3. Seaborn
+4. Plotly
+5. Numpy
+6. WordCloud
+7. Sklearn

+**Model Performances**
+
+|Model                      | RMSE               |
+| ------------------------- | -------------------|
+|Linear Regression          | 0.5474395094809866 |
+|Support Vector Regression  | 0.545564956206932  |
+|Decision Tree Regression   | 0.7552190124670595 |
+|Random Forest Regression   | 0.7552190124670595 |
+
+- reviews, type, installs and size columns were used to make the regression model with the rating column being the target vector
+- high RMSE shows that the data has a wide variation in it.
+
+**CONCLUSION**
+- Various Categories of apps have varied ratings
+- Most installed apps belonged to the category of 'Game'
+- Most of the apps on the playstore are rated for all age groups of audience
+- More than 3/4th of the apps are free to install.
+- Among the paid apps, finance apps were most expensive having an average price of $8, followed by Lifestyle apps at $6 and medical apps at $3 average.
+- All the apps were less than 100 mb.
+- Most of the available apps had 'Family' category.
+- The Support Vector regression(with rbf kernel) had the minimum RMSE among the algorithms used making it the best model.
