Telco Customer Churn Analysis: EDA & Classification Models

Andrew Cole

Please refer to the links below for a detailed blog post walking through the analysis:

Project Overview

In the commercial world, customers are king. Understanding the customer is of the utmost importance and understanding their behavior patterns can lead to very impactful business decisions. Customer Churn is the rate at which a commercial customer leaves the commercial business/platform and takes their money elsewhere, and understanding the underlying customer patterns will greatly impact a business' ability to retain their customers. As a data researcher trying to break into the professional world, I thought it would be pertinent to get a better understanding of what these churn data features may look like and how they can be used to understand the customer.

In this repository I will utilize a telecommunication company's (Telco) customer dataset to perform a very detailed Exploratory Data Analysis to develop a strong understanding of any patterns or trends existing in our data. Secondly, I will process the data and build a series of binary outcome classification models that will try to effectively predict whether a customer will or will not churn from the telecommunications platform.

The Data

The data is sourced from Kaggle (https://www.kaggle.com/blastchar/telco-customer-churn). Our dataset contains 7043 entries representing 7043 unique customers. There are 21 columns, with 19 features (target feature = 'Churn'). The features are numeric and categorical in nature, so we will need to address these differences before modeling.

Included in this Repository

  • EDA.ipynb : Commented Walkthrough of the Exploratory Data Analysis process
  • eda_module.py: Module with functions for execution of EDA process
  • regression.ipynb: Commented walkthrough of Logistic Regression
  • regression_module.py: Module with functions for execution of Logistic regression
  • KNN.ipynb: K-Nearest Neighbors Classification Model
  • Telco Customer Churn Analysis.pdf: Google slides presentation (as if an insight presentation was required per deliverables)
  • data [folder]: Folder containing all used data
  • pics [folder]: Folder containing figures & screenshots for medium blog posts
