📁 Dataset Features The dataset covers multiple customer attributes including: 📅 Tenure 👵 Senior Citizen status 💳 Payment method 🌐 Internet services (Fiber Optic, DSL, No Internet) 🔒 Security add-ons (Tech Support, OnlineSecurity) 📄 Contract type (Month-to-Month, 1-Year, 2-Year) 💰 Monthly & Total charges 🚪 Churn status (Yes / No)
📈 Key Insights at a Glance 🔥 Churn Rate Around 26–30% of customers have churned — a major retention concern. 👵 Senior Citizens Senior citizens show ~40% higher churn compared to non-seniors. 📄 Contract Type Month-to-Month customers churn nearly twice as much as yearly contract customers. 💳 Payment Method Customers paying through Electronic Check have the highest churn (~45%) — indicating dissatisfaction or payment-related friction. 📅 Tenure Customers within their first 1–2 months show the highest churn, suggesting poor onboarding or service dissatisfaction early on. Long-tenure customers (40+ months) rarely churn. 🌐 Service Dependencies Lack of OnlineSecurity and TechSupport is strongly linked to churn. Fiber optic internet customers have slightly higher churn due to higher charges.
📊 Visualizations Included The notebook contains: Bar charts & countplots Stacked percentage bar charts Histograms (tenure distribution by churn) Pie charts Heatmap of correlated variables Service-based churn comparisons Payment method impact charts
📝Business Recommendations Based on insights: Promote long-term contracts to reduce month-to-month churn. Improve the first 30–60 days onboarding to retain new customers. Create senior citizen–friendly support plans. Offer incentives to shift electronic check users to digital payments.
