Summary of Data Quality Assessment:
The dataset has been thoroughly examined and cleaned - it contains 500 customer records with 8 features, had 50 missing values in the payment_method column (10%) which were filled with the most common value "Credit", no duplicates or invalid data, and is now ready for analysis with a notably high churn rate of 86.20%.
Key Insights from the Churn Distribution Analysis:
Overall Churn Crisis: 86.2% churn rate (431 customers) vs only 13.8% retention (69 customers) - this is an extremely high churn rate indicating a critical business problem.
Tenure is a Strong Differentiator: Retained customers have significantly longer tenure (median 26 months) compared to churned customers (median 17 months), showing that newer customers are much more likely to leave.
Higher Charges Drive Churn: Churned customers pay higher monthly charges (median $64.13) compared to retained customers (median $38.87), suggesting price sensitivity is a major churn driver.
Usage Patterns are Similar: Total usage GB is nearly identical between churned and retained customers (both around 275-280 GB median), so usage alone doesn't predict churn.
Support Calls Indicate Dissatisfaction: Churned customers make significantly more support calls (median 2 calls) compared to retained customers (median 0 calls), suggesting support issues correlate with churn.
Monthly Contracts are Highest Risk: Monthly contracts have the highest churn rate at 90.6%, followed by Two-Year (84.8%) and Annual (80.7%), indicating contract flexibility increases churn risk.
Payment Method Shows Minor Variation: Bank Transfer has slightly higher churn (89.6%) compared to Credit (84.9%) and Debit (84.8%), but differences are relatively small.
Customer Base Composition: Most customers are on Monthly contracts (233), followed by Annual (155) and Two-Year (112), with Credit being the most common payment method (205).
