Problem

I Analyzed a dataset from an fictitious telecom company called Databel and analyze their churn rates.

Analyzing churn doesn’t just mean knowing what the churn rate is:
It’s also about figuring out why customers are churning at the rate they are.
And how to reduce churn.

Solution

After analyzing the data from Databel these are some of the insights from the Data.

1. CA had the highest churn rate of 64.24% because it had the lowest number of customers.

2. The churn rate for databel was 26.86% .

3. The biggest reasons for customer churn were competitor made a better offer and they had better devices.
