Data Description
We collect the dataset from IBM Community. This dataset contains five spreadsheets. They contain the information about the demographics, location, population, services and status about customers. Demographic is the information about customers’ gender, age range, and if they have partners and dependents. Location is the information about customers’ detail location such as country, city. Status is the information about customers’ status of churn and the reason about churn. There are 7043 entity instances in the dataset. Each customer is identified by Customer_ID column. There are 42 columns with 40 attributes. Customers who left within the last month is the column named Churn_Value. The churn customers are recorded as 1 and the non-churn customers are recorded as 0.
