Case Study scenario as below:

In developed countries, telecommunications has become one of the most important industries. The level of competition has increased as a result of technological advancements and an increase in the number of operators. Companies are relying on a variety of techniques to thrive in this competitive industry. To enhance revenue, three key tactics have been proposed: (1) attract new consumers, (2) upsell existing customers, and (3) extend client retention periods. However, when comparing these strategies based on the value of their return on investment (RoI), it was discovered that the third strategy is the most profitable, demonstrating that retaining an existing customer is much less expensive than acquiring a new one, as well as being much easier than the upselling strategy. To implement the third method, businesses must reduce the risk of customer churn, sometimes known as "moving from one provider to another."

In order to reduce the risk of customer churn, you would like to first generate valuable information in helping you to give insights on the important variables affecting customer churn through exploratory data analysis
