INTERACTIVE DATA SCIENCE EXPERIENCE

The Data Scientist:
From Raw Data to Production

Explore the complete lifecycle of a Data Science project. Discover how a Data Scientist transforms raw data into actionable insights, predictive models and real-world business solutions.

07 Project Stages

21+ Technical Tasks

01 Industry Project

Project Overview

Understand the business problem before writing your first line of code.

Industry Use Case

Telecom Customer Churn Prediction

A telecommunications company is experiencing customer attrition. The objective is to identify customers who are likely to discontinue their subscriptions and help the business take preventive action.

02. Understanding the Data

Explore the kind of dataset a Data Scientist works with.

Sample Dataset

Telecom Customer Records

Customer ID	Tenure	Monthly Charges	Contract	Churn
C001	2 Months	₹850	Monthly	Yes
C002	24 Months	₹450	Annual	No
C003	5 Months	₹920	Monthly	Yes
C004	36 Months	₹550	Annual	No
C005	8 Months	₹700	Monthly	Yes

These are illustrative records created for demonstration. They are not actual customer data.

03. Exploratory Data Analysis

Discover patterns, relationships and trends before building a model.

Customer Churn Distribution

Illustrative distribution of 7,043 customers.

Questions to Investigate

Which contract type has the highest churn?
Does customer tenure affect churn?
Are higher monthly charges associated with churn?
Do support complaints predict customer attrition?

04. Machine Learning Model Evaluation

Understand how a classification threshold changes model predictions.

Interactive ML Simulator

Prediction Threshold Simulator

Adjust the probability threshold to determine which customers are classified as high churn risk.

Churn Probability Threshold 50%

10% — More sensitive 90% — More conservative
