1 What is the main purpose of our study (Data Science Programming)?

The main purpose of studying Data Science Programming is to extract meaningful insights from data using programming, statistics, and analytical thinking.

As Data Science students, we aim to:

• Collect and clean data
• Analyze and visualize data
• Build predictive models
• Support decision-making using data

In short, the goal is to transform raw data into useful information that can solve real-world problems.

2 Why do we learn about it?

We learn Data Science Programming because today’s world is driven by data. Almost every industry such as business, healthcare, finance, education, and technology relies on data for decision-making.

By learning it, we can:

• Identify patterns and trends in large datasets
• Make data-driven decisions instead of assumptions
• Solve complex problems using algorithms
• Increase career opportunities in the digital era

This knowledge prepares us to become data analysts, data scientists, machine learning engineers, or business intelligence specialists.

3 What tools do we need to expert about?

As a Data Science student, these are the main tools we need to become experts in:
