📊 What is Data Science?

Data science is the field that combines statistics, computer science, and domain knowledge to extract useful insights and knowledge from data.
It involves the end-to-end process of working with data:

1. Collecting data (from databases, APIs, sensors, logs, etc.)

2. Cleaning and preparing data (handling missing values, inconsistencies)

3. Exploring and analyzing data (finding patterns, trends, correlations)

4. Building models (using machine learning and AI to make predictions)

5. Interpreting results to guide business or scientific decisions

6. Communicating insights through reports, dashboards, or visualizations

👩‍💻 What Does a Data Scientist Do?

A data scientist is a professional who applies data science techniques to solve real-world problems. Their role is a mix of mathematician, programmer, and business problem-solver.

🔑 Key Responsibilities

• Data Collection & Preparation: Gather raw data from different sources and clean it for analysis.

• Exploratory Data Analysis (EDA): Identify trends, patterns, and relationships in data.

• Model Building: Use machine learning and statistical methods to build predictive or classification models.

• Evaluation & Validation: Test models to ensure accuracy and reliability.

• Data Visualization: Create dashboards, charts, and reports to present insights.

• Business Communication: Translate technical findings into clear recommendations for decision-makers.

⚙️ Skills of a Data Scientist

• Technical: Python, R, SQL, machine learning, statistics, data visualization tools (Tableau, Power BI).

• Mathematical: Probability, statistics, linear algebra.

• Business: Understanding the problem domain to apply the right techniques.

• Soft Skills: Communication, critical thinking, storytelling with data.

---

👉 In simple terms:

• Data Science = turning raw data into actionable knowledge.

• Data Scientist = the person who does this by combining math, coding, and business understanding.
