🗺️ Complete Data Science Roadmap (2025 Edition)

Here’s your no-fluff roadmap — designed for clarity, depth, and action.

---

📌 1. Learn Python (First Step Always)

Why? Python is the heart of Data Science.

Master:

• Variables, Loops, Functions

• Data Structures (Lists, Tuples, Dicts)

• Libraries: NumPy, Pandas, Matplotlib, Seaborn

🔥 Focus on writing clean code and solving real-world datasets.

---

📌 2. Mathematics & Statistics

Math is the brain of Data Science. You don’t need to be Einstein, but you do need these:

• Linear Algebra (Vectors, Matrices)

• Probability & Stats (Distributions, Hypothesis Testing)

• Calculus (Derivatives, Gradients)

• Set Theory & Logarithms

🎯 We’ve broken these down beautifully in our Cheatsheet Bundle.

---

📌 3. Data Wrangling & Analysis

You’ll work with dirty, unstructured data most of the time.

Learn:

• Cleaning with Pandas

• Manipulating DataFrames

• Handling Missing Values

• Data Aggregation & Grouping

Visualize with:

• Matplotlib, Seaborn, Plotly

---

📌 4. SQL & Databases

Every Data Scientist must know SQL.

Essential SQL Concepts:

• SELECT, JOIN, GROUP BY, HAVING

• Subqueries & CTEs

• Database design logic

• Connecting SQL with Python

Also touch on:

• MongoDB basics (NoSQL)

---

📌 5. Machine Learning

Core ML Algorithms to Master:

• Linear & Logistic Regression

• Decision Trees, Random Forests

• KNN, Naive Bayes, SVM

• Clustering (K-Means)

• Model Evaluation Metrics

👉 Learn Scikit-Learn like a pro.

---

📌 6. Real Projects (Your Career Depends on These)

Real Projects = Real Job Readiness.

Top Project Ideas:

• Predict House Prices

• Sentiment Analysis on Tweets

• Credit Card Fraud Detection

• Netflix-style Recommendation Engine

• COVID-19 Data Analysis Dashboard

🎓 Bonus: These projects are pre-outlined in the Cheatsheet Bundle to help you get started.

---

📌 7. Advanced Concepts (Optional but Valuable)

Explore:

• Deep Learning with TensorFlow / PyTorch

• NLP (Text Processing, Chatbots)

• Big Data Tools: Spark, Hadoop (for enterprise jobs)
