  • Jupyter Notebook tutorials: This interactive coding environment allows you to run and document code seamlessly.

Understanding these tools helps support a complete roadmap to becoming a data scientist with no experience by building practical capabilities early.

Step 4: Data Preprocessing and Cleaning

Data preprocessing is often overlooked but critical:

  • Data preprocessing steps: Handle missing values, and outliers, encode categorical variables, and normalise features.
  • Data cleaning techniques: Deduplicate data, ensure format consistency, and remove noisy data.
  • Use no-code tools for data science beginners, such as Google AutoML or Dataiku for faster workflow understanding.

Learning these tasks sets a strong foundation for professional work.

Step 5: Data Visualization Skills

  • Learn data visualization tools such as Matplotlib, Seaborn, Tableau, and Power BI.
  • Build dashboards and visual storytelling projects.
  • Use visualizations to derive insights and communicate findings clearly.

The ability to visualize data clearly also supports effective Responsive Design when building web apps or presenting insights interactively.

Step 6: Dive into Machine Learning

  • Supervised and unsupervised learning: Learn linear regression, logistic regression, decision trees, random forests, k-means, PCA.
  • Explore libraries such as Scikit-learn, TensorFlow, and PyTorch.
  • Study evaluation metrics and model validation.

Understanding machine learning basics will help you transition from a data analyst role into more advanced data science responsibilities.

Step 7: Build Real-World Projects

Apply your learning through:

  • Entry-level data science projects include loan prediction, customer segmentation, or movie recommendation.
  • Use a data science roadmap using real-world projects to gain practical experience.
  • Publish your projects using GitHub, Kaggle, or blogs.

This step is critical for those following a roadmap to become a data scientist without coding or formal education.
