Data Analyst roadmap

Turn raw data into decisions with spreadsheets, statistics, SQL, Python and pandas, visualization, BI and storytelling.

What you will learn

  1. 1. Spreadsheets for Analysis

    Formulas and references, lookups, data validation and cleaning, pivot tables and charts in Excel and Google Sheets.

  2. 2. Statistics Foundations

    Summarize data with descriptive statistics, reason with probability and distributions, and spot sampling bias.

  3. 3. SQL Foundations

    Query relational data with SELECT, filtering, sorting and joins.

  4. 4. Python Core

    Pythonic syntax and collections, functions and decorators, iterators and generators, classes and exceptions.

  5. 5. Statistical Inference & Experiments

    Draw conclusions from samples with hypothesis tests and confidence intervals, tell correlation from causation, run A/B tests and fit simple regressions.

  6. 6. SQL for Analytics

    Summarize data with GROUP BY and HAVING, and answer harder questions with subqueries, CTEs and window functions.

  7. 7. Data Analysis with NumPy & pandas

    Load, clean, join and aggregate tabular data with NumPy and pandas.

  8. 8. Data Visualization

    Pick the right chart for the question, plot it with Matplotlib and Seaborn, and combine charts into clear dashboards.

  9. 9. BI Modeling & Tools

    Model data for BI and learn the core concepts shared by Power BI, Tableau and Looker.

  10. 10. Business Questions & Storytelling

    Turn business questions into KPIs and metrics, and present findings as a story that drives decisions.

  11. 11. Data Analyst Capstone

    A scenario-based final challenge mixing spreadsheets, statistics, SQL, pandas, visualization and business storytelling.

Each step unlocks when you answer its questions well enough, and a module you finish counts in every roadmap that shares it.
