Python Fundamentals
Build, test, and debug useful Python programs with clear control flow, reusable functions, structured data, files, exceptions, packages, and classes.
3
SQL and Relational Databases
Design a relational schema, write reliable queries, update data safely, use transactions, and diagnose common correctness and performance problems.
4
Statistics for Data Science
Summarize data, reason about probability and sampling, interpret confidence intervals and tests, and communicate statistical uncertainty responsibly.
5
Data Analysis with Python
Clean, explore, summarize, validate, combine, and communicate findings from structured datasets through reproducible Python workflows.
6
Data Visualization
Select, create, evaluate, and communicate clear, accessible visualizations for distributions, comparisons, relationships, time series, and dashboards.
7
Machine Learning Fundamentals
Prepare data, train baseline regression and classification models, evaluate predictions, detect leakage and overfitting, and document limitations.
