Data Science Track

Prepare for Data Scientist roles focused on exploratory analysis, statistical reasoning, predictive modeling, and communicating insight to technical and non-technical stakeholders.

Before you start

This track shares its analytical foundation with the Machine Learning Engineer track, built around exploration, statistics, and modeling. Where that track goes deep on production engineering, this one goes deep on analysis and communicating findings to stakeholders.

Detailed curriculum

› stage/01/explore

Data Handling and Exploratory Analysis

Project: build a clean data ingestion, validation, and EDA pipeline for a messy customer, sales, or operations dataset.

  • Python and data cleaning with pandas and NumPy
  • SQL joins, aggregations, CTEs, and window functions
  • Git workflow and reproducible notebooks
  • Asking sharper questions of a raw dataset before modeling anything

› stage/02/statistics

Statistics and Probability for Analysis

Project: implement linear regression with gradient descent from scratch, then explain the statistical assumptions behind the result.

  • Linear algebra: vectors, matrices, dot product
  • Probability: distributions, conditional probability, Bayes' rule
  • Statistics: mean, standard deviation, correlation, sampling, confidence intervals
  • Reading a model's assumptions instead of trusting its output blindly
Gradient DescentBayesian InferenceMaximum Likelihood EstimationConfidence Intervals
› stage/03/prep

Feature Engineering and Data Preparation

Project: create a reusable preprocessing workflow for a tabular business dataset and document every transformation.

  • Missing-value and outlier handling, duplicate checks
  • Encoding and scaling choices, and when each applies
  • Train/validation/test splits and leakage prevention
  • Documenting transformations so another analyst can reproduce them

› stage/04/predict

Predictive Modeling for Business Questions

Project: predict a business outcome (price, churn, risk, or demand) and explain the result in terms a stakeholder can act on.

  • Regression and classification problem framing
  • Choosing metrics that match the business objective, not just accuracy
  • Residual and error analysis
  • Translating a model's output into a recommendation

› stage/05/segment

Segmentation, Clustering, and Anomaly Detection

Project: build customer segmentation and anomaly detection for transaction, usage, or operational data.

  • Distance metrics and clustering assumptions
  • Cluster validation and profiling
  • Dimensionality reduction for visualization
  • Flagging unusual records worth a second look

› stage/06/communicate

Communicating Insight and Interview Readiness

Project: turn one analysis into a stakeholder-ready report and defend it in a mock review.

  • Explaining metrics and trade-offs to non-technical audiences
  • Writing a clear analysis README and summary
  • Interpreting model drivers with SHAP/LIME-style explanations
  • Answering data science interview questions with real trade-offs

Capstone portfolio projects

Business Insight Report

Take one messy dataset through EDA, statistical analysis, and a predictive model, then package the findings into a stakeholder-ready report with a clear recommendation.

Segmentation and Anomaly Deep Dive

Segment users, products, or transactions and flag unusual records worth investigating, backed by a written business recommendation.
