The Data Science Bootcamp

A coach that teaches by asking — not by lecturing

The Lighthouse Coach is an AI Socratic coach built on Cognosco Learning's The Data Science Bootcamp course, in the Personal Effectiveness & Well-Being category. It does not play videos at you. It holds a conversation: it asks you a question, listens to your answer, names the misconception it hears, affirms what you got right, and asks the next question — the way a great coach works in the room.

Every organisation runs twice — once in the work itself, and once in the records the work leaves behind. Orders, clicks, tickets, deliveries, payments, complaints: the second running is data, and it is always an imperfect shadow of the first. This course teaches you to work that shadow honestly, end to end — a disciplined workflow, not a catalogue of algorithms and not a course in programming craft.

You learn the front half first. Frame a question so it serves a real decision, in six lines a sponsor can sign; acquire data and audit its provenance, coverage, and definitions before trusting a row; clean and join without quietly changing the story; and explore before you model, so the data can talk back. Then the statistics literacy the rest stands on: distributions, variation, honest intervals, significance traps, and the humble baseline every claim must beat.

Then you earn the verdict. Choose a model family as a workflow decision; split data so validation means something; hunt the leakage that makes good-looking results worthless; score with measures matched to the decision's real costs; tune without fooling yourself; diagnose errors by slice; and close with the disciplines that decide whether good work survives — communicating to decision-makers, documenting for reproducibility, checking for harm, and monitoring after you ship.

It works in two movements. First, Module 1 — The Front Half: From Question to Understanding — work through Concepts 1–9, finishing with The Workflow Audit and Exploration Brief; then, Module 2 — The Back Half: From Model to Decision — work through Concepts 10–18, finishing with The Model You Can Ship — Or Stop.

Both capstones produce real artifacts — The Workflow Audit and Exploration Brief, a complete front-half audit and exploration brief for Tideglass Foods, a fictional meal-kit subscription company, closing in a go / no-go for modelling; and The Model You Can Ship — Or Stop, a validated modelling plan, readout, and ship-or-stop recommendation in which every claim is stated at the strength its evidence supports.

The numbers discipline is part of the course. A result is a claim, not a trophy: every computed figure in the course recomputes exactly from the inputs printed beside it, so you can check any number with a pencil — and learn to say, in plain words, exactly how far each result should be trusted.

The course is self-paced and always on — roughly 30 minutes per concept, about 9 hours in full, taken in as many sittings as you like. You can type your answers, or talk out loud: the Voice Coach speaks its questions and listens to your spoken replies. Learners who already know the material can test out concept by concept.

This is the two hundred and thirteenth course in The Lighthouse Signature Series — the online counterpart to the one-day, in-person learning Cognosco Learning has delivered since 2002.
