Semester map

From analytics thinking to data-informed decisions.

Prepare data and study databases before the October 19 midterm, then explore visualization for three weeks and generative AI for two weeks before project work and presentations.

01Frame · Weeks 1–2Analytics questions + decision toolsTurn decisions into answerable questions, evaluate evidence, and use dashboards and analytics tools thoughtfully.→ 02Build · Weeks 3–4R foundations + statisticsWork with objects, vectors, data frames, and functions, then summarize center, spread, and distributions.→ 03Prepare · Weeks 5–8Statistics, transformation + databasesSummarize data, practice dplyr, and use Lecture 6 to understand data types, ETL, relational tables, joins, and modern data infrastructure.→

04Assess + visualize · Weeks 9–11 · Coming soonMidterm + data visualizationTake the midterm on October 19, then build charts for distributions, relationships, and time trends.

05Explore AI · Weeks 12–13 · Coming soonGenerative AI + responsible useStudy capabilities and limits, practice prompting and iteration, and verify outputs while considering disclosure, bias, and privacy.

06Apply + present · Weeks 14–16 · Coming soonProject studio + presentationsCheck the group project’s data and code, refine findings, rehearse, and present the completed analysis.
