Read the distribution, then tell the story. Week 4 computed the numbers and Week 5 read the charts honestly. Week 6 names the shape of the data, chooses the honest summary, and turns the read into a story a decision-maker can act on.
No new homework this week. The runway is clear so you can finish Project 1, due Monday, June 22, 11:59 PM Mountain. Everything below is reference and practice that feeds directly into that deck.
Self-paced deck. Each slide carries an in-deck AI tutor and a self-check. The four questions to ask any dataset, the five distribution shapes and what each one implies, mean versus median done honestly, the empirical rule, and how to turn a finding into an executive story.
The five shapes at a glance: normal, right-skewed, long-tailed, bimodal, and Pareto, with a real Pareto chart, the 80-of-the-80 idea, and a box-and-whisker explainer. What each shape means for a business decision and how to tell them apart on sight.
Reusable prompts that drive analysis, grouped by what you are trying to do: explore, characterize, hunt anomalies, stress-test a claim, and communicate the result. Includes prompts for pasting a chart screenshot into an AI and asking it to describe what it sees.
Drag a skew slider and inject outliers, then watch the histogram, the mean, the median, and a live box-and-whisker plot move together. See for yourself why the mean is the fragile one and when bimodal data is telling you to segment.
Pick an analysis goal, send a prompt to the class AI, and get a response back, including a "chart it" goal that returns a chart you can compare against a reference. The fastest way to feel how prompt wording changes the answer.
The class AI is built into every page here. Open the Ask AI panel on the lecture or any interactive. It now includes a new, faster paid model (Google's Gemini), alongside the on-device option and a copy-paste fallback. Try it while you work and tell me how it goes.
No live session this week. The pre-recorded webinar walks through rendering and presenting your analysis for the Project 1 deck.
Project 1 is the deliverable
Due Monday, June 22. The distribution-reading and storytelling craft from this week is exactly what turns your Excel analysis into a deck an executive can act on.
