The sixth level is the final one: about honesty in conclusions. Correlation and cause, A/B tests, how much to trust a number, a forecast as a corridor, choosing a tool, telling a story with data, and a first project from start to finish. Seven lessons — and you run the full cycle: from a question to a decision you can defend.
Every lesson is a template with demo data: ten minutes to complete, one skill that stays. Open it in the Templates section of Analytics Agent and press “Use this template” to take the lesson on your own data.
Connection Is Not Cause
Shows: two lines moving together are a hint, not a verdict: ice cream sales and drownings run at plus 0.95 because summer drives both; splitting the window kills the false link; a three-question checklist: a third variable? a mechanism? an experiment?
You get: you stop “managing” on coincidences and check what actually stands behind a link.
A/B Test: Checking a Guess Honestly
Shows: random assignment makes the groups comparable; the result is a range, not a verdict: “plus 5.7 points, plus-minus 3”; no peeking early — an early test lies confidently, and the truth arrives by day fifteen; too few visitors means “there is no answer”.
You get: you change buttons, prices, and texts based on an honest test, not on morning luck.
How Much to Trust a Number
Shows: the full number is “4.2% plus-minus 0.9”; the zigzag inside the band is noise, only parting bands are news; fewer observations — a wider band; four times more data buys only twice the confidence.
You get: you stop jumping at random swings and see real shifts — in sales, ads, on the site.
A Forecast Is a Corridor, Not a Promise
Shows: an honest simple forecast = trend + season, plus-minus the width of its own past misses; plan by the edges of the corridor, not the middle; the naive “same month last year” runs first, before you trust a fancier method.
You get: stock, staff, and cash are planned by an honest range with measured accuracy, not by one “exact” number.
From Spreadsheet to Panel: Choosing a Tool
Shows: a ladder of four steps — a spreadsheet, a light panel built in one evening, a company platform, open source on your own servers; five questions in order pick the step; before agreeing, you pilot one real report.
You get: you set up exactly the tool your size needs — without overpaying for the extra.
Telling the Story with Data
Shows: five acts: question, context, proof, conclusion, action; headings are the lesson: a full sentence with a conclusion, not a label; one screen — one thought; the form fits the audience; the heading is written first.
You get: your reports start to convince: the manager gets a verdict, the analyst gets the backup, and the decision comes faster.
Your First Report from Start to Finish
Shows: the whole course on one page: ask → collect → clean → break down → show → say; 86 rows are enough for the full cycle with a check log; every earlier lesson is a station on this line; three ready topics for your own first report.
You get: you run the full cycle with your own hands on your own topic — from one question to three verifiable recommendations and one action.
