Week 4 · Descriptive Analytics and Statistical Interpretation

This week has two hands-on activities, run within the three-hour session. Both practise the same discipline: an agent hands you a clean-looking number, and you decide what it is standing on before you act on it.

1 · Descriptive analytics

Ask an agent three questions about social engagement, verify one answer with a pivot table, and turn each into a sentence a manager could act on. Deliverable: three verified insight sentences + one pivot table (Stage 3 Summary and Verification).

2 · Statistical thinking

Put two agents against each other on three claims from Kopi Kembali’s marketing review, then write your own verdict for each. Deliverable: three claim critiques, one paragraph each (the Statistical Claim Audit).

Before you start

• Work in pairs.
• You will use an agent — Claude or Manus — plus a spreadsheet (Google Sheets or Excel) for the pivot table in Activity 1. This site does not run anything; it gives you the flow, the files, and the prompts.
• Each activity feeds a specific evidence section of your Individual Analytics Portfolio, and each ends with an xSiTe checkpoint. Submit your individual copy, not the living team files.

The one idea for the week

A summary statistic — a mean, a correlation, a percentage lift — is a claim in disguise. Before you repeat it to a decision-maker, ask what it would look like if it were wrong: a skewed distribution, a confounder, an unchecked before-and-after window.
