HOW IT WORKS
A small exercise. A process you can repeat.
These figures are fictional and do not represent a customer’s results. All amounts are in euros.
YOUR PRACTICE FILE
It all starts with four rows.
The CSV field names stay unchanged so you can follow the exercise and check every sum.

Group sales by region
Choose a bar chart. Drag region to the X axis (grouping), add ventas_eur to the Y axis and select Sum in the aggregation options. In the data table, expect Norte: €450 and Sur: €600; total: €1,050. If they differ, check filters, measure, aggregation and scope.

TRY A SPECIFIC QUESTION
A good prompt makes review easier.
Adapt this example to your file and the result you need.
Prepare a short report in English using this fictional example. January 2026: Norte €300 and Sur €400. February: Norte €150 and Sur €200. Total: €1,050. Describe the distribution by region and month. Show the sums and separate observations from hypotheses. Do not invent causes, customers or forecasts. State that four rows and two months do not establish a stable trend.
