Self-checkThe page checks answers in your browser. If you sign in, only the score and pass status are saved to your learner account. The result is not a certificate or formal credential.

1. What must be clear before asking a tool about a table?Whether it has the real data, sample rows, or only a description.Whether the table is sorted correctly.How many rows and columns the table has.Which spreadsheet program produced it.

2. Why define what each column means?Definitions make the prompt shorter.Tools cannot read column headings reliably.It is needed to sort the table correctly.Column meaning controls what any interpretation can honestly say.

3. What is a suggested pattern in the data?A summary of what the table shows.A recommendation about what to do next.A hypothesis you still have to check by calculating it.A finding, provided the tool had the data.

4. Why test an AI-suggested formula before using it?The tool may have used the wrong column names.It may be correct in general and wrong for how your columns are defined.Formulas often contain syntax errors.Different spreadsheet programs need different syntax.

5. What should a chart explanation avoid?Claiming a cause the chart cannot show.Mentioning the units on the axes.Describing the direction of the trend.Naming the time period covered.

6. You describe a table without supplying rows, and the tool returns a total. What is that total?An estimate based on the column names.A placeholder the tool expects you to replace.Correct, if the description was accurate.Invented, however reasonable it looks.

7. What is the quickest way to check a suggested formula?Run it on the full dataset and see if the result looks sensible.Check the syntax against the program's documentation.Give it four rows you can compute by hand and compare.Ask the tool to explain the formula again.

8. Why state the row count in a table analysis?Most report templates require it.Ten rows and ten thousand rows support very different sentences.It shows the analysis was thorough.Readers need it to reproduce the work.

9. Two people define the column "status" differently. What is the consequence?Every figure derived from it can be right for one of them and wrong for the other.The table cannot be sorted consistently.The tool will pick one definition at random.Only the totals are affected.

10. What makes an analysis boundary worth writing down?It shortens the review step.It shows which tool was used.It is required before sharing a spreadsheet.It stops the analysis being quoted beyond what it covers.
