• What you can do next: You can edit the formula, copy it, or reference the result in other cells.

Tips While Using

• Common mistake: Missing parentheses, missing separators, or mismatched parameter types can cause an error.

3. Use cross-worksheet references or nested calculations

Entry point: Formula bar

1. In the LOGEST parameters, select a data range from the current worksheet or another worksheet.
2. If needed, add other references or nested expressions to build a combined analysis formula.
3. Check whether the referenced range is correct.
4. Press Enter to finish the formula.

Success Criteria

• Interface result: The formula includes worksheet references or combined expressions.
• What you can do next: You can fill, copy, or adjust the reference range.

Tips While Using

• Common mistake: Choosing the wrong worksheet or range in a cross-sheet reference can affect the result.

4. Check updated results after data changes

Entry point: The result cell and its referenced range

1. Edit the data cells referenced by LOGEST.
2. Watch whether the result cell changes at the same time.
3. If needed, review the formula range again.
4. Save the worksheet and continue your analysis.

Success Criteria

• Interface result: The result updates when referenced data changes.
• What you can do next: You can continue analysis or summary work based on the updated result.

Tips While Using
