When using DSTDEV, the most common questions focus on errors, unexpected results, and batch use; this FAQ includes 3 common questions and a short glossary.
FAQ
What should I do if DSTDEV returns an error value?
- Check whether all required parameters are complete, especially the database range, field, and criteria range.
- Make sure the data column used in the calculation contains numeric values instead of text or values with extra spaces.
- Open the function arguments dialog box again and review each reference before confirming.
Why does the DSTDEV result look different from what I expected?
- Check whether the field names and criteria in the criteria range match the database headers.
- Confirm that the reference range does not miss target records or include unrelated data.
- Test the formula on a small sample area first, then apply it to the full data range.
How can I use DSTDEV in multiple cells?
- Enter and confirm the DSTDEV formula in the first target cell.
- Select that cell and move the pointer to the fill handle in the lower-right corner.
- Drag to fill down or across, or use copy and paste to apply the formula to multiple cells.
- After filling, check whether relative references should be changed to absolute references.
