When using STDEVP, common questions usually involve formula entry, argument ranges, unexpected results, and choosing the right standard deviation function; this FAQ includes 4 common questions and 4 glossary terms.
FAQ
What should I do if the STDEVP function shows an error?
- Check whether the function name is spelled
STDEVP. - Make sure the formula starts with
=and that the parentheses are matched. - Check whether the argument separators are correct.
- Correct the formula and press Enter again.
What is the difference between STDEVP and STDEV?
- STDEVP is used for standard deviation based on an entire population.
- STDEV is more suitable for standard deviation based on a sample.
- Confirm whether your data is a population or a sample before choosing the function.
Why does the result look incorrect?
- Check whether the referenced range includes the wrong cells.
- Check whether the data includes text, blanks, or unusual values.
- If you use cross-sheet references, confirm that the referenced range has not changed.
- Review the data and calculate again.
How can I calculate population standard deviation faster in WPS Spreadsheets?
- Organize the data into a continuous range first to reduce selection mistakes.
- Type
=STDEVP(data_range)directly in the result cell. - Reuse the same formula structure with copy or fill.
