What Is the Difference Between STDEV.S and STDEV in Excel?

Learn the difference between Excel's STDEV.S and STDEV functions and when to use sample vs. population standard deviation.

76 views

STDEV S refers to the sample standard deviation, used when you have a sample of a larger population. STDEV is an older function in Excel that also calculates sample standard deviation. To avoid confusion and ensure compatibility with modern Excel versions, use STDEV.S for sample data and STDEV.P for population data.

FAQs & Answers

  1. What does STDEV.S stand for in Excel? STDEV.S stands for sample standard deviation in Excel and is used when your data represents a sample from a larger population.
  2. Is STDEV the same as STDEV.S in Excel? STDEV is an older Excel function that calculates sample standard deviation, similar to STDEV.S, but STDEV.S is preferred for clarity and compatibility with newer Excel versions.
  3. When should I use STDEV.P instead of STDEV.S? Use STDEV.P when calculating the standard deviation for an entire population, while STDEV.S is used for sample data.
