Learn how to calculate standard deviation in Excel using STDEV.P for population and STDEV.S for sample data ranges easily.

820 views

To calculate standard deviation in Excel, use the =STDEV.P(range) function for the entire population or =STDEV.S(range) for a sample. Simply select the cell where you want the standard deviation to be displayed, type the formula, and replace range with your actual data range (e.g., A1:A10). Press Enter to get the result.

FAQs & Answers

  1. What is the difference between STDEV.P and STDEV.S in Excel? STDEV.P calculates the standard deviation for an entire population, while STDEV.S calculates it for a sample of the population.
  2. How do I apply the standard deviation formula to a specific range in Excel? Enter the formula =STDEV.P(range) or =STDEV.S(range), replacing 'range' with your data cell references, such as A1:A10, then press Enter.
  3. Can I calculate standard deviation for non-numeric data in Excel? No, standard deviation functions only work with numeric data. Non-numeric values are ignored or cause errors.
