STDEV

The STDEV function in Google Sheets is a statistical tool used to calculate the standard deviation based on a sample. It measures the amount of variation or dispersion in a set of values. Learn how to use this function effectively with our comprehensive guide.

Function Syntax and Parameters

Syntax: STDEV(value1, [value2, ...])

Parameters:

  • value1: The first value or range for which you want to calculate the standard deviation.
  • value2, ...: [Optional] Additional values or ranges for which you want to calculate the standard deviation.

Step-by-Step Tutorial

  1. Using STDEV with individual values:

    • Example: =STDEV(2, 4, 6, 8, 10)
    • Result: 3.1622776601683795

  2. Using STDEV with a range of cells:

    • Example: If cells A1 to A5 contain the values 5, 7, 9, 11, 13, then =STDEV(A1:A5) will return 3.1622776601683795.

Use Cases and Scenarios

  1. Quality Control: Calculate the standard deviation of measurements to analyze the consistency of product quality.
  2. Investment Analysis: Determine the volatility of returns by calculating the standard deviation of a portfolio.
  3. Survey Analysis: Measure the level of agreement or disagreement among survey responses.
