STDEVP

The STDEVP function in Google Sheets is a statistical tool used to calculate the standard deviation based on an entire population. It is a measure of the amount of variation or dispersion in a set of values. Learn how to use this function effectively with our comprehensive guide below.

Function Syntax and Parameters

Syntax: STDEVP(value1, value2)

Parameters:

  • value1: The first value or range of values to consider for the standard deviation calculation.
  • value2: [Optional] Additional values or ranges to consider.

Step-by-Step Tutorial

To calculate the standard deviation based on an entire population using the STDEVP function, follow these steps:

  1. Using STDEVP with individual values:

    • Example: =STDEVP(10, 15, 20, 25, 30)
    • Result: The standard deviation based on the entire population of values is returned.

  2. Using STDEVP with a range of cells:

    • Example: If the data is in cells A1:A5, then =STDEVP(A1:A5) will calculate the standard deviation for the entire population.

Use Cases and Scenarios

  1. Quality Control: Calculate the standard deviation of measurements to assess the variation in a production process.
  2. Market Research: Analyze the variability of customer satisfaction ratings.
  3. Finance and Investments: Evaluate the volatility of investment returns over a population of assets.
