Stdev.S: Excel Formulae Explained

Key Takeaway:

  • STDEV.S is a powerful Excel function that calculates the standard deviation of a sample set of data, providing a measure of how spread out the data is.
  • Understanding and using STDEV.S correctly is essential for data analysis and decision making in various fields, such as finance, healthcare, and scientific research.
  • To use STDEV.S in Excel, you need to enter the correct arguments and syntax, such as the range of cells containing the data or named ranges. You can also use customized formulas to ignore blank cells or outliers.

Are you confused about the STDEV.S Excel formulae? Worry not, this article explains it all! Learn how to use STDEV.S to unlock the power of Excel for your data analysis needs.

Understanding STDEV.S

Do you know what STDEV.S in Excel formulae is? To understand it, you need to know its definition and importance, as well as its uses. Here’s an overview to help you get the basics of STDEV.S. Once you have a good grasp of it, you can make smart decisions, see the relevance of your data, and reduce mistakes.

Definition of STDEV.S

STDEV.S is a statistical function in Excel that calculates the standard deviation of a sample set. This metric measures the amount of variation or dispersion within the data set. It offers an estimate of how spread out the data points are from the mean value. The formula considers all values in the sample set as equally important, making it perfect for small to medium-sized data sets.

The STDEV.S function is the go-to choice when dealing with smaller data sets that don’t require high accuracy because it analyzes only a portion of the population, not all units. Excel can perform this calculation automatically, saving time and effort in recording data analysis results. However, this methodology’s downside is its sensitivity to outliers or any extreme values that differ from other observed values.

It’s interesting to note that STDEV.S analyzes samples’ unbiasedness rather than populations. Unlike STDEV.P, which uses sample size – 1 for a denominator, STDEV.S uses sample size as a factor hence describing only samples’ variance.

Don’t underestimate the power of STDEV.S, it’s the backbone of statistical analysis and the best defense against data outliers.

Importance and uses of STDEV.S

Statistical analysis is a crucial component of data interpretation, which is where STDEV.S comes into play. This formula can help you analyze the spread of a set of data, indicating how much variability exists between individual data points in relation to the mean. It can be used in various applications, including finance, research, and quality control.

With STDEV.S, you can calculate the standard deviation for a sample set of data with ease. This allows you to determine how much data falls within one standard deviation from the mean, giving you an idea of how representative your sample is. Additionally, it can help identify outliers or extreme values which may be skewing your results.

It’s important to note that STDEV.S only works for sample sets – if you have access to all possible data points (i.e., population), another formula called STDEV.P should be used instead.

Pro Tip: Always keep in mind that STDEV.S is just one tool in your statistical toolkit. Make sure to pair it with other formulas such as Mean or Median to create a comprehensive analysis of your dataset.

How to use STDEV.S in Excel

STDEV.S in Excel is vital to understanding data spread. Let’s explore this formula’s syntax and arguments. Examples of usage will also be provided.

How to use STDEV.S correctly? Here’s the answer!

Syntax and arguments of STDEV.S

When using STDEV.S in Excel, it is important to understand its syntax and arguments. The formula calculates the standard deviation of a set of numerical values containing at least two numbers.

Below is a sample table demonstrating the Syntax and arguments of STDEV.S calculation:


It is crucial to note that while A2:A5 are placeholder cells, they should be replaced with the range of cells containing the data for which you wish to calculate the standard deviation.

STDEV.S calculates the standard deviation using the “n-1” method, where “n” represents the number of values in a sample. For population data truncated complete use STDEV.P instead.

A true fact is that Edward W. Deming developed a statistical control chart and taught statistical quality control techniques during his lectures in Japan following WWII.

Examples of STDEV.S usage

STDEV.S function in Excel is used to calculate standard deviation based on a sample of data. Here’s how you can use this formula to analyze your spreadsheet data:

Example 1Example 2Example 3

Using STDEV.S, you can determine the spread of values in a set of data samples. This helps in identifying the average value from which most of the data points deviate.

It is important to note that more precise calculations come from using datasets greater than three, as it allows for a better representation of range and variance.

According to, “Excel uses the STDEV.S function to calculate standard deviation based on a sample”

STDEV.S may seem like just another standard deviation formula, but it stands out from the crowd like a bat in a room full of pigeons.

Key differences between STDEV.S and other standard deviation formulas

Understand the key distinctions between STDEV.S and other standard deviation formulas, like STDEV.P and STDEVA? To evaluate, you must understand their individual advantages. Although results may be similar, their approach to data is what differs. Let’s compare STDEV.S to its alternatives. What does STDEV.S offer that STDEV.P and STDEVA do not?


When comparing standard deviation formulas, it is important to contrast the characteristics of STDEV.S and STDEV.P. Take a look at the table below to see the main differences:

DefinitionCalculates standard deviation based on sampleCalculates standard deviation based on population
FormulaUses n-1 in the denominatorUses n in the denominator
ApplicationUsed when data represents a sampleUsed when data represents an entire population

It is worth noting that while STDEV.P may be used for large datasets, STDEV.S should generally be preferred for smaller ones. This is because as n approaches infinity, there is little difference between the two formulas.

Interestingly, while both formulas are built into Excel and widely used today across finance and science industries, prior to MS Excel 2010, only one standard deviation formula was available –STDEV (which corresponds to the current STDEV.S in Excel).

Understanding the distinctions between these variance calculations may seem trivial in small numbers but can have huge impacts with significant implications beyond just statistical variance or even business metrics.

Why settle for STDEVA when you can have STDEV.S and actually make sense of your data?


Comparing STDEV.S to STDEVA, the former excludes empty cells, while the latter considers them as zeros. Here’s a table showcasing more differences:

FormulaExcludes Empty Cells?Considers Text as Numbers?

In addition to these two formulas, there are other standard deviation formulas in Excel. However, they all differ in their own unique way, like how some only work for samples and others for populations.

To ensure accurate calculations, it’s important to select the right formula based on your needs. It’s also helpful to double-check your data and make sure it’s formatted correctly before using any formula.

Master the art of STDEV.S and you’ll never have to worry about statistics being standardly boring again.

Efficient ways to calculate STDEV.S

One of the main concerns while working with Excel formulae is finding efficient ways to calculate STDEV.S. Here’s a guide to help you out:

  1. Ensure that your data is well-organized in a column or row
  2. Select an empty cell where you want to display STDEV.S
  3. Use the formula =STDEV.S(range) in the selected cell where ‘range’ refers to the range of cells that contain data
  4. Alternatively, use AutoSum and select STDEV.S as the function by highlighting the range of cells containing data
  5. You can also use Sigma XL software which provides easy-to-use statistical tools for Excel users.
  6. Finally, remember that smaller samples tend to lead to higher standard errors, so use STDEV.S only when dealing with large sample sets.

Additionally, remember that while calculating standard deviation, each observation must be equally weighted. Unequal weightage will result in biased estimates.
