## What Is VAR.S Excel Function?

The

VAR.SExcelfunction is an inbuiltStatisticalfunction. It determines the variance based on the given sample of an entire population while ignoring the text and logical values in the sample data.Users can use the

VAR.SExcelfunction to estimate the amount of risk associated with an investment. Also, the function helps confirm if the investment will be profitable based on a sample of the entire data.

For example, the following image shows a sample of an entire dataset containing a list of students and their Mathematics project scores out of 20.

The task is to determine the sample variance based on the given sample data and display the output in cell B13.

Then, considering the above-explained **VAR.S Excel meaning**, we can apply the **VAR.S **Excel** **function in the target cell to achieve the required output.

In the above **VAR.S **Excel** **function example, the **VAR.S()** accepts the range B2:B11 containing the sample data points.

So, the function determines the sample variance based on the input as **11.73333333**, which indicates the amount of dispersion of the sample data around its mean value.

### Key Takeaways

- The
**VAR.S**Excel function determines the sample variance based on the given sample of an entire population. - Users can use the Excel
**VAR.S**function in the accounting and budgeting processes. Also, the function is useful for evaluating the market stability and better forecasting to run the business operations with improved efficiency. - The Excel
**VAR.S**function accepts one mandatory argument,**number1**, and 2 to 254 optional arguments,**number2**,**number3**, and so on. - The Excel
**VAR.S**function output will be incorrect if the given dataset is the whole population. In such a case, we must use the**VAR.P**Excel function.

**Syntax**

The **VAR.S Excel formula** syntax is as follows:

Where,

**number1**: The argument representing the first number required to calculate the sample variance corresponding to a population’s sample.**number2,**…: The 2-254 number arguments corresponding to a population’s sample.

While the first argument in the **VAR.S Excel formula** is mandatory, the remaining arguments are optional.

Furthermore, below are a few aspects of the **VAR.S **Excel** **function arguments to follow to avoid errors:

- Excel offers multiple inbuilt functions, one of them being the VAR.P Excel, to determine variance. So, when we are not sure whether to use
**VAR.P or VAR.S Excel**function, check if the given data is a sample of the population. And if it is, then use the**VAR.S**Excel**VAR.P()**, which returns the variance of the entire population. - The
**VAR.S()**will work only when the sample supplied as input to the function contains a minimum of 2 valid elements. - The
**VAR.S Excel command**arguments can be numbers, names, arrays, or references to cells or ranges containing the sample data points. - Typically, the
**VAR.S**Excel - If the supplied argument value is an array or reference, the
**VAR.S Excel command**only counts the numbers in the array or reference. On the other hand, the function ignores blank cells, texts, logical values, and error values in the array or reference. - If the supplied error values or texts cannot translate into numbers, the function output can be an error value.

We can use the **VAR.S **Excel** **function** **in two ways:

**Access the function from the Excel ribbon.****Enter the function into the worksheet manually.**

#### Method #1 – Access The Function From The Excel Ribbon

Choose a target cell for output – The **Formulas** tab – The **More Functions **group down arrow – The **Statistical **function group right arrow – The **VAR.S **Excel** **function.

The **Function Arguments** window will open. Update the arguments in the **Number1**, **Number2**, … fields.

Furthermore, clicking the **Number2** field will show the next field, **Number3**, clicking which will show the subsequent field, and so on to update in the **Function Arguments** window.

Finally, once we update all the required fields, click **OK** in the **Function Arguments** window to view the **VAR.S() **output in the target cell.

#### Method #2 – Enter The Function Into The Worksheet Manually

- Choose a target cell for the output.
- Type
**=VAR.S(**in the cell. [ Alternatively, type**=V**or**=VAR**and double-click the**VAR.S**function from the listed Excel suggestions.] - Enter the arguments, separated by commas and close the brackets.
- Press
**Enter**to execute the**VAR.S**Excel

### Examples

Check out the following examples to understand the **VAR.S Excel meaning **better to use the function effectively.

#### Example #1

The following dataset shows a sample of data containing the heights of different categories of corn plants.

The aim is to determine and display the variance for the given data in cell B14. However, we might be confused about whether to apply the **VAR.P or VAR.S Excel** function in the target cell.

In this example, the given data is a sample of an entire dataset or population, implying that we must use the **VAR.S **Excel** **function.

**Step 1****: **Choose cell B14 and enter the **VAR.S()**.

*=VAR.S(B3:B12,C3:C12,D3:D12)*

**Step 2: **Press **Enter** to execute the **VAR.S **Excel** **function in the target cell and achieve the required variance of the sample data, **39.63678161**.

On the other hand, the following formulas show the different ways to supply the argument values to the **VAR.S()**, returning the same sample variance of **39.63678161**.

*=VAR.S(B3:D12)*

Or

*=VAR.S({77;80;95;96;85;88;79;80;93;91},{80;83;96;95;88;91;82;83;93;94},{78;81;94;93;86;89;80;81;91;92})*

Or

*=VAR.S(77,80,95,96,85,88,79,80,93,91,80,83,96,95,88,91,82,83,93,94,78,81,94,93,86,89,80,81,91,92)*

[Alternatively, choose the target cell and select **Formulas **– **More Functions **– **Statistical **– **VAR.S**.

The **Function Arguments **window will appear, where we enter the three ranges as the **number1**, **number2**, and **number3** argument values in the corresponding fields.

Finally, clicking **OK** executes the **VAR.S **Excel** **function in the target cell, and the function returns the required variance value of **39.63678161 **based on the input data.]

#### Example #2

The following image shows a sample dataset of 20 data points from a population.

The sample variance’s mathematical formula is as follows:

Where,

- s2: Sample Variance
- xi: The i
^{th}data point in the sample. - x: Sample mean
- n: Sample size

We shall determine the sample variance based on the given sample using the mathematical formula and the **VAR.S **Excel** **function. Assume the target cells are J1:J2.

**Step 1: **Choose cell D1, enter the Excel **AVERAGE **function, and press **Enter**.

*=AVERAGE(A2:A21)*

**Step 2****: **Select cell F2, enter the following formula, and press **Enter**.

*=A2-$D$1*

Next, using the Excel fill handle, update the formula in the range F3:F21.

**Step 3****: **Choose cell G2, enter the below formula, and press **Enter**.

*=F2*F2*

Next, using the Excel fill handle, update the formula in the range G3:G21.

**Step 4****: **Select cell J1, enter the sample variance mathematical formula, and press **Enter**.

**=SUM(G2:G21)/(20-1)**

**Step 5****: **Select cell J2, enter the sample variance Excel function, **VAR.S()**, and press **Enter**.

*=VAR.S(A2:A21)*

First, we determine the sample mean in cell D1 using **AVERAGE()**, with the given sample data range as the input. Thus, we obtain the sample mean as **36.75**.

Next, we calculate the difference between each data point in the sample and the sample mean in the range F2:F21. After that, we find the square of the differences in the range G2:G21.

Finally, we add the square of the differences and divide the sum value by the sample size reduced by one in cell J1. The formula helps us obtain the required sample variance of **545.461** using the mathematical expression.

Furthermore, we apply the **VAR.S()**, with the given sample data range as the input, in cell J2 to calculate the required sample variance of **545.461**.

#### Example #3

The following image shows a sample dataset containing a list of employees and their attendance data.

However, the attendance data contains text values and blank cells.

Let us see how the **VAR.S **Excel** **function works when the sample contains blanks and texts. Assume the target cell is B14.

**Step 1****: **Choose cell B14, enter the **VAR.S **Excel** **function, and press **Enter**.

*=VAR.S(“Three Hundred”,330,””,290,310,”Two Hundred”,305,””,299,285)*

The above output shows that when we supply the sample data points directly as values to the **VAR.S()**, the function counts the blanks and text values. It thus leads to the function returning an error value.

So here is how we can overcome the error.

**Step 2****: **Choose cell B14, enter the **VAR.S()**, and press **Enter**.

*=VAR.S(B3:B12)*

When we supply the sample data range reference as the argument value to the **VAR.S()**, the function ignores the blanks and the text values. It returns the required sample variance based on the numbers in the sample.

Furthermore, supplying the sample data points as array elements to the **VAR.S()** makes the function ignore the blanks and the text values. And we achieve the required sample variance.

*=VAR.S({“Three Hundred”;330;””;290;310;”Two Hundred”;305;””;299;285})*

**Important Things To Note**

- Ensure the sample supplied as input to the
**VAR.S**Excel**#DIV/0!**error. - The
**VAR.S**function ignores texts, blanks, and logical values. However, if we supply them directly as argument values to the function, the function output will be the**#VALUE!**error. - If the provided error values or texts to the
**VAR.S()**do not convert into numbers, the function returns the**#VALUE!**error.

### Frequently Asked Questions (FAQs)

**1. What is the difference between VAR.P and VAR.S in Excel?**

The difference between **VAR.P **and **VAR.S **in Excel is that the **VAR.P()** determines an entire population’s variance. On the other hand, the **VAR.S()** returns the variance of a sample of the entire population.

For example, the following dataset lists athletes and their lap times in seconds.

The aim is to determine the deviation of the lap times from the average value based on the dataset considered as the entire population and as a sample of the entire population. Assume the target cells are E1:E2.**Step 1: **Choose cell E1, enter the **VAR.P()**, and press **Enter**.**=VAR.P(B2:B11)**

We use the **VAR.P()** in cell E1 since we consider the given data as the entire population and must determine the population variance.**Step 2: **Choose cell E2, enter the **VAR.S()**, and press **Enter**.**=VAR.S(B2:B11)**

We use the **VAR.S()** in cell E2 since we consider the given data as the sample of the entire population and must determine the sample variance.

**2. What are the common mistakes while using VAR.S Excel?**

The common mistakes while using **VAR.S** Excel are as follows:

• Using the **VAR.S()** to determine a type of variance other than the sample variance.

• Using the **VAR.S()** for a dataset containing only one data point.

**3. Why isn’t the VAR.S working?**

The **VAR.S **isn’t working because of the following reasons:

• The sample contains less than two numeric data points.

• The applied **VAR.S()** has syntax errors, such as invalid cell references or missing parentheses.

• The data points supplied directly as values to the **VAR.S()** include texts, blanks, logical, and error values.

• The supplied error values or texts to the **VAR.S()** do not translate into numbers.
