## Excel VARA function

The **VARA function** calculates the variance based on a given sample.

#### VARA function vs. VAR.S function

Both the **VARA function** and **VAR.S function** can be used to estimate the variance based on given sample. The difference between them is that the VARA function evaluates text values and logical values in references, whereas VAR.S function does not include text values and logical values in references as a part of the calculation.

#### Excel variance functions

The following table lists all Excel variance functions and their usage notes, which can help you choose the one that best suits your needs.

Name |
Data type |
Text and logicals in references |

VAR | Sample | Ignored |

VAR.S | Sample | Ignored |

VARA | Sample | Evaluated |

VARP | Population | Ignore |

VAR.P | Population | Ignored |

VARPA | Population | Evaluated |

#### Syntax

**VAR(value1, [value2], ...)**

#### Arguments

**Value1**(required): The first sample value corresponding to the population.**Value2, ...**(required): The second and more sample values corresponding to the population.

#### Remarks

**Tips:**If the data you provided represents the whole population, it is recommended to use the VARPA function.

**Logical values:**TRUE (1) or FALSE (0);

**Text representations**of numbers: Numbers enclosed in double quotation marks such as “2”.

**Logical values**: TRUE is evaluated as 1, and FALSE is evaluated as 0.

**Text value**: is evaluated as 0.

**#VALUE!**error occurs if any of the supplied arguments you typed directly in the function are text strings that cannot be interpreted as numbers by Excel.

**#DIV/0!**error occurs if there are less than 2 numeric values supplied to the function.

#### Return value

It returns a numeric value.

#### Example

The following table is a sample of scores. To estimate the variance based on it, while needing to evaluate the logical value and text value in the referenced cells, you can apply the VARA function to handle it.

Select a cell (says F6 in this case), enter the formula below and press the **Enter** key to get the variance.

**=VARA(C6:C13)**

**Notes:**

1. The argument in the formula above is supplied as a cell range.

**=VARA(C6,C7,C8,C9,C10,C11,C12,C13)**

**=VARA(C6,1,C8,C9,0,C11,C12,C13)**

2. In this case, if you apply the VAR.S function to estimate the variance based on a given sample in C6:C13, the logical value and the text in the reference will be ignored. See the following screenshot:
