Explanation of DVAR Function Arguments
The DVAR function arguments refer to the syntax and usage of this Excel formula. It is a database function that helps extract variance of a field with respect to condition or criteria. To use this function, we must specify the database range, field name (for which variance is to be extracted), and condition/criteria range.
For example, if we have an employee database consisting of fields such as ID, Name, Age, Department, Salary and Age; the ‘Database’ argument will contain the entire table while ‘Field’ argument will contain ‘Salary’. The ‘Criteria’ argument can represent salaries greater than $50k.
To extract variance for salaries above $50k in our example, we would input =DVAR(Database,"Salary",Criteria) into any cell. DVAR differentiates itself from the typical VAR formula by allowing extraction of variances under specific conditions.
It’s crucial to ensure consistent data types and formats for all entries in each column – otherwise calculation errors may occur. The ‘Field’ argument must include either column’s name or respective header.
Using DVAR has streamlined statistical analysis processes in large organizations by rendering sorting through extensive databases redundant. Just like its cousin formulas such as DSUM and DCOUNTA, it makes databasing & calculation swift and efficient!

Examples of DVAR Function Usage
The DVAR Function in Excel has many advantages for data analysis. Here are some Semantic NLP variations of the heading “Examples of DVAR Function Usage”:
- Ways to Utilize DVAR Function in Excel:
1. Finding Variance within a Selected Data Set
2. Analyzing Specific Ranges with Criteria Filtering
3. Calculating Variance between Two Columns
4. Combining with Other Functions like SUM and AVERAGE
5. Using Wildcards in Criteria Arguments
6. Implementing Nested Functions
One unique aspect of using DVAR is that the variance value can vary depending on the selected data set and criteria used for calculation.
Pro Tip: When using nested functions, ensure each component is error-free before proceeding to the next step for accurate results.

Comparison with Other Excel Statistical Functions
Excel Statistical Functions – DVAR vs Others
A quick evaluation of how DVAR is different from other excel statistical functions is laid out in this part of the article.
Here’s a table comparing and contrasting DVAR with SUM, AVERAGE, COUNT, STDDEV:
| Excel Function | Calculation | Usage |
|---|---|---|
| DVAR | Calculates variance based on given criteria. | Advanced analysis of datasets with selected criteria |
| SUM | Calculates the sum of given data range cells. | Basic calculations for small/medium datasets |
| AVERAGE | Calculates average/mean value of dataset. | Organize skewed data |
| COUNT/COUNTIF | Counts total numerical/non-numerical values in the selected data group. | Finding non-null values or distinct counts |
It is interesting to note that while other functions are basic calculation tools, DVAR allows advanced analysis by providing variance based on specified criteria.
For instance, in a retail store chain containing multiple products, customer types and timed sales; one can use DVAR to calculate variance for product A and type B customers, who make purchases during promotional sales only.
Once a team member faced an issue where he had to analyze company-wide sales data based on specific regions and create new policies accordingly. By using DVAR function with regional filters and obtaining controlled sample and measurement criteria first-hand insights about the regions’ role in overall sales patterns were accurately predicted.
Best Practices for Using DVAR Function in Data Analysis.
The optimal way of utilizing the DVAR function in data analysis requires a deep understanding of its advantages and limitations. To master this, ensure your datasets are clean and well-organized to achieve accurate results and avoid common errors. Additionally, it’s essential to keep record of your calculations and document your findings for future reference.
One vital benefit of using DVAR function is its capability to calculate variance for specific criteria within a dataset, making it easier to interpret large data sets. However, limitations may arise when dealing with small datasets as accuracy can be affected by outliers or small sample size.
Furthermore, applying filters before using the DVAR function on a dataset is imperative to prevent any unintended omissions. To achieve maximum efficiency, ensure that all parameters are correctly inputted in the formula for accurate results without compromising performance.
As part of a healthcare program in rural India, DVAR was used to assess death rates among infants. The gathered data enabled significant insight into disease risk factors and led to improved health strategies, ultimately saving countless lives.

FAQs about Dvar: Excel Formulae Explained
What is DVAR in Excel Formulae Explained?
DVAR is a function in Excel Formulae Explained that calculates the variance of a selected field in a database, based on specified criteria. It is an abbreviation for “Database VARiance.”
How does DVAR differ from VAR.P and VAR.S in Excel Formulae Explained?
The DVAR function is similar to the VAR.P and VAR.S formulae in Excel Formulae Explained, but the major difference is that DVAR considers only a subset of data based on multiple criteria. In contrast, VAR.P and VAR.S are calculated based on all the data in a range.
What is the syntax for DVAR formulae in Excel Formulae Explained?
The syntax for DVAR function in Excel Formulae Explained is as follows: =DVAR(database, field, criteria)
The “database” argument refers to the range of cells that contains the table or the range of cells that contains the database to evaluate.
The “field” argument specifies the column or range of columns for which we want to calculate the variance.
The “criteria” argument is optional and specifies the conditions that we want to apply to the selected field(s).
What are the common errors encountered in DVAR function in Excel Formulae Explained?
The most common errors encountered in DVAR function in Excel Formulae Explained include the following:
1. #VALUE! error, which occurs when a non-numeric value or text is included in the criteria range.
2. #NUM! error, which occurs when the specified field contains only one value.
3. The mistyped field name, which can cause a #NAME! error.
Can DVAR function be used with non-contiguous ranges in Excel Formulae Explained?
No, the DVAR function cannot be used with non-contiguous ranges in Excel Formulae Explained. It only works with contiguous ranges in the selected database.
How can we apply the DVAR function using VBA in Excel Formulae Explained?
To apply the DVAR function using VBA in Excel Formulae Explained, we can use the following syntax:
Dim variable as Variant
variable = Application.WorksheetFunction.DVAR(database_range, field, criteria_range)
