# OpenOffice Calc Tutorial AVERAGE Function

## What is the AVERAGE Function?

The AVERAGE function is a mathematical function that is commonly used in spreadsheets, including OpenOffice Calc, to calculate the average or arithmetic mean of a set of numbers. It allows you to easily find the central tendency or average value of a range of cells.

By definition, the average of a set of numbers is calculated by adding up all the numbers in the set and dividing the sum by the count of numbers. This provides you with a single value that represents the “typical” or “average” value in the set.

The AVERAGE function in OpenOffice Calc simplifies this calculation by allowing you to specify a range of cells or individual cell references as arguments, and it automatically performs the necessary calculations to derive the average.

This powerful function is extremely useful in a variety of scenarios, such as finding the average test score of a class, calculating the average sales per month, determining the average temperature for a week, and many more.

Using the AVERAGE function can save you time and effort, especially when dealing with large data sets, as it eliminates the need to manually calculate the average using a calculator or writing complex mathematical formulas.

Furthermore, it provides you with the flexibility to include or exclude specific cells in the calculation, such as ignoring empty cells or considering only positive or negative numbers. This allows you to customize the average calculation based on your requirements.

## Syntax and Arguments of the AVERAGE Function

The AVERAGE function in OpenOffice Calc follows a specific syntax and accepts different arguments to perform the average calculation. Understanding the syntax and how to use arguments correctly is crucial for using this function effectively.

The basic syntax of the AVERAGE function is as follows:

`=AVERAGE(argument1; argument2; ...)`

The function starts with an equal sign (=) followed by the function name (AVERAGE) and parentheses (). Within the parentheses, you can include one or more arguments separated by semicolons (;).

Now let’s take a closer look at the different arguments you can use with the AVERAGE function:

Range: The most common argument is a range of cells. You can specify a range by using the cell references of the first and last cells, separated by a colon (:). For example, `=AVERAGE(A1:A10)` will calculate the average of cells A1 to A10.

Cell references: Instead of a range, you can also provide individual cell references as arguments. For example, `=AVERAGE(A1, B1, C1)` will calculate the average of cells A1, B1, and C1.

Number values: You can also directly include number values as arguments. For example, `=AVERAGE(5, 8, 12)` will calculate the average of the numbers 5, 8, and 12.

Named ranges: If you have defined named ranges in your spreadsheet, you can use those names as arguments in the AVERAGE function. This makes your formulas more readable and easier to maintain.

It’s important to note that the AVERAGE function automatically ignores any non-numeric values or text in the specified range or arguments. It only considers numeric values in the calculation, making it a convenient tool when dealing with mixed data types.

By understanding the syntax and embracing the available argument options, you can fully leverage the power of the AVERAGE function in OpenOffice Calc and streamline your calculations with ease.

This can be useful when analyzing datasets with mixed values or when focusing on specific subsets of data. The AVERAGE function in Calc allows you to easily achieve this.

Let’s consider an example where you have a range of numbers representing monthly expenses, both positive and negative. To calculate the average of only the positive expenses, follow these steps:

1. Select the cell where you want the average result to appear.
2. Type the AVERAGE function, starting with an equal sign (=).
3. Specify the range of cells containing the monthly expenses data.
4. Append the function with the condition to include only positive numbers using the IF function.
5. Press Enter to complete the formula.

For instance, let’s assume the monthly expenses are in cells A1 to A12, with positive expenses represented by positive values and negative expenses represented by negative values. To calculate the average of only the positive expenses, you would enter the following formula:
`=AVERAGE(IF(A1:A12 > 0, A1:A12))`

Remember to enter this formula as an array formula by pressing Ctrl+Shift+Enter. Calc will then calculate and display the average of the positive expenses in the selected cell.

Similarly, if you want to calculate the average of only the negative expenses, you can adapt the formula accordingly. For example, using the same range of expenses, the formula would be:
`=AVERAGE(IF(A1:A12 < 0, A1:A12))`

By utilizing the IF function within the AVERAGE function, you have the ability to filter and calculate averages based on specific conditions, offering you further flexibility in data analysis and insight extraction.

This example demonstrates how the AVERAGE function in OpenOffice Calc empowers you to refine your calculations and derive specific average values based on the positive or negative nature of the numbers in the dataset.

## Example 5: Averaging Cells with Errors

Working with spreadsheets in OpenOffice Calc may involve dealing with cells that contain errors, such as #DIV/0!, #VALUE!, or #N/A. These errors can occur due to various reasons, such as dividing by zero or incorrect data input. When calculating averages, it's often necessary to handle these error cells appropriately to obtain accurate results. The AVERAGE function in Calc provides a convenient way to average cells while ignoring those with errors.

Let's consider an example where you have a range of cells representing the scores of students in a test. However, some students did not submit their answers, resulting in error cells due to missing data. To calculate the average of the scores, excluding the error cells, follow these steps:

1. Select the cell where you want the average result to appear.
2. Type the AVERAGE function, starting with an equal sign (=).
3. Specify the range of cells containing the test scores data.
4. Append the function with the condition to ignore cells with errors using the IFERROR function.
5. Press Enter to complete the formula.

For example, let's assume the test scores are in cells A1 to A10, with some error cells. To calculate the average of the scores while skipping the error cells, you would enter the following formula:
`=AVERAGE(IFERROR(A1:A10,""))`

Remember to enter this formula as an array formula by pressing Ctrl+Shift+Enter. Calc will then calculate and display the average of the non-error cells in the selected cell.

The usage of the IFERROR function ensures that any cells with errors are treated as empty values, allowing Calc to perform the average calculation correctly.

By utilizing the IFERROR function within the AVERAGE function, you can conveniently handle cells with errors and calculate the average of cells containing valid numeric values. This feature proves especially valuable when working with datasets that may contain incomplete or erroneous information.

This example showcases how the AVERAGE function in OpenOffice Calc assists in handling errors and enables you to obtain accurate average values from datasets that may include cells with errors.
