# Perform calculations on data

In this chapter form Microsoft Excel 2019 Step by Step, author Curtis Frye guides you through procedures related to streamlining references to groups of data on your worksheets and creating and correcting formulas that summarize an organization’s business operations.

Excel 2019 workbooks give you a handy place to store and organize your data, but you can do a lot more with your data in Excel than just store it. One important task you can perform is to calculate totals for values in a series of related cells. You can also use Excel to discover other information about data you select, such as the maximum or minimum value in a group of cells. And if you make an error, you can find the cause and correct it quickly.

Often, you can’t access the information you want without referencing more than one cell, and it’s also often true that you’ll use the data in the same group of cells for more than one calculation. Excel makes it easy to reference several cells at the same time, so you can define your calculations quickly.

This chapter guides you through procedures related to streamlining references to groups of data on your worksheets and creating and correcting formulas that summarize an organization’s business operations.

## Name groups of data

When you work with large amounts of data, it’s often useful to identify groups of cells that contain related data. For example, you can create a worksheet in which columns of cells contain data summarizing the number of packages handled during a specific time period and each row represents a region.

Instead of specifying the cells individually every time you want to use the data they contain, you can define those cells as a range (also called a named range). For example, you could group the hourly packages handled in the Northeast region shown in the preceding image into a group called NortheastVolume. Whenever you want to use the contents of that range in a calculation, you can use the name of the range instead of specifying the range’s address.

If the cells you want to define as a named range have labels in a row or column that’s part of the cell group, you can use those labels as the names of the named ranges. For example, if your data appears in worksheet cells B4:I12 and the values in column B are the row labels, you can make each row its own named range.

If you want to manage the named ranges in your workbook—for example, to edit a range’s settings or delete a range you no longer need—you can do so in the Name Manager dialog box.

2. In the Defined Names group, click Create from Selection.

4. Click OK.

To edit a named range
