Lesson 5Exploring Function and Argument Basics
Objectives
2
• Use Insert Function.1• Key and point to enter
functions.2• Navigate with and create
named ranges.3• Use range names in functions.4• Explore function categories.5• Use a constant.6• Format data using icon sets.7
Using Insert Function A function is a built-in formula Functions do things automatically
that would be difficult or time-consuming
All Excel functions have syntax Syntax defines the parts of a function
and the order of those parts
Function Arguments An argument is the data required for
the function to complete its calculation A few functions that do NOT have any
arguments; =now() or =today() If a function has more than one
argument, the arguments are separated by COMMAS
Arguments can be: Cell references (individual cells or a range) Constants (a keyed value) Another function (a nested function) Range names
Use Insert Function The Insert Function button (fx)
opens a dialog box that lists Excel functions alphabetically or by category
The Insert Function button (fx) is at the left of the formula bar; the same button (fx) is also on the Formulas tab in the Function Library
When you click the Insert Function button (fx) the Insert Function dialog box opens You can search for a function, choose a
category, or selection a function from the most recently used
Keying and Pointing to Enter a Function
After you key a letter or two, you’ll see a list of functions that begin with those letters in Formula AutoComplete
Keying & Pointing to Enter a Function
As you key or select arguments, an Argument ScreenTip shows the syntax with the argument to be entered next in bold
Objective 3
Navigating With and Creating Named Ranges
8
A defined name is a name assigned to a single cell or to a group of cells
A defined name is also referred to as a range name or a named range
Navigating with and Creating Named Ranges
Why Use Named Ranges? You can use range names for
navigation You can use range names instead of
cell addresses in formulas Range names are easier to remember
than cell addresses You are less likely to make an error
when selecting cells Range names make formulas easier to
understand
Navigating with and Creating Named Ranges
Rules for Naming Ranges
Begin cell range names with a letter Do NOT use single-letter range names,
such as “n” Do NOT use range names that
resemble cell addresses, such as “A5” Keep range names relatively short Use uppercase letters, an underscore
to separate words Do NOT use special characters such as
hyphens (-) or symbols ($, %, &, #)
Naming a RangeDefine a range name with any of these methods:1. Click the Name Box, key the range
name, and press Enter.2. Click the Define Name button on
the Formulas tab. Key the range name and click OK.
3. Click the Name Manager button on the Formulas tab. Click New, key the range name, and click OK.
New Name Dialog Box
Name Manager Dialog Box
Creating Range Names Automatically
You can name several ranges at once
Deleting Range Names
Range names can be deleted. If you delete a name that is referenced in a formula, the formula cell shows #NAME?
Setting the Scope for a Range Name
When you define a new range name, you can specify if it pertains to a particular sheet or to the workbook. The SCOPE is a range name’s location applicability
Objective 4
Using Range Names in Functions
18
Using Range Names in Functions
When you key a display trigger, range names and functions appear in Formula AutoComplete
A display trigger is the first character in the range (or function) name
Press F3 to display the Paste Names dialog box
Using Range Names in Functions
You can redefine cells in a defined name. You can also change the name. Use the Name Manager dialog box for these tasks.
Objective 5
Exploring Function Categories
21
Exploring Function Categories
Excel function categories indicate the use and purpose of the functions
Exploring Function Categories
SUMIF is in the Math & Trig category. It sums a range of cells based on a particular criteriaThe SUMIF function has two arguments:
range – is the group of cellscriteria – is the condition that must
be met
Exploring Function Categories
AVERAGEIF is in the Statistical category. It calculates the arithmetic mean for a range of cells based on a criteria
Exploring Function Categories
PMT is from the Financial category. It calculates a payment for money owed.
Objective 6
Using a Constant
26
Using a ConstantA constant is a named value. It is created from the New Name dialog box. It can be used like any defined name.
Creating a Range Name List
You can paste a list of range names and constants as documentation
Use the Use in Formula button or from the Paste Name dialog box—F3
Choose Paste Names at the bottom of the list
Constant
Using Fill Across Worksheets
You can copy selected data from one worksheet to another when sheets are grouped
Group the sheets with the data to be copied on top and visible
Click the Fill button in the Editing group on the Home tab and choose Across Worksheets
Objective 7
Formatting Data Using Icon Sets
31
Formatting Data with Icon Sets
An icon set is data visualization with a group of three to five images that appear with or without a value in a range of cells
Editing the Icon Set Rule
Icon sets are based on rules that CAN be edited
Summary Formulas and functions are
calculations, and the names can be used interchangeably.
Formulas are user-created; functions are built-in and follow specific syntax or rules.
Arguments for a function or formula can be cell addresses, named ranges, constants, or another function.
Summary You can use the Insert Function
command to place built-in functions in the worksheet.
The Function Arguments dialog box provides help in choosing the arguments.
When you key a function name, Formula AutoComplete and ScreenTips appear to provide guidance in building the formula.
Summary Multiple arguments in a function are
separated by commas. Many functions ignore text, blank
cells, error values (#NAME?), and logical values (TRUE or FALSE).
A range of cells can be defined with a name.
Summary Use range names rather than cell
addresses for navigation and in formulas.
In a formula, key the first character of a range name to see existing names listed in Formula AutoComplete.
Range names must begin with a letter, cannot use spaces or special characters, and should be short and descriptive.
Summary Range names can be deleted,
changed, or redefined. Range names can be scoped to the
workbook or to a particular sheet. You can paste a table of range names
and cell references on the worksheet for documentation.
Summary
Categories classify Excel functions based on use and purpose. Some categories include sophisticated scientific, engineering, and business formulas.
The SUMIF and the AVERAGEIF functions add and average values only if they meet criteria specified in the argument.
The Financial function category includes PMT, which is used to calculate regular payments for money owed.
Summary A constant is a named value. It is a
value that does not change. A constant name appears like a
defined name in the Name Manager dialog box and in Formula AutoComplete.
Summary An icon set is data visualization that
displays an image at the left edge of the cell based on the value.
Icon sets can use three, four, or five images to represent the values.
