Introduction to functionsFinding functionsCommon FunctionsStatistical Functions

FormulasFormulas in Excel

They always start with an equal sign (=)Example:

Almost always contain some mathematical operators:

- + / * ^Order of operations is important! Should be the same as you recall from Math classes for the most part. Brackets, Exponents, Division, Multiplication, Addition, Subtraction (BEDMAS).

Simple Example


In Class Lab

7

What we’ll learn:How to create formulasHow to copy formulasWhat relative, absolute, and mixed cell

references are


Questions on Lab?

8

You should know:What a formula isWhat the fill handle is, what it looks likeThe difference between relative, absolute,

and mixed references


The Fill Handle

9

When used it will copy the values/functions/formulas from one cell to another


Cell References

10

Relative – will change relative to where it’s copied/pastedA1

Absolute – will not change when copied/pasted around$A$1

MixedA$1 $A1

The “$” (dollar sign) indicates to Excel that you’d like that portion of your cell reference to remain ABSOLUTE

Introduction to FunctionsWhat we’ll learn:

What is a function?Methods of creating functionsHow to Find FunctionsIntro to Basic Statistical Functions

What is a function?“A pre-constructed formula that makes

difficult computations less complicated”

Functions take values as input, performs an operation, and outputs a value.

Most used function?SUM: Adds up all numeric entries within a range of

cells and displays the results.

=A1+A2+A3+A4+A5 =SUM(A1:A5)

Finding FunctionsGuess how many functions are available?Categories of Functions Available:

There is a way to search for functions, I will show you how in our lab!

Questions on Functions?You should know:

What a function is, how it’s different than a formula.

How to find and use Excel’s built in functions.Understand how the AutoSum and Insert

Formula tools work.


Using AutoSum ()

18

Automates the SUM functionClick the cell where you want the resultClick AutoSum buttonSelect the range of cells you want to sumPress Enter to complete


Basic Statistical Functions

19

Perform a variety of calculations to aide in decision making processAVERAGE calculates the average of a range

of numbersMIN calculates the minimum value in a rangeMAX calculates the maximum value in a

rangeCOUNT counts the number of values within a

rangeMEDIAN finds the midpoint value in a range


Date Functions

20

TODAY function places the current date in the selected cellUpdates when file is opened again

NOW function displays current date and time, side by side

Usage:=TODAY()=NOW()

Introduction Logical FunctionsA Special Breed of Functions…Return an answer when a particular condition is

true.One of the most common, and easiest to

understand is the “IF” function.Format:

IF(logical_test, value_if_true, value_if_false)

“If true output ‘value_if_true’, if false output ‘value_if_false’”

IF FunctionFormat:

=IF(logical_test, value_if_true, value_if_false)

Example:=IF(B2=5,“5 Cats!”,“Not 5 Cats!”)

IF Function=IF(logical_test, value_if_true, value_if_false)

Notes:value_if_true and value_if_false can contain

text, a value, a formula, or a nested function.if you are comparing for text be sure to

enclose it in quotes (“”)

Comparison OperatorsIn order to use the IF statement we need to

make a comparison.

Comparison Operators available in Excel:= Equal<> Not Equal< Less Than> Greater Than<= Less Than OR Equal To>= Greater Than or Equal To

Lightening Review

=IF(B1=“Cats”,25,10)

=IF(C4<>2,”Yes”,”No”)

=IF(A4=“Family 2”,2,0)

=IF(MAX(D2:D4)>=30,”Abuse?”,”Safe!”)

25No

Abuse?


VLOOKUP

26

Allows for lookup within a vertical table of information

Well suited for large tables of data, such as tax tables

Has three arguments:a lookup value stored in a cella range of cells containing a lookup tablethe number of the column within the lookup

table that contains the value to return


VLOOKUP Example

VLOOKUP Example

Financial Functions

29

Used for decisions involving payments, investments, interest rates, etc.

Common functions:PMT – used to calculate loan paymentsFV – used to calculate the “future value” of an

investment


PMT Function

30

Used to calculate loan paymentsHas three arguments:

the interest rate per periodthe number of periodsthe amount of the loan

Computes the associated payment on a loan

=PMT(periodic rate, number of pay periods, amount of loan)

=PMT(.09/12, 36, -14999)


FV Function

31

Used to determine the future value of an amount, such as an investment

Has three arguments:The interest rate (also called the rate of return)The number of periods (how long you will pay into

the investment)The periodic investment (how much you will

invest per year)

=FV(periodic rate, number of pay periods, investiment)

=FV(.10,36,-2000)
