wheel to zoom in and out
hold down the ALT key and tap the TAB
key to flip between open programs (like
the last channel button on TV)
Microsoft Excel:Cells, Columns and
Rows
• Cells (the little boxes in excel)
– Hold numbers or text
– Contents viewed on edit line
– Named like battleship – column and row. Cell A6 is
named for where column A meets row 6
Basic Formulas with Excel
Excel Formulas
• Excel can be used as a big calculator
• Basic arithmetic (+, -, x , ÷ and yx)
• Operation symbols:
Addition: +
Subtraction: Multiplication: *
Division: /
Exponent: ^
Formulas Using Numbers
• Syntax: always begins with equals sign
– Example1 : seven times eight
• Choose a cell and type =7*8
• When you hit enter the number 56 will appear
– Example 2: four to the third power
• Choose a cell and =4^3
• When you hit enter the number 64 will appear
Formulas Using Cell Names
• you can use cell names as variables
• Example1: Seven times the value in cell B2
– Type =7*B2 (cell B2 will be automatically
outlined)
• Example2: the value in cell B2 plus the
value in cell B5
– Type =B2+B5 (both cells will be outlined)
Try this out….
• In cell B2 create a formula to multiply the values
of cells B5 and B7 and divide by 4.
– =B5*B7/4 answer should be zero
• Add numbers to cells B5 and B7
Basic Functions with Excel
Excel Functions
• Excel Functions do many things from
calculating an average to finding standard
deviation to combining several lines of
text.
Excel Functions
• Excel functions ALWAYS begin with an
equals sign:
• Form of an Excel function is:
=function_name(argument1,argument2… )
Arguments are additional pieces of information
Excel needs to do what you are asking it to do
Arguments are always separated by commas.
sum
=sum(number/cell_names)
• Function sum has one or more arguments
– number are actual numbers separated by
commas
– cell names are individual cell references
separated by a comma or a range of cells. A
range is shown using the first and last cell in
the range separated by a colon.
sum
using the autosum button
• button showing Σ (greek letter sigma)
automatically sums up the nearest range
of numbers it can find.
• The range must be continuous (no empty
cells) for Excel to automatically choose the
correct data
round
=round(number,num_digits)
• Function round has two arguments
– Number is a number or cell value you want rounded
– Num_digits is the number of digits you want rounded
to. Zero and negative numbers will round to whole
number place values. (0 round to ones, -1 rounds to
tens, -2 rounds to hundreds, etc.)
average
=average(range of cells)
• Average function has one argument: a range of
cells with numbers you want to average
– It is on the pull-down menu attached to the autosum
button
– Simple as autosum – just select the range you want
and hit enter
median
=median(range of cells)
• Median function has one argument: a range of
cells with a dataset from which you want to
determine the median
– It is NOT on the pull-down menu attached to the
autosum button
– Can type it in as above or use More Functions from
the autosum pull-down
– Could also use insert function:
fx
mode
=mode(range of cells)
• Mode function has one argument: a range of
cells with a dataset from which you want to
determine the median
– It is NOT on the pull-down menu attached to the
autosum button
– Can type it in as above or use More Functions from
the autosum pull-down
– Could also use insert function:
fx
mode
(continued)
• Mode will return the number that appears most
often in a data set.
– If there is no mode (no repeating numbers) Excel will
show #N/A
– Warning: If there is a bimodal set of data Excel will
show the mode of the first repeating number in the
set….
mode
(continued)
• If your data is as follows:
– The numbers 2 and 3 are
both modes: they both
appear twice but Excel
shows only 2 since it
appears first in the data
– Why? IDK, blame Excel.
range
there is no range function
• There is no one function that can get you the
range of a dataset. You must:
– Use several cells with functions to calculate it OR
– Combine several functions into a single cell to find it
– The simplest way is to subtract a =min function from a
=max function:
• =max(B2:B6)-min(B2:B6)
(no equals sign for the 2nd one)
Logical Functions
• Logical functions make decisions about
information in a cell based on conditions
you set and answer by displaying info
depending on the decision
• Conditions – criteria you set for Excel
– (i.e. is the cell =5, is the cell >14, etc.)
if
=if(logical test, value if true, value if false)
• If function has three arguments:
– 1. a logical test seeing if something is true or false in
a cell
– 2. a value that shows up if the logical test is true
– 3. a value to show up if the logical test if false
if (cont)
=if(logical test, value if true, value if false)
• Argument 1: logical test
– For the logical test argument you put a cell reference and a
condition
– i.e. you want to see if cell B2 is equal to 5. The first part of the
function looks like this:
=if(B2=5,
if (cont)
=if(logical test, value if true, value if false)
• Argument 2: value if true
– For value if true argument you put a number or text for Excel to
show if the logical test turns out to be true
– i.e. if cell B2 actually equal to 5 let’s say you want the word
EQUAL appear. The second part of the function looks like this:
=if(B2=5,”EQUAL”,
(remember, all text
must be enclosed
in double quotes)
if (cont)
=if(logical test, value if true, value if false)
• Argument 3: value if false
– For value if false argument you put a number or text for Excel to
show if the logical test turns out to be false
– i.e. if cell B2 does NOT equal to 5 let’s say you want the word
NOT EQUAL appear. The last part of the function looks like this:
=if(B2=5,”EQUAL”,”NOT EQUAL”)
(remember, all text
must be enclosed
in double quotes)
if (cont)
=if(logical test, value if true, value if false)
So if we take our example it looks like
this:
if (cont)
=if(logical test, value if true, value if false)
Hitting enter gives us the function result
which is EQUAL since cell B2=5
if (cont)
=if(logical test, value if true, value if false)
If we change the value in cell B2 to 8 it
gives us the function result which is
NOT EQUAL since cell B2 is no longer
equal to 5
Text Functions
• Functions you can use to manipulate text
in a bunch of ways
– UPPER function
– LOWER function
– PROPER function
– CONCATENATE function
upper
=upper(text)
• Function has one argument
– Converts text to all upper case letters
– Text is typed words/numbers OR the cell that
contains typed words/numbers
lower
=lower(text)
• Function has one argument
– Converts text to all lower case letters
– Text is typed words/numbers OR the cell that
contains typed words/numbers
proper
=proper(text)
• Function has one argument
– Converts text to all first letters upper case and
all the rest lower case
– Text is typed words/numbers OR the cell that
contains typed words/numbers
concatenate
=concatenate(text1, text2…)
• Function has several argument
– Combines text from multiple cells into one cell
– The arguments are cells with text OR text in
double quotation marks
Lookup Functions
• Excel can be used to look up information
in a table, similar to looking in a dictionary
or phone book
• A table is a list of data, each column
having its own unique info or field
vlookup
=vlookup(lookup_value,
table_array,column_number))
• lookup_value : a cell where you will type
the data that you want to seek on a table
• i.e. in the database below
I want to type a name in cell
A2 to get more info from the
table
vlookup
=vlookup(lookup_value,
table_array,column_number))
• table_array : information arranged in
columns and rows
• i.e. the table that the vlookup
function goes to find the
info in cell A2
vlookup
=vlookup(lookup_value,
table_array,column_number))
• column_number : column in the table that
you want excel to return
• i.e. column 2 will make vlookup
send the phone number back
into the function’s cell
Basic Formatting with Excel
Font Formatting
• Everything is the same as Word: font,
color, size, bold, italic, underline
EXCEPT
Formatting Borders around cells
Border Formatting
• Found on the Font section of the Home
ribbon.
• Can make a variety
of borders around
single cells or
groups of cells
Border Formatting
• Pre set border selections
appear on the pull-down menu
while a box with custom
settings can be found by
clicking More Borders on the
bottom
Alignment Formatting
• Allows you to line up text within a cell to
the left, right or center (like Word)
• Also allows you to align text
vertically within the cell – on the
top, center, or bottom
Alignment Formatting
• Examples:
Number Formatting
• Currency
– shows numbers with two decimals and a
currency symbol of your choosing (dollars $,
pounds ₤, yen ¥, euros €)
– On a pull-down menu off the
Number Formatting
• Fraction
– shows numbers as fractions or mixed
numbers
– On the pull-down menu
– You set the number of digits
for the denominator
Number Formatting
• Fraction (cont)
– Mixed numbers are entered by typing the
whole number, then a space, then a fraction.
– Mathematical operations can be done on cells
formatted for fraction
– The answers will appear as fractions
Number Formatting
• Scientific Notation
– shows large or small numbers
with a base and power using the
letter E to show exponent/power
i.e. – 4.7 x 103 becomes
4.7E+3 meaning 4.7 raised to
the +3 power
