1. Intro to Excel
CSCI-150

2. Introduction
Spreadsheets are applications used mostly to store, organize, calculate, and display numeric data
Tabular format: Divided into rows and columns
Rows are numbered
Columns are labeled with letters
Cells hold data (numeric or text), formulas or functions
Power:
Automatically reapplies formulas as data changes
Automatically adapts formulas when copied to new locations

3. Introduction Each Excel file or project is called a workbook
File  New  Blank Workbook
Each workbook contains 1 worksheet by default
Each cell in a worksheet may contain
Text
Numeric
Formulas with or w/0 (built-in) Functions

4. Rows are numbered
Columns are assigned letters
K6 is highlighted and formula is shown above the sheet – address is shown in upper left corner

5. Formulas Begin with an = sign May contain Constants
Single cell references: D5
Functions: AVERAGE, SUM, etc. …
Cell ranges: D5:E7
Connections: +, -, *, /, ^, AND, Or, NOT

6. Formulas
Once written for one cell, can use it for other rows or columns
No need to rewrite it
Place cursor on the small square in the lower right corner of cell
Hold on the small black that appears by clicking on the right mouse
Drag to desired cells
Notice how formula changes
If target cell is not close to cell holding formula
Highlight formula cell then Edit  Copy
Go to target cell then Edit  Paste

7. Formulas Importance of using cell references Relative addressing
Formulas can be updated automatically when copied to different cells
Formulas can be recalculated when referenced data changes
Relative addressing
A7 contains formula A5+A6
Copy to B7  ?
B7 is one column to the right of A7
Copy to C9  ?
C9 is two columns to the right of A7 and 2 rows below it

8. Formulas Want to refer to fixed position cells? Absolute addressing
Place a $ sign before row number  row does not change
Place a $ sign before column letter  column does not change
Both  cell is fixed
New formula

9. Functions As you enter the = sign
The name box changes to a listing of available functions
Functions applicable to ranges: SUM, AVERAGE, MAX, MIN, COUNT, COUNTIF

10. Conditional Functions
IF and VLOOKUP function
IF-ELSE
IF (condition, yes action, no action)
Enters one of two possible results in a cell based on condition
IF(G5>50000,10%,12%)
IF(F5=“F”,”Yes”,”No”)
Condition part be any equality or an inequality
Compound statements by using AND and OR
If worker last name is “Miller” and is full time then they would be eligible for a raise
==F(AND(F4="F",H4=“Miller”),"Yes","No")
The book says the opposite
Must use DateValue?

11. VLOOKUP Better if we have more than two options to select from
Must have an accompanying lookup table
VLOOKUP(x,y,z)
x = cell containing value to lookup
y = table range (top left and bottom right corners)
z = column in table containing the result to write --- 2
Table must be organized in ascending order from smallest to largest
One table entry must match the values being looked up
Direct match (equal one of the values)
Bounds match (table gives lower bounds of ranges)
Once the we get the value of the last cell before we cross the boundaries of range of the given value

12. Multiple Sheets A workbook can have many worksheets
Click on the tab for a sheet brings it to the foreground
Add new sheets
Right on the sheet tab  Insert
Delete sheets by clicking on their tab
Right on the sheet tab  Delete
Rename sheets
Right on the sheet tab  Rename (ONE WORD)
Rearrange sheets
Click on tab, hold down the button, and drag the tab to desired location

13. Multiple Sheets
When a cell referenced in a formula by row and column (e.g. C5)  in current worksheet
Reference cells in different sheets, add the sheet name followed by !
Make sure sheet name is a valid variable (1 string with no spaces)
Sheet2!C5

14. Cell Naming
A frequently used cell can be named so as not to have to refer to it by its address all the time
Type in name in Name Box
Hit Enter
A range of cells can also be named similarly by selecting it and proceeding as above
If you select a row or column with a title, the title is suggested by default
