2. An Array of Cells Spreadsheet is an array of cells
Lines are part of GUI (delineate cells)
Some entries appear to “straddle” cells

3. Sorting the Data
Sorting is common operation
First, highlight cells

4. Sorting the Data Sorting under “Data” tab
Order can be ascending or descending

5. Sorting the Data Sorting algorithm orders by first letter
Each cell entry is “atomic”

6. Adding More Data to the List
Can format entries as in word processors
italics, bold, font styles, font sizes, justification, colored text and so on
Formatting ops under “Home” tab

8. Naming Rows and Columns
Naming scheme
Columns use letters
Rows use numbers

9. Naming Rows and Columns
Allows us to refer to a
whole column by letter
entire row by number

10. Naming Rows and Columns
Reference block of cells (cell range)
E.g., “B2:D7”

11. Headings
Often give headings for rows and columns

12. Common Spreadsheet Operations

13. Computing with Spreadsheets
Usu. process numerical data
Numerical data is usu. associated with text

14. Writing a Formula Formulas start with “=” “= F2 * 0.621”
Operators: +, -, *, /, ^

15. Writing a Formula

16. Writing a Formula
Formulas are recalculated when referenced cells change in value
H2 holds a formula, not text or a number
“= F2 x 0.641”

17. Repeating a Formula Would like to repeat computation down column
Enter them like first
Copy/Paste
Filling

18. Copy/Paste
Select cell (^C)
Highlight destination range
Paste (^V)

19. Copy/Paste Note updated references Original cell: F2 * 0.621
Next cell: F3 * 0.621 …

20. Filling Filling is another way to copy info.
Note “fill handle” in lower-right corner

21. Filling When handle is grabbed, it becomes a +
“Pull” handle down column (or across row)

22. Transforming Formulas: Relative Versus Absolute
Spreadsheet automatically transforms formulas as it pastes/fills them
Two types of cell references
Relative (F2)
H2 = F2 * 0.621
Absolute ($F$2)
H2: = $F$2 * 0.621

23. Relative Versus Absolute

24. Relative Versus Absolute
Absolute references aren’t adjusted
Four cases for references F2
$F2
F$2
$F$2

25. Cell Formats
Readability
E.g., # digits

26. Typical Formatting GUI

27. Cell Formats GUI options Type of info (Category) Number
# decimal digits
“1000s” separator
Display of negatives

28. Functions
Common summary operations
sum
average
max
=max(J2:J7)
min

29. Functions fx : insert function
Computation value inherits formatting of cell
Dragged fn brings its formatting with it

30. Filling Hidden Columns
Hidden columns between G and J
Fns still present

31. Charts Graphical representation Select range Insert tab
Various chart types

32. Charts Chart types Headings detected Value range determined Legend
Horizonal axis
Value range determined

33. Daily Spreadsheets Use of spreadsheets Performance in exercise program
Budgets
Record of favorite team’s successes
Save records generated while online banking
Address books

34. Solving a Problem of Personal Interest
Scenario
Time Zone Cheat Sheet
Internet chatting with friends

35. Series Fill Handling of days, dates, and times
Adding 1 to Sunday results in Monday
Adding 1 to January 31 results in February 1
Adding 1 to 11:00 pm produces 12:00 am
Fill handle or “Fill Series”

36. Time Zone Cheat Sheet

37. Getting Started

38. Solving a Problem of Personal Interest
Scenario
Paying Off Loan
5% interest rate
To decide how much to borrow, create a spreadsheet of monthly payments required for different amounts borrowed for different times

39. Paying Off a Loan Initial Setup

40. Paying Off a Loan “Payment” (PMT) computation Inputs
Monthly interest Rate
Number of payments (Nper)
Present value or the amount of the loan (Pv)

41. PMT GUI

42. Conditional Formatting
Format dependent on criteria
Home tab

43. Tab-Delimited Data Import foreign data Tab-delimited text
M# Name Major
1111 Homer Simpson Nuclear Eng.
2222 Lisa Simpson Music
Can copy and paste into spreadsheet

44. Tab-Delimited Data
Copying an HTML table
Depends on browser

45. Arranging Columns Manipulating rows and columns To re-arrange columns
Insert a new empty column
Cut and paste from old to new

46. Summary Array of cells Cell referencing Data types Formulas Formatting
Absolute, relative, ranges
Data types
