  1. GRAPHS SPREADSHEETS Answer "What If" Questions CALCULATES

  2. Graphs "What If" SPREADSHEET A computer application program that arranges data into rows and columns, usually used to work with numbers and calculations. Calculate Formulas

  3. SPREADSHEET One of the main uses of spreadsheets is to forecast or to predict. Spreadsheets answer “What If” questions. Example: What if I made three more of my shots in the last game? What would my shooting percentage be?

  4. SPREADSHEET A spreadsheet is a calculator that you can use to model relationships in a problem. Maximum Multiply Cells Sum Formulas Divide Minimum Average Difference

  5. SPREADSHEET TERMS CELL - The intersection of a row and a column on a spreadsheet in which data can be entered. Cells are designated by their column letter and row number. Example: B4 ALWAYS put the column letter first, then the row number.

  6. CELL ADDRESS The name and location of a cell on a spreadsheet designated by the column letter and row number. A8

  7. CELLS Column Letter Row Number What is the cell address for the 4th Row, 3rd Column?

  8. C4 Remember . . . ALWAYS PUT THE COLUMN LETTER FIRST THEN THE ROW NUMBER

  9. RELATIVE CELL REFERENCE In a spreadsheet relative cell reference is similar to giving directions that explain where to go from a present location. It does this by specifying how far away a particular cell is from some other cell. Relative cell addresses follow the same directional instructions regardless of the starting position. Example: Four cells to the left of or three cells above

  10. RELATIVE CELL ADDRESS Place a sum formula in Cell E2 to total cells B2:D2. Example: Grab the fill handle and drag the formula down to cell E4 Formula from E2 will be pasted into cells E3 and E4 when the fill handle is released Directions Given From Relative Cell Address - Put total in 5th column, adding what is in the 2nd - 4th column of each row.

  11. ABSOLUTE CELL REFERENCE In a spreadsheet, a reference to a particular cell or group of cells that do not change, even if you change the shape or size of the spreadsheet, or copy the reference to another cell. Absolute cell reference always point to the same cell, no matter where the reference appears.

  12. ABSOLUTE CELL REFERENCE Example: $A$3 $A$3 is an absolute cell reference that always points to the cell in the first column and the third row. You know it is an absolute cell reference because of the dollar symbol before and after the column heading.

  13. #REF! Cell Reference Error Displays if formula is not correct If you attempt to paste a formula where there are not enough cells from the target cell to fulfill the required direction, the #REF! error message will appear in the cell.

  14. CELL RANGE A continuous group of selected cells. RANGE = B4:B15

  15. IDENTIFYING A RANGE OF CELLS Range - A group or block of cells Example - A1:A5 Cells that are located in rows one through five in the first column,

  16. COLUMN The vertical divisions of a spreadsheet Columns are labeled alphabetically

  17. COLUMN HEADING The lettered box at the top of a column.

  18. RESIZING COLUMNS To quickly re-size a column so that you can see all the contents within the cells, place the mouse on the border between cell headers until the cursor shows arrows ( ) , then click and drag the column divider to make it wider.

  19. COLUMN CELL ADDRESS Data in a series of cells arranged in a column will have the same letter in the address. Example: A2:A4 Read as A2 to A4

  20. ROW The horizontal divisions of a spreadsheet which are labeled numerically. ROW HEADING The numbered box at the beginning of a row.

  21. ROW CELL ADDRESS To indicate a row of data, use the beginning cell address and the ending cell address with a colon in between. Example: A1:G1(Notice a row will have the same number but a different letter)

  22. DELETING ROWS AND COLUMNS To delete an entire row or column, click on the heading. Do not try to click and drag across the cells especially if it is a large spreadsheet.

  23. DELETING MULTIPLE ROWS Multiple rows can be deleted at one time by clicking and dragging on the row headings.

  24. Quick Quiz Is C2,3,4 a correct column address?

  25. NO You must have a column letter and row number of the beginning cell and ending cell.

  26. QUICK QUIZ - QUESTION 2 What would be the correct way to write this column address (C2,3,4)?

  27. C2:C4 Data in a series of cells located in the third column (C) going from row 2 to row 4, should be written in this format. Remember to always include a column letter and row number with a colon in between.

  28. QUICK QUIZ - QUESTION 3 What would be the cell address for the 2nd row, 8th column?

  29. H2 Even though the question said 2nd row-8th column, you still always put the column heading before the row number. When figuring the 8th column, just go down the alphabet to the 8th letter.

  30. QUICK QUIZ - QUESTION 4 How would you identify the row that is highlighted below?

  31. A7:G7 A7 TO G7 would identify this row of data. Remember to always include a column heading first then the row number. Notice that a row always has the same number.

  32. Quick Quiz - Question 5 How can you highlight column B without clicking and dragging the entire column?

  33. Click on the column heading (B). Remember to highlight an entire column or row, click on the column or row headings.

  34. Quick Quiz - Question 6 What will display in the cell if you have a cell reference error?

  35. #REF! If you attempt to paste a formula where there are not enough cells from the target cell to fulfill the required direction #REF! will be displayed in the cell telling you that you have an error in the formula.

  36. QUICK QUIZ - QUESTION 7 What symbol do you add to a target cell address to establish it as an absolute cell reference?

  37. $ Putting a dollar sign in a cell address, references that particular cell and it does not change even if you move it to another cell. Example: $A$3 Once established as the target cell it will always point to the cell that is in the first column, third row.

  38. CURRENT CELL The active cell selected. A cell is activated by highlighting it. To highlight cells that are not together . . . • Click in the first cell you want to select • Then hold down the open apple key and click in the other cells that you want to highlight

  39. FILL CELLS Spreadsheets provide commands to help copy or generate data quickly. Examples: Fill Right - Copies contents of cells to the right of an active cell Fill Down - Copies contents of cells below the active cell

  40. FILL SERIES Generates a series of values based on the value in the active cell. Examples of fill series Other examples of fill series If you type Jan., then the spreadsheet can provide the command to fill right with Feb., Mar. etc.

  41. FORMATTING A SPREADSHEET CELL Refers to changing the way the information is displayed in a cell STYLE Applies many formatting changes at once. Example: A combination of shading, borders, etc. to give the spreadsheet a distinctive look

  42. MODIFYING CELL TYPE Changes the cell data type of one or more selected cells. Cell types in NCDesk CAUTION: If you can not change the cell type, the data in the cell is not valid for the new cell type (i.e.,changing to money when dates are in the cell).

  43. CELL TYPES IN NCDESK • Text - Words • Whole Number - Numbers without decimals • Decimal Number - Numbers with decimals • Money - Use when displaying money $14.96 • Date (MM/DD/YYYY) - Displays month, day, and year 10/23/2009 • Date (YYYY) - Displays year only - 2008 • True/False- Creates check boxes for yes/no • Header - Distinguishes as the cell heading • Function - Information Only

  44. FORMATTING CELLS Numbers in a spreadsheet can be formatted by the command Format, Cells Examples: • To show how dates will be displayed 3/14/2006, Mar 14, 2006, 3/14, 3/14/06, Mar - 06, 14 - Mar - 06, 14 - Mar • To show how many decimal places will be displayed 3.45678, 3.456, 3.45, 3.4 • To show how time will be displayed 1:30 PM, 13:30, 1:30

  45. CELL PROTECTION Once a spreadsheet has been created, you can protect cells so they can not be easily changed. Example: Creating a monthly budget The budget template may have how much you plan to spend each month protected so that it will not change and then you could add how much you actually spent.

  46. GRID Blank setup of rows and columns in a spreadsheet on which data is to be entered.

  47. GRAPH/CHART A visual representation of numerical data. Presents complex relationships clearly.

  48. TYPES OF CHARTS

  49. PIE CHART Used to show percents

  50. BAR CHARTS Used to compare data Can choose a horizontal or vertical bar chart
