SPREADSHEETS

2
SPREADSHEET A computer application program that arranges data into rows and columns, usually used to work with numbers and calculations.

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? 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.

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. 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 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? 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 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 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 Example: Example: Place a sum formula in Cell E2 to total cells B2:D2. 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. 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. 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. 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 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, 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 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 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. 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) 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. 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. 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. 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?

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. 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... 1.Click in the first cell you want to select 2.Then hold down the open apple key and click in the other cells that you want to highlight The active cell selected. A cell is activated by highlighting it. To highlight cells that are not together... 1.Click in the first cell you want to select 2.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 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

FORMULA HINT If you are asked to put in a formula and you can not figure out how to do it, activate another cell that already has a formula in it and look at the formula in the data entry bar at the top of the spreadsheet. CAUTION - Make sure the formula is the same operator that is being requested. For example, if the question ask for you to put in a formula that would multiply cells, make sure the formula you looked at was multiplying cells. DO NOT copy the same formula, you must type the correct cells that are being used.
