5 What is Excel? Excel is a spreadsheet program, allowing you to carry out calculations, make predictions, and analyse trends. It also allows you to produce visual representations of this information in the forms of graphs and use graphics to enhance your work. Getting Started how to log on You can access Excel from any of the computers in the libraries. You will need your username and password to log on to the network. To find your username your student ID card should be placed on the card reader at the Information Desk. Your password will be based on your date of birth and six randomly generated digits, but you can change this to something you ll be able to remember more easily. Exercise 1 Log on to the network using the instructions below. 1. Press Control, Alt and Delete simultaneously to log on. A Windows Dialog Box will appear. 2. Enter your username in the first space (in lower case letters). 3. Press tab or click in the password box (left hand click). 4. Type in your password. 5. Press return.. Top Tip See the Introduction to IT workbook for information on how to change your password. Exercise 2 Getting into Excel 1. Click on the Start button in the bottom left hand corner of the screen. 2. Move the arrow up to All Programs. 3. Then move it across to Microsoft Office. 4. Finally move it across to Microsoft Office Excel 2003 and click. The sequence to follow is demonstrated on the next page. University of Bolton

6 The Excel Screen When Excel has loaded, the screen display should look similar to the one below: Menu Bar Tool bars Help button Scroll bars University of Bolton

7 Top Tip To close the Microsoft Office online help, click on on the Getting Started bar. If you need help with Excel at any time, click on to restore the online help facility. How do I enter data into the worksheet? When you load Excel you will be presented with a blank worksheet. The worksheet is comprised of many cells, each of which can be activated by clicking on it. This is called the Active Cell. You can move around within these using the mouse or arrow keys on the keyboard. Each cell has an address, comprising a Column Letter and a Row Number e.g. A1. As you click in the various cells, this address appears on the left of the Formula Bar. Formula Bar Column Letter Active Cell Row Number Sheet Tabs A spreadsheet can extend into 3 dimensions through the use of multiple worksheets. These are accessed via the Sheet tabs. The entire spreadsheet (including all worksheets) is called a workbook. Data is entered into cells as either a label or a value. Labels are usually textual information i.e. headings of columns, dates. Their alignment in the cell is left justified. Values are numerical data, on which you may want to perform mathematical operations. Their alignment in the cell is right justified. University of Bolton

8 Exercise 3 1. Click in cell A1 and enter the title School of Witchcraft and Wizardry End of Year Results. 2. Before we input the column titles we need to make column A wider. To do this click in column A, then click Format on the Menu Bar, and then Column and Width. The Column Width box will be displayed as below. The number in the column width box is highlighted, ready for you to overwrite it. 3. Type 17, then click on. 4. Click in cell A3 and enter the title Students Name. 5. Click in cells B3, C3 and D3 and enter the titles shown below. 6. Now fill in the rest of the information given below. Your display should now look the same as the one above. Top Tip A quicker way to widen the column is to move your mouse over the line to the right of the column letter. You will see the double arrow. Click and hold down the left hand mouse button, and move to widen the column to the width required. University of Bolton

9 How do I save my data? When you have finished entering your data, you should save your work. From the Menu bar, click on File, then Save As. This will open up the Save As window as shown below. Exercise 4 1. Click in the box labelled Save In and select the drive you wish to save on. There are various drives available such as A: for floppy disks. It is good practice to save on both hard storage media, such as floppy disks, CDs and pendrives, and in My Documents, which is your network drive. 2. Click in the box labelled File name. Delete the default file name that Excel chooses and replace it with your own file name. We want to save our data using another name so type in Results. 3. Now click on. Top Tip Once you have saved your document and given it a name, all you need to do to save fresh changes is to click on on the toolbar. Remember to save your work at regular intervals. University of Bolton

10 How do I format cell contents? Cell contents in Excel can be formatted in a similar way to using a word processor. The important difference is that the formatting applies to a whole cell, not an individual character. There are many types of formatting that can be applied to the cell. In the exercise below we will look at the appearance of the cell. Examples of this are bold, underline, font and colour. Exercise 5 Using the data file Results we entered earlier, we will do some simple bold and underline formatting. 1. Enter two headings we will use later Student average in cell E3 and Module average in cell A Click in cell A1, then click Format on the Tool bar and then Cells. 3. Click on the Font tab if you are not already on it. 4. Click on bold in the Font style box, then click. Your title should now be emboldened. 5. Using the steps above make all your headings bold. 6. To underline your title click in cell A1, then click Format on the Tool bar, and then Cells. 7. Click in the Underline box and choose Single, then click. Your display should look like the one below. 8. Click to save your work. University of Bolton

11 Cell formatting Continued An alternative way to change the formatting of cells is to use the Tool bar. Click on Click on to embolden. to underline. This is usually the easiest way to alter the appearance of your worksheet, but it relies on the toolbar being available. Top Tip To make the formatting Tool bar visible if it is not displayed, click on View on the Menu bar, then click Toolbars and Formatting. Cell formatting is also used for many other purposes. e.g. to tell Excel what type of data is stored in the cell. i.e. numeric, text, date, currency. How do I use formulas? A formula is used when the value of a cell needs to be calculated. For example, formulae may be used to calculate totals or averages, produce percentages, or find the minimum and maximum values in ranges. Parts of a formula =sign indicates the beginning of a formula the average function cell references to tell Excel which cells to average University of Bolton

12 There are 2 items that occur in formulae and need explaining: 1. A range A range is a contiguous block of cells and is denoted in Excel by the cell reference of one corner of the block, a colon and then the cell reference of the diagonally opposite corner of the block. e.g. B5:D5 means the cells B5,C5,D5. A1:C2 means the cells A1,A2,B1,B2,C1 and C2. 2. A function A function is a predefined calculation that is given a name. There are many inbuilt functions in Excel. e.g. average, sum, count. In the example below, the function being used is Average. AVERAGE(B5:D5) performs the calculation (B5+C5+D5)/3. Exercise 6 Using the data we have just typed in we will calculate the total (or sum) of Harry Potter s marks. This will add up B5, C5 and D5. 1. Click in cell F5, to calculate the sum. i.e. add up the marks for Harry Potter. 2. Click on the formula bar and type =sum(b5:d5) then press return on the keyboard. Your display should now look like the one below: University of Bolton

13 Top Tip In this exercise we typed the range B5:D5 in on the keyboard. An easier way to do this is to select the range using the mouse. Exercise 7 Delete the contents of a cell. 1. Click in cell F5 and press Delete on the keyboard. The number in F5 will disappear. Exercise 8 1. Click in the cell E5, to calculate the average mark for Harry Potter. 2. Click on the formula bar and type =average(b5:d5) then press return on the keyboard. Your display should now look like the one below: 3. Click to save your work. University of Bolton

14 Exercise 9 1. Click in cell B12, to calculate the Module average for Herbology. 2. Click on the formula bar and type =average(b5:b10) then press return on the keyboard. Your display should now look like the one below: 3. Click to save your work. How do I copy formulas? Now we would like to calculate an average mark for the rest of the students. These don t have to be done individually. We can do it in one step by copying the formula. Exercise Click in cell E5, which is the formula we want to copy. 2. Press Ctrl C on the keyboard. The cell E5 will be highlighted with a dotted line. 3. Click in cell E6, then, using your mouse, select the range E6 to E Now press Ctrl V on the keyboard. The results will appear in the cells. Your display should now look like the one on the next page. 5. Click to save your work. University of Bolton

15 When you copy a formula to another cell, any cell references are automatically updated so that they refer to the cell in the same relative position. These are called relative cell references. So in the example we have just done (Exercise 10), if you click in cell E5 the formula is =average(b5:d5), whereas if you click in cell E6 the formula is =average(b6:d6). In some circumstances, a cell reference is written so that the value of the cell when it is copied does not change e.g. $B$5. This is called an absolute cell reference. Top Tip If you would like more information on absolute cell references there are some good books in the library. Just search for Microsoft Excel in the catalogue. Exercise Follow steps 1 to 5 in Exercise 10 to find the Potions and Charms module average. Your display should now look like the one below: 2. Click to save your work. University of Bolton

16 Exercise 12 Have a look at the average results we have just calculated. You can see there are rather a lot of decimal places. To display these as whole numbers we can use cell formatting again. 1. Click in cell E5, then using your mouse, select the Student average range E5 to E Click on Format on the Menu bar, then Cells. 3. Then click Number in the category box. 4. Change the number of Decimal places to 0, and then click. Your display should now look like the one below: Exercise Using the same steps as Exercise 12, adjust the Module average results to display whole numbers. Your display should now look like the one below: 2. Click to save your work. University of Bolton
