    Worksheet 1: OrientationWe need to cover 3 units this year to gain the external qualification. Webwise is one, Excel andWord are the others. You will be able to show how good you are at logical thinking with Excel farbetter than with Webwise and Word but you will need to concentrate harder.

    We did some work on Excel last year, but its worthwhile taking five or ten minutes to re-familiarise yourself with the general layout of the application. All the commands available in Excelcan be found in the menu bar at the top of the screen. The underlined letter is the reference letterto the command when pressing theAlt key to access the menus, meaning that combinations ofkey presses can be used to run any command not covered by the shortcut keys. For example, toaccess the File menu, we pressAlt+F, since the F is underlined in File.

    TaskOpen Excel and save a new file with the name Notes. Create a table, showing command incolumn A, the shortcut key in column B (if one exists) and the menu reference letters incolumn C for the following commands:

    New, Open, Save, Print Cut, Copy, Paste Select All, Undo, Repeat Bold, Italic, Underline Function KeysAlso, try and locate all the taskbar buttons corresponding to the above commands. To do this, holdyour mouse pointer over the iconbut dont click and in a few seconds a small yellow boxshould appear telling you what the command is.

    Hints and Tips Pressing F1 brings up Help dialog box. This allows you to ask questions of the Answer Wizard

    or browse the contents and index. The Office Assistant still exists in Office 2003 but requiresactivating by selecting Show the Office Assistant in the Help menu. The assistant cananswer questions posed by you, jump in to offer you a tip or a handy shortcut via a little lightbulb lighting up and can animate for your personal pleasure!

    Shift + F1 accesses the WhatsThis?command, denoted by a question mark next to thepointer. If you click on anything that you want to know about, a yellow box appears to tell youwhat the command is and what is does.

    A list of shortcut keys for Excel can be found under Keyboard Shortcuts in the index of the helpfile.

    Note: These commands are under Cells in the Format menu

    The assistant is annoying after a while, and it begins to get in your way, don't worry:

    clicking with the right mouse button on the assistant and selecting Hide can turn off theassistant. When the assistant is turned off, commands such as F1 still bring up help menus.

    If you have accidentally turned the assistant off, click on Show the Office Assistant from theHelp menu.

    Worksheet 2: Spreadsheets

    It is important that you know how to enter data, format it and move around thespreadsheet effectively.

    Task1. Put todays date into cellA1, in the form dd/mm (e.g. 08/11).2. Use the fill handle ( this bit) to drag the border down so that it covers cells

    A1 toA7: this should copy the day, date and month of the next seven days intocolumn A.

    3. Copy the dates right into column B. Then convert the dates in column B to theform ddd (e.g. Thu).

    4.

    You should now have a table showing the days and dates of the next week. Nowchange the column order by moving all the weekday cells to column A and all datecells to column B by using the cells borders.

    5. Try using all the different ways you can think of to move cells around the worksheetand find the one that suits you best. Using keyboard shortcuts are often the mostefficient method while most laborious mouse movements can be eliminated.

    6. Press Ctrl + Home to select cellA1. Holding down the Shift key, use the cursorsto move the selection down to B7 so that all the data is selected. Hit Ctrl + Xto cutthe info, select Sheet2 from the tabs at the bottom of the screen, then Ctrl + tomove to the far right of the sheet, move the cursor one space to the left then pressCtrl + Vto paste the information.

    Extended WorkThink of several ways to navigate between cells. In your Notesspreadsheet, create a list ofmethods of navigation between cells and a description of each method. There are someexamples to start you off below see if you can come up with at least 5 more! Some canalready be found on this page.

    Method Description

    Ctrl+ Moves to the right-hand edge of the worksheetPgDn Moves down a page of cells at a time

    Ctrl+End Moves to most bottom-right hand cell with content

    These drag and drop methods are fine if you want to move or copy cells shortdistances but if you needed to move a block of cells to the other side of the worksheet, ittakes too long to scroll that far. Also you cant drag and drop onto different worksheets,workbooks or applications. However, this is easily achieved by using the cut, copy andpaste functions.

    Worksheet 3: Spreadsheet Formatting

    Excel can be used to present tables and charts. This worksheet will guide you through creatingand formatting a Gantt Chart. AGantt chartis a table which shows the scheduling for a project.Gantt Charts are an important aspect of some year 11 controlled assessments (coursework).

    TaskYour task is to create a Gantt chart for a school design and technology project.

    1. Fill in column A from cellA2 downwards with theheadings opposite, leaving a gap between eachone (i.e. cells A3, A5 etc are blank):

    2. The project will take 10 weeks, so fill cells B1 to K1with Week 1, Week 2 etc

    3. Make your text have font Courier New and make it

    bold. Make sure all your text fits in into the cell.

    4. The Gantt chart will show the estimated time for completing parts of the project withgreen rectangles and the actual time taken with red rectangles .For example, analysis of problemmay have taken 2 weeks when it was expected to take 3:

    Complete your chart using the following data:

    Expected time(week no. - inclusive)

    Actual time(week no. - inclusive)

    Analysis of problem 1 3 1 2

    Design of solution 3 5 3 5

    Development 5 6 6

    Manufacturing 6 9 6 10

    Testing 9

    10 10

    11Evaluation 10 12

    Headings: Analysis of problem Design of solution Development Manufacture Testing Evaluation

    Extended WorkUse the other formatting features of Excel to improve the look of your chart. You could try:

    rotating the Week headings through 90 degrees using the Orientationbox:

    using the merge cells button to add the number of weeks to thecentre of each red and yellow bar. For example:

    using the cell borders button to create a grid for your chart

    Worksheet 4: Formulae (1)

    Formulae are an essential part of spreadsheets. They are used to perform mathematicalcalculations, usually based upon some inputted data. We will create some fantastic stuff later, withonly a very small amount of maths, but this worksheet is for practising the logic in your formulae,so youll find it easiest if youre working with in pairs, with someone good at maths.

    Task 11. Start a new sheet and type in the formula that puts todays date into cellA1.2. Put a formula into cell B2 to work out which day of the week it is today (Excel uses 1 for

    Sunday, 2 for Monday, etc.). Then do it again to work out on which day of the week youwere born.

    HintUse the now()function for todays date and the weekday()function to find out the day.

    Task 2An example of a quadratic equation is y=2x - 2x + 3. Treat cell D1 as containingx, and type aformula into cell D2 that works out what y is. Use the following to check your formula:

    When x is 1, y should give 3 When x is 5, y should give 43 When x is 0, y should give 3

    Task 3 (Harder)1. On a new sheet, type Power:into cellA1 and type 2into cell B1. In cellA3 type 1.2. Using Excel's relative addressing, think of a way you can fill down from cellA3 so that you

    have numbers from 1 to 20 in cellsA3 toA22.

    3. In cell B3, type in a formula which will calculate cellA3 to the power of cell B1.4. Now make Excel repeat this function so that cell B4 containsA4 to the power ofB1, B5

    containsA5 to the power ofB1, etc. Note: do not hand type all the formulae!

    5. Now try changing the power value in B1. The whole sheet should update!Hints

    To perform a power ofcalculation in a cell formula, use the '^' symbol (Shift-6). i.e. 4 ^ 2 =16

    In Task 3, parts 2 and 4 you will need to use fill down ( drag this down!) In Task 3, part 4, you will need to use absolute addressing by using a dollar sign ($) in the

    formula. Bodmas works, but this is ICT not maths, so =2*(A3^2)-(2*A3)+3 is easier to understand

    and correct than =2*A3^2-2*A3+3, even though both work.

    Remember that all formulae should start with an equals (=) sign!

    Worksheet 5: Formulae (2)

    This sheet will show you how formulae can be used to work out useful information when modellinga situation. One of the most common uses of spreadsheets is to predict what will happen in certainscenarios ("what-if" scenarios).

    Task 1Suppose you are organising refreshments for your school play and that you are going to buy:

    A 4-pint carton of milk costing 1 A bag of sugar costing 1 Teabags costing 0.01 each Plastic cups costing 0.02 each

    Set up a spreadsheet where you can vary the amount of people buying a cup of tea (for 50 pence)and the total profit is automatically worked out.

    Task 2Using the information from Task 1, plot a graph showing the income and expenditure of therefreshments stand (using a Scatter graph with data points connected by lines without markers),with the X-axis showing the number of customers and the Y-axis the income/cost.

    Use this graph to calculate how many customers are needed to make a profit of 10. Your X-axisshould have values of up to 80 customers.

    Assume that the carton of milk and sugar are enough for every person.

    Extended WorkTry extending your spreadsheet so that you can see what happens if the cost of a certain itemchanges (use a cell to contain the value of each product). Also, use a cell to store the cost ofa cup of tea. How many customers would be needed for 10 profit if more expensivepolystyrene cups were used at 0.04 each? How much would a cup of tea need to be if it isrequired that 10 profit is made from 50 customers?

    Worksheet 6: Formulae (3)

    Task 1A gambler puts 10 one week into a local lottery (put Week 1in cellA1 and the amount in cell

    A2). The lottery produces a random number from 0 to 1 (use the RAND()function in cellA3).If the number is larger than 0.5 he increases his money by 10%, otherwise he reduces it by10% (put the formula for this in cell A4). The next week he puts the proceeds from the weekbefore (fromA4) plus the same amount again (from A2) into the same lottery the next week(use columnB). Repeat this for week 3 (ensuring you use the figures from A2 and B4). Theprocess repeats for all 52 weeks of the year (you will need to repeat this up to column AZ).

    Use row 5 to calculate how much the gambler would have if he simply saved his money eachweek. Plot a graph of the resulting monies. Use F9 to re-calculate the random numbers, andsee if you can spot a pattern.

    Task 2 A shopkeeper is using a spreadsheet to monitor his items. Copy and extend this table byadding at least 5 more rows containing your own items, and using formulae whereappropriate. Protect all the cells except those for how many Sold, Item Revenueand ItemCost; they can then be altered if needed.

    Resource Sold Item Revenue Item Cost Item Profit Subtotal Costs Subtotal Profit

    Jam 67 1.05 0.60 0.45 40.20 30.15

    Fruit Cake 45 3.00 1.50 1.50 67.50 67.50

    Shortcake 107 0.80 0.15 0.65 16.05 69.55

    Tea 276 0.20 0.07 0.13 19.32 35.88

    Total 495 143.07 203.08

    Extended WorkUsing Excel's built-in functions, try calculating the MAX and MIN values which the shopkeepercan use to see which item generates him most profit and which item generates him least.

    The shopkeeper also wants to know the proportion of sales of each product. Which kind ofchart would be suitable for this? Try getting Excel to generate such a chart from the Solddata.

    Anifstatement can be performed asfollows:=IF(item = value, output1, output2)This says that: IF item = value

    THEN give output1ELSE give output2

    =IF(Random_part>0.5,Amount_bet*1.1,Amount_bet*0.9)or=IF(C5>0.5,C2*1.1,C2*0.9)

    Worksheet 7: 'If' function

    'If' statements can be used within formulae to change a formula depending on somecondition. This can be useful in many situations.

    TaskA building society is awarding bonuses to their mortgage sales representatives. Theirbonus is based on the amount of sales they generate for the building society. If theyachieve less than 100,000 of sales then they do not get a bonus. If they achieve100,000 to 115,000 of sales they get a bonus of 10% of their salary. If they achieve115,000 to 130,000 of sales they get a bonus of 15%, and if they achieve over130,000 they get a bonus of 20%.

    1. Copy the data opposite into a newspreadsheet

    2. Devise a formula involving IF statementswhich calculates whether each sales repgets a 0%, 10%, 15% or 20% bonus.

    3. Fill down to complete the bonus column forall sales reps. Ensure all bonuses aredisplayed as percentages.

    4. Calculate the total salary for each sales rep by creating a formula which adds theirbonus to their original salary.

    You may need to nestyour if statements. That is, use one if inside another. Forexample:

    IF(item = value1, IF(item = value2, output2, output3), output1)

    Extended WorkThe company management does not want to spend more than 300,000, including bonuses, ontheir sales reps wages. Extend your spreadsheet so that the management can vary the bonuspercentages for each range of sales:

    < 100,000 100,000 to 115,000 (inclusive) 115,000 to 130,000 (inclusive) > 130,000

    and see the effect this has on the total salary going to their sales reps. Is there any room togive those achieving < 100,000 sales a small bonus, in an effort to maintain staff morale?

    The median of a set of values is the value that occurs in the middle of the list:there should be as many values less than, and greater than, the median value.

    Worksheet 9: Performing Calculations Mark Sheet

    Excel is commonly used for performing relatively simple calculations. This worksheetrequires the use of formulae and formatting techniques to produce a mark sheet for aclass' exams.

    Task - Class exam results

    Using the class data shown here, producethe percentage for the two papers, producethe overall percentage (equal weighting),and show the average and median for theclass.

    Before Simon Suller, insert a new row intothe worksheet (by selecting the Simon Sullerrow and then clickRow, from the Insertmenu) and add yourself, with your ownchoice of marks.

    You may have noticed that the names are nolonger in alphabetical order (if they are stillin alphabetical order, arrange them so thatthey are not!). To arrange them in order,select the whole table of names, then select

    Sort from the Data menu, and select to order by column 2, the pupil's surname. Your

    data should now be in alphabetical order!

    Extended Work

    To pass the exams, each pupil must gain an average of at least 50%. Add a column afterAveragewhich states either Pass or Fail (calculated using a formula that refers to eachpupil's average mark).

    The pupils who fail must retake both exams. Make up a second pair of marks for eachpupil who has failed and calculate their average as before.

    The marks for the year are calculated as follows:

    If a pupil passes, their mark is their average percentage. If a pupil fails, their mark is of the average percentage of their retakes.

    Devise a formula to calculate the final marks for each pupil and add this as a column.

    Worksheet 10: Advanced Task Timetable

    Now that you have the basics under your belt, it is easy to create a wide variety ofspreadsheets to solve or automate many simple, everyday tasks.

    TaskCreate a schedule or timetable to show: What: what has to be done Where: where you need to do it When: at what time it should be done Who: who it should be done with

    Complex timetables can be implemented by using logical formulae to change what a celldisplays depending on the date. This means that a small grid of times and days can bemade to display your weeks schedule depending on the date.

    The timetable below also uses a look-up table to show the weeks start and end dates byusing the VLOOKUP()function.

    Locking all the cells apart from input boxes means that the cells cant accidentally bedeleted.
