    U5 kickstart U5 kickstart Presentation Transcript

    • Unit 5 OCR Nationals – LEVEL 3
      Kick Start
    • OK, you asked for it
      Remember there are NO Model Assignments for the Option Units, so I am winging it. For this Unit, however, I am also relying a little on the new textbook from PG, so we’ll see how that goes.
    • Scenario
      A local restaurant owner would like to expand their business. To qualify for small business support they have to show that they are managing their finances well right now.
      Time for drastic action – design a spreadsheet that covers income and expenses, and allows some level of modelling for additional financial planning
    • AO1: Design spreadsheets to meet the needs of an organisation
      You need to get the pen and paper out for this one! Design AT LEAST 2 linked spreadsheets for the organisation, sketches to include:
      Purpose
      Audience
      Layout & formatting
      Design sheets in form appearance/customised toolbars & buttons
      Calculations required
      Data entry messages
      Data validation and other appropriate messages
    • AO1 Hints
      Be very clear in your mind about the user for this one: it helps if you can picture them!
      Think about:
      Keep the worksheets simple in size & number so they are easier to work with & understand
      Avoid blank rows/columns if you can help it: many higher end functions will just stop if there’s a blank cell in the way.
      Sort data into appropriate orders so that functions work more effectively
      Keep names in two cells – one for first, one for last: it’s easier later.
      Oh – there’s more, but I’ve run out of space here...
    • AO1 Hints
      Sheets with the appearance of a form:
      Excel 07 has the Template Wizard, so those of you with that can play and have fun.
      The more pedestrian 03 version will need macros: we’ve met them before, for U3.
      Calculations required
      Follow protocols: formulae only refer to cells ABOVE them
      If a formula requires LOTS of raw data, move it to a separate worksheet and link the data to the sheet holding the formula.
      Formulae should be as simple as possible
      REMEMBER there are over 300 different functions in Excel – this is your chance to play with your new toys...
    • AO1 Hints
      Data Entry Messages
      Data Validation – settings, as you know already
      Valid and invalid data
      Input Messages
      Error Alert
    • AO1 grade guides
      For Pass – and therefore all the others:
      At least two linked spreadsheets;
      Design includes purpose, audience and spreadsheet layout
      Designs are appropriate
      Some calculations are defined.
    • AO1 grade guides
      For Merit:
      Spreadsheet designs are clear on the content
      Most calculations are appropriate
      Some data entry messages are identified
      Note the level of detail for this!
      For Distinction:
      Customisation elements are clear
      All calculations are clearly defined and appropriate
      All data validation and error messages required are defined
    • AO2: Produce spreadsheets according to the design
      Linked spreadsheets
      Relative, absolute, mixed cell references
      Named cells and cell ranges
      Cell formats
      Functions
      Macros
      Customised Toolbars/menus
    • AO2 Hints
      Linked spreadsheets
      Well you did this for U3, so this should be OK, yes?
      Named cells and ranges.
      It’s easier to locate and work with a cell if it is called ‘total’ rather than ‘DE4’ or whatever. Choose the cell, then where the cell reference is shown, highlight and type in the name of the cell – NO SPACES!
      You can do the sameto a group of cells, too,whoooo!
    • AO2 Hints
      Cell formats
      Include conditional formatting, just like for U3
      Date and time as appropriate (NOW function)
      Also consider:
      Text alignment
      Font formatting – bold/italic/underline/colour...
      Use the STYLE function to create a consistent view
      Cell colours and shading, borders.
      Cell merging!
    • AO2 Hints
      Functions to meet requirements:
      Here’s a summary, but there ARE 300 of them so I’m just picking my top, ummm, 4, or 11...
      References:
      HYPERLINKS
      LOOKUPS
      MATCH
      Mathematical:
      COUNTIF (and all its subsidiaries!)
      SUM
      CEILING/FLOOR
      Statistics:
      AVERAGE/MAX/MIN...
      RANK
      COUNT
      Logic:
      AND/IF/FALSE/NOT/OR...
      Note also we have the wonders of NESTED FUNCTIONS (!)
    • AO2 Hints
      Nested functions
      You can do as I do in my marksheet for you guys: bung in more than one function at a time. This is a more effective way to complete a task in one neat package, and it is a LOT easier if you are using named cells/ranges. You can squish up to 7 levels in each – but here’s one of the more straightforward of mine, identifying whether you’ve gained P,M or D:
    • AO2 Hints
      Data Validation
      Well you’ve done this a bazillion times so I won’t treat you like fools.
      Try to be more imaginative in this than you were in U3, OK? You can calculate what is allowed based on the content of another cell, or use a formula to calculate the value, and this could again make your product more powerful.
    • AO2 Hints
      Macros
      We’ve already played with these on U3, but here you get to play with the Big Boys...
      You can set styles for font
      You can set formulae and functions using macros
      You can set actions (like graphing)
      Customising the menu/toolbars – more overleaf on this one because this is more fun (but don’t tell the Network guys, because I don’t know what they’ll let us do..!)
    • AO2 Hints
      Menus/toolbars
      Now this may well do our heads in, because I don’t as yet know what settings will stick, and what won’t. We’ll just have to play it by ear. What a surprise..!
      Let’s start with some definitions:
      MENUS are lists of commands: e.g. File menu. The 07+ versions of MS products are short on menus, but you’ll see them in 03.
      TOOLBARS hold the buttons instead of lists of words: 07+ is hot on toolbars.
    • AO2 Hints
      Customising
      Well, you could change the lists on a menu? Bit simplistic, but can be essential if you’re sick of going through several stages to get to the same ‘format’ menu element, or whatever.
      OR, change the buttons on the toolbar: there’s a standardised option to do that on all the MS products, or you could write your own macro and stuff it on a button and be even more impressive!
    • AO2 grade guides
      For Pass – and therefore all the others:
      Produce the darn spreadsheets
      They should look similar to the designs
      Including use of:
      Cell referencing (absolute/relative)
      Named cells and ranges
      Different cell formats
      Functions
      Macros
      Some attempt to customise menus/toolbars
    • AO2 grade guides
      For Merit:
      Spreadsheet is close to designs
      Including additional use of:
      Multi stage functions
      Data validation
      Cell references across sheets
      Customised a menu or toolbar
      Note the level of detail for this!
      For Distinction:
      Design and spreadsheet are as one.
      Including additional use of:
      Nested functions
      Customised error messages
      Customised a menu and toolbar
    • AO3: use spreadsheet to process numerical data and present required information
      So there’s a surprise – it has to DO something.
      How?
      Use PivotTables?
      A PivotTable sorts and summarises data, combining and comparing large amounts of data – and then creates a new table which you can sort and rotate – and it’s relatively easy to create using the Wizard! 
      Using the ‘what-if’ element in 07, you could use Goal Seek when you know the result that you need, but not how to get there. So for example, you need a 50p profit – so what’s the price to the client???
    • AO3: use spreadsheet to process numerical data and present required information
      You could also use Solver (Tools – Solver and set the parameters)
      You could use the advanced filtering options
      Presenting the results:
      Cell formatting to make it easy to read?
      Cell width and height/merge&centre
      Graphs & Charts
      HARD COPY (yeah – what you see you gotta be able to print: headers/footers/titles/cells & row titles)
      Report Manager!
    • AO3 grade guides
      For Pass – and therefore all the others:
      Data processing is appropriate for requirements
      Print spreadsheets showing
      all data
      Fit on the page(s)
      Cell contents visible
      Headers/footers
      Graph/charts
      PivotTables
      Filtered results
      Macros
    • AO3 grade guides
      For Merit:
      Good use of functions/formulae
      Printouts are clear and easy to understand
      For Distinction:
      Results of analysis are easy to understand: not just the ‘before’ but also the ‘after’!
    • AO4: Produce user documentation and technical information
      Well you’ve just done this for U4 so here goes:
      Ideally your user guide should cover the vast majority of the processes, including screenshots and explanations so that a fairly clued-up user could use the spreadsheet without you
      Your technical guide should cover ALL details of numerical processing methods, screenshots of macros, data validation, details of software and hardware required.
    • AO4 grade guides
      For Pass – and therefore all the others:
      User guide covers some of the processes so a relatively clued-up user could get on with your product
      Tech guide identifies
      Numerical processing methods used
      Macros
      Data validation
    • AO4 grade guides
      For Merit:
      User Guide includes text & screenshots covering some of the processes so a relatively clued-up user could make decent use of the spreadsheet
      Tech Guide gives details of
      Numerical processing methods used
      Macros
      Data validation
      For Distinction:
      User Guide does the lot using text & screenshots
      Tech Guide covers additional info on hardware and software, and any other resources required
    • AO5: Test the spreadsheet
      Usual stuff – test it using the full range of valid and invalid data, check for all messages – and make ALL necessary changes so it’s wonderful. Oh, and it works.
    • AO5 grade guides
      For Pass – and therefore all the others:
      Simple test plan covers that the spreadsheet does what it should from the spec.
      For Merit
      Evidence provided that the plan adequately tests the functionality of the spreadsheet (i.e. how well does it do what it should?)
      Make some changes to make it work as it should.
      For Distinction
      A detailed plan testing ALL aspects of the spreadsheet, showing valid & invalid input, expected input, and any error messages
      Make all changes so it works as it should
    • AO6: Evaluate the spreadsheet
      To what extent does it do as you said it would? And, no, just like all the others, you cannot just type, ‘I done it good!’
      You also need to suggest improvements and refinements, and the greater the detail the better the grade...
    • AO6 grade guides
      For Pass – and therefore all the others:
      A brief and not always accurate evaluation in relation to user needs. (I done it right)
      For Merit
      A detailed and accurate evaluation showing how well it meets user needs.
      A detailed description of improvements for the user.
      For Distinction
      A comprehensive evaluation of how well it does the do.
      Detailed improvements and recommended refinements
