3. To put your footer here go to View > Header and Footer 3 Contents Introduction of the ideas Practical work using the statistics add-in, called SSC-Stat Practical work using SSC-Stat for data analysis Discussion and review (The SSC-Stat software may have to be installed)

4. To put your footer here go to View > Header and Footer 4 So far with Excel You can organise data (Sessions 9 and 10) so it is ready for analysis You can do some statistics (Sessions 4 to 8) Tables and graphs Sort, Filter, Tables, Charts and more charts

5. To put your footer here go to View > Header and Footer 5 A statistical add-in Now we add to Excels statistical capabilities We use an add-in called SSC-Stat It provides an additional menu in Excel: An additional menu with more facilities for organising, charting and analysing data

6. To put your footer here go to View > Header and Footer 6 What is an add-in? Excel is a very powerful spreadsheet package But no package can have everything So Excel also provides facilities: For users to add extra components to Excel These are called add-ins And are provided by 3 rd party suppliers They are not part of Excel when it arrives There are many add-ins for statistics They enhance Excels statistical capabilities We are providing one called SSC-Stat Is SSC-Stat already installed in your Excel? If so, you will see the extra menu shown earlier

7. To put your footer here go to View > Header and Footer 7 Installing SSC-Stat? If SSC-Stat is not installed in your Excel You need to install it Installing SSC-Stat is a 2-stage process There is a demonstration on the DVD/network First install the software on your computer Find it on a DVD, your network, or the SSC website Then go into Excel And use the Tools => Add-ins menu To tell Excel you would like this add-in to appear Once SSC-Stat is installed into Excel It will appear each time you use Excel So you only need to install it once

8. To put your footer here go to View > Header and Footer 8 How to learn about new software A good way to learn it to start using it! SSC-Stat has a tutorial And we also provide 2 demonstrations This way of learning can also give you confidence That you can learn about new software Without always needing a training course After the practical work We discuss the role of SSC-Stat

9. To put your footer here go to View > Header and Footer 9 Practical work It is mainly to learn the software Not statistics If you also learn some statistics, then that is a bonus But dont let it distract you from learning how to use the software Now it is time for the demonstrations and practical work

10. To put your footer here go to View > Header and Footer 10 What is SSC-Stat? A tiny statistics package Designed to support good statistics with Excel Three main menus Manipulate – to organise the data for analysis Visualise - to draw graphs Analyse - to do statistics Dialogues to let you choose which columns to process Statistics packages are column calculators Simple statistics use single columns

11. To put your footer here go to View > Header and Footer 11 SSC-Stat encourages good statistics in Excel What is good statistics with Excel? Keep data to be in list format Use reliable algorithms/calculations So the summary statistics are correct Up to Excel 2003 some simple statistics were not reliable They are, in SSC-Stat Produce good tables – see earlier Produce good, clear graphs – see earlier

12. To put your footer here go to View > Header and Footer 12 Other statistics packages Excel is sufficient as your statistics package for this module But you could also use a statistics package if you wish They are easy to learn Especially if you found SSC-Stat easy to learn Did you – at least so far?
