Excel for statistics Module 1, Session 4
Learning Objectives participants should be able to: • Explain how an Excel add-in can provide • the equivalent of a simple statistics package • Explain what a statistics package contains • Use the SSC-Stat add-in • to analyse a single column of data • Distinguish between the use of a package • and learning how to use it • Know how to find instructions to install • an add-in for Excel
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)
So far with Excel • You can organise data • so it is ready for analysis • You can do some statistics • Tables and graphs Sort, Filter, Tables, Charts and more charts
A statistical add-in • Now we add to Excel’s 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
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 3rd party suppliers • They are not part of Excel when it arrives • There are many add-ins for statistics • They enhance Excel’s 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
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
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
Practical work • It is mainly to learn the software • Not statistics • If you also learn some statistics, • then that is a bonus • But don’t let it distract you • from learning how to use the software Now it is time for the demonstrations and practical work
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
What is good statistics with Excel? • SSC-Stat encourages good statistics in Excel • what is that? • 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 • Produce good, clear graphs
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? • And they are easy to use • And they exchange data easily with Excel • If your Excel data are in a list • Which they need to be for SSC-Stat
Learning objectives: Are you now able to • Explain how an Excel add-in can provide • the equivalent of a very simple statistics package • Explain what a statistics package contains • Use the SSC-Stat add-in • to analyse a single column of data • Distinguish between the use of a package • and learning how to use it
