Choosing a command will often lead to a second choice from a subsequent menu and this second choice will be shown after the symbol >. In this manual, bold type is used to show the name of the menu command to be chosen. Hopefully, you will all be familiar with using computer menus by now (from packages such as Word or Excel). Th is is much simpler than typing in commands (as we used to do in days gone by).

In either case, we hope you fi nd this guide takes some of the fear out of statistics: computer analysis is a tool like any other, and will take a lot of the hard work out of statistics once you feel you are in charge!įor any queries concerning this document please contact: Tropical Biology AssociationDepartment of ZoologyDowning Street, Cambridge CB2 3EJ United Kingdom Tel: +44 (0) 1223 336619 e-mail: Biology Association 2008ĪcknowledgementThis booklet was adapted for use on the TBA courses with the kind permission of Dr Su Engstrand, University of Highlands & Islands. Or you may prefer to use the guide as a reference manual, looking up specifi c tests as you need them. You may wish to sit down in front of a computer with Minitab running and work your way through the book, plugging examples into the computer as you go.

It does not tell you which test is right for your analysis, or what assumptions should be met before the test is valid. It provides instructions to carry out tests using Minitab v13.32 for Windows and to help you to interpret the output.
A simple guide to minitab is designed to familiarise you with some of the statistical tests available to you on a software programme on the TBA laptops.
