QUEEN MARY, UNIVERSITY OF LONDON MTH 4106 Introduction to Statistics Practical 1 10 January 2012 In this practical you will be introduced to the statistical computing package called Minitab. You will use this package throughout this module, and also in some later modules. It is important that you learn how to use it. Some assignment questions will require use of Minitab. Some test and examination questions may require you to interpret output from Minitab. The work is on the student PC network. I assume that you know how to log onto the PC network and how to print ﬁles from it. 1 (Getting Started) Before you log on, you need to choose the Standard Windows Environment After logging on, choose Public >> Change Course Environment >> Mathematics Department >> Statistics I >> The ﬁrst time that you use Minitab for MTH 4106 Introduction to Statistics you should create a new directory (also called folder ) in your own space and call it STATS . First move to your own space, by clicking on the icon for My Filestore . In File and Folder Tasks , choose Make a new folder A folder icon will appear in the window. Delete its initial name “New Folder” and give it the new name “STATS”. Close the window (click on × in the right top corner of this window). Remember to store all your ﬁles and results from this module in STATS . 2 (Starting Minitab) To start Minitab, Dept >> Minitab-15.1 I Mtb It is good to start your encounter with Minitab through a Minitab Tutorial. For this practical, work through the following tutorial, which is based on one previously supplied with Minitab. Make notes on what you learn from this tutorial. Also, use the empty boxes to write answers to the questions posed during the tutorial. 1

The story Clones are genetically identical cells descended from the same indi- vidual. Researchers have identiﬁed a single poplar clone that yields fast-growing, hardy trees. These trees may one day be an alternative energy resource to con- ventional fuel. Researchers at The Pennsylvania State University planted trees of Poplar Clone 252 on two diﬀerent sites: one site was by a creek, with rich, well-drained soil, and the other site was on a ridge, with dry, sandy soil. They took a sample of three-year-old trees and measured their diameter in centimetres, height in metres, and dry weight of the wood in kilograms. These researchers want to see if they can predict how much a tree weighs from its diameter and height measurements. Congratulations! You have been hired as data analyst for the project, and you will be performing the statistical analysis. In this session you will learn how to: open a worksheet enter and edit data save data compute some basic statistics do arithmetic plot the data edit and add comments to the output print and save your results.
