1 | Stat1250 Week 2 Practical: Introduction to Excel © Copyright Macquarie University Welcome to STAT1250 Practical classes! These classes complement and extend the concepts you learn in lectures. Make sure to discuss your thoughts with the students in your class and ask questions to clarify your learning. Today you will begin to learn about how to use the computer package Excel. Practical participation is compulsory (it is a Hurdle requirement) and participation will be recorded during your class time. You must attend at least 10 of the 12 practicals or you will receive a fail in the unit. You must attend the practical that you are registered in according to e-student. It is your responsibility to complete the participation quiz during your practical. Each practical class will contain: revision of material covered in lectures and tutorials problem solving using Excel The data files that are used in these practicals will be made available on iLearn in the Data Sets section. When completing the practicals having your lecture notes with you is useful for reminding you of definitions and concepts. Today we will complete: opening a data file and editing data in Excel saving the work you have completed using EXCEL cutting and pasting from Excel to Word Hurdle Quiz 1 If you are not familiar with Excel at all there are many, many sites and YouTube videos that can help you. Type something like 'Excel beginners' in a browser then select from the options available. Recommended textbooks have resources for Excel. For example, recommended text book by Black et al (published by Wiley) has how to videos that you might benefit from watching. The add-in will usually be available on Lab computers already. More information on Analysis Tool Pack in Excel is at in-excel-6a63e598-cd6d-42e3-9317-6b40ba1a66b4 You need Excel with data analysis Tool to successfully complete STAT1250 (see iLearn for how to obtain a free copy for your computer/laptop from MQ). Remember: If you have difficulty with any parts of the Practicals ask your practical demonstrator for help during your class. Week 2 Practical Introduction What will we cover today?
2 | Stat1250 Week 2 Practical: Introduction to Excel © Copyright Macquarie University Practicals can be completed on a lab computer or on your own computer/laptop, but not on tablets such as iPad, and certainly not on your smart phone. After you have logged onto the lab computer, find Excel and open it. Excel should appear with a blank worksheet as in the picture below. Excel stores data in columns labelled A,B,C, ........... and in rows numbered 1,2,3,...... Data are stored in cells that are referenced by their column label and row number. For example, the cell that is located in column C and in row 9 is referred to as cell C9. Opening Excel
3 | Stat1250 Week 2 Practical: Introduction to Excel © Copyright Macquarie University At the top of an Excel spreadsheet are menus including Home - which is generally used to format cells Insert - which is used, for example, to add charts Formulas - which is used to add appropriate formulas to the worksheet and so on. Some of these menus will be used in later Practicals. You are expected to be able to use Excel with data analysis and to be able to do your own analysis and interpret the Excel output that is presented in lectures, in the class tests and in the final examination. Excel most basic use is as a calculator. For example, in cell A1 type =123*456 and then press enter. The "=" specifies that we are using a function in this cell that we want an answer for. Did you get 56088? __________________ Excel can be used to add/subtract/multiply/divide (and many other functions) two or more columns together. Type the data in the image below into the same columns of your spreadsheet. In cell C1 type =SUM(A1:B1) . The SUM(A1:B1) command says add the cells specified (A1 and B1) together. Now we want to use the same function for cells C2 to C10. The easiest way to do this is to click in cell C1. At the bottom right hand corner of the cell you can see a little square. Hover over that square until the Excel curser becomes a thin +, using the left hand mouse button click and hold on the + and drag the curser down to C10. The formula should copy to cells C2 through C10 and give you the remaining row sums. Ask your demonstrator if you have any problems during your class time! You can also watch the pre-recorded Practical Video if you missed your class and submit your solution(s). Now we are going to import some data into Excel. Open an internet browser such as Google Chrome and log into iLearn ( Scroll down to the Data Sets section and you will see the names of the data sets that we will use this semester. Excel data files have the extension . xlsx or . xls . Double click on GAPMinder Data Sets.xlsx to download the file. Using Google Chrome, a link to the data file should appear in the lower left hand side of the browser window. Excel as a calculator Download the data from iLearn The Excel menus
