AN INTRODUCTION TO SPSS 1 & ENDNOTE Rachel S. Shi PhD student (ISEM) @ HKBU Oct. 2012 AGENDA Basic SPSS skills Input data Compute Mean & Standard Deviation Plot pie chart & histogram Run a regression model Endnote skills Install free-license version Create new reference (manually & import from Internet) Cite while you write Brief introduction to Qualtrics 2 BASIC SPSS SKILLS SPSS - Statistical Package for the Social Sciences Definition: SPSS is a computer program used for survey authoring and deployment, data mining, text analytics, statistical analysis, and collaboration and deployment. (Wikipedia) 3 BASIC SPSS SKILLS – INPUT DATA Go to Dr.Vincent’s website and download the data file: www.hkbu.edu.hk/~vwschow (Lecture notes – ISEM3120 – Data set 1 & Sample Questionnaire) Input Data Open SPSS (close the excel file first) Open an existing data source – OK Select your data file (in case of excel file, you need to change the “File of type” to Excel (*.xls,*.xlsx,*.xlsm)) Another way to open data: File – Open – Data 4 BASIC SPSS SKILLS – COMPUTE MEAN & STANDARD DEVIATION Mean – the sum of the values divided by the number of values. Example: Compute the Mean of Factor 2 (Q14-Q18) 1. Transform – Compute Variable 2. Give a name for target variable: MN_F2 3. Function group: All 4. Functions and special variables: Mean (double click) 5. We get the formula of Mean in Numeric Expression: MEAN(?,?) 6. Select Q14-Q18 to replace the “?” in the formula, Qs should be separated with a “,” 7. Click OK 8. Then we can see the mean of Factor2 (MN_F2) in the last column of the data file. 5 BASIC SPSS SKILLS – COMPUTE MEAN & STANDARD DEVIATION Standard Deviation – shows how much variation exists from the average (mean value). Example: Compute the Standard Deviation of Factor 2 (Q14-Q18) 1. Transform – Compute Variable 2. Give a name for target variable: SD_F2 3. Function group: All 4. Functions and special variables: Sd (double click) 5. We get the formula of Mean in Numeric Expression: SD(?,?) 6. Select Q14-Q18 to replace the “?” in the formula, Qs should be separated with a “,” 7. Click OK 8. Then we can see the Standard Deviation of Factor2 (SD_F2) in the last column of the data file. 6 BASIC SPSS SKILLS – COMPUTE MEAN & STANDARD DEVIATION Another way to compute Mean & Std. Deviation Analyze – Descriptive Statistics – Frequencies Select the variables you would like to compute, in this case, Q14 – Q18 Click Statistics Check “Mean” and “Std. deviation”, and click Continue Click OK Then you can see the result in the output window 7 BASIC SPSS SKILLS – PLOT PIE CHART & HISTOGRAM Pie chart Graphs – Legacy Dialogues – Pie Select “Summaries of groups of cases”, click Define Drag the variable you want to plot pie chart into “Define slices by” Click OK Then you can see the pie chart in the output window 8 BASIC SPSS SKILLS – PLOT PIE CHART & HISTOGRAM Histogram Graphs – Legacy Dialogues – Histogram Select the variable Check “display normal curve” Click OK Then you can see the histogram in the output window 9 BASIC SPSS SKILLS – RUN A REGRESSION MODEL Y = aX1 + bX2 Y: Dependent variable X1, X2: Independent variable a, b: coefficient 10 BASIC SPSS SKILLS – RUN A REGRESSION MODEL Example: Run a regression modeling with Factor2 (F2), Factor4 (F4) and Overall User Satisfaction (OUS) Compute the Mean value of F2, F4, and OUS : MN_F2, MN_F4, MN_OUS Analyze – Regression – Linear Put MN_OUS into Dependent Put MN_F2 and MN_F4 into Independent Read the result: R2, β, Sig. 11 ENDNOTE SKILLS Endnote is a reference management software package, used to manage bibliographies and references when writing essays and articles. (Wikipedia) Main purpose for BBA project: Manage reference Cite reference 12 ENDNOTE SKILLS - INSTALL Download Endnote at: http://pan.baidu.com/share/link?shareid=80620&uk=2 684802673 Install steps: 1. Double Click file "ENX4Inst.exe" 2. Click Next for all except it ask for product code. Select install Trial Version 3. Let it do the install and click finish when it complete 4. Go to Cracked folder and copy file "EndNote.exe" 5. Open the folder in which you installed your Endnote. (Default folder should be: C:\Program Files\EndNote X4 ) 8. Right click and select "paste" 9. You could use Endnote now 13 ENDNOTE SKILLS - INSTALL Get started with Endnote Create a new library (Can save it on your local disk or on your finger ) A library is where you put a set of references. (e.g., You can create a library only for one paper) To open your library, find the folder where you save your library, then double click “My Endnote Library.enl” Create new group in your library: Right click “My Groups” – “Create Group” 14 ENDNOTE SKILLS – CREATE NEW REFERENCE Manually create reference Reference – New Reference Input the information of a article (i.e., author, year, title, journal … ) Attach a file to a reference Edit reference Double click a reference, or Select a reference – right click – Edit Reference Delete reference Drag the reference to Trash, or Select a reference – right click – Move Reference To Trash 15 ENDNOTE SKILLS – CREATE NEW REFERENCE Import reference from Internet (e.g., Google Scholar) Open Google Scholar – Settings – Search Results – Bibliography manager – Show links to import citations into “Endnote” Example: Search articles about “e-commerce” Find the paper you want Click “Import into Endnote” (Right down corner) Double click the downloaded file (.enw) Then you can see the new reference in Endnote 16 ENDNOTE SKILLS – CITE REFERENCE IN A PAPER Connect Word with Endnote 1. Open the folder where you install Endnote 2. Endnote X4 - Product-Support – CWYW 3. Find the following two files, and copy EndNote Cwyw.dll & EndNote Cwyw.dot 4. Close Endnote and Open Word 5. Office Button – Word Options – Trust Center – Trust Center Settings – Trusted Locations 6. Double click “Word 2007 default location: StartUp” 7. Copy the address “C:\Documents and Settings\...\Word\Startup\” 17 ENDNOTE SKILLS – CITE REFERENCE IN A PAPER Connect Word with Endnote (2) 8. Then close Word 9. Past the address into one address box, then open the folder 9. Past the two files you copied before into this folder 10. Now open Word again, you will see Endnote X4 in the Menu 18 ENDNOTE SKILLS – CITE REFERENCE IN A PAPER Cite While You Write Open your Endnote Library, and then open Word Click “Endnote X4” in the Menu of Word Insert Citation – Find Citation Search the key word of the article you want to cite Select the article, and click Insert 19 ENDNOTE SKILLS – CITE REFERENCE IN A PAPER Select the reference style Select Endnote X4 in Word menu bar Click the small arrow beside Bibliography Then you can choose reference style in the “With output” drop down menu 20 AN BRIEF INTRODUCTION TO QUALTRICS Qualtrics software enables users to do any kind of online data collection and analysis.
