NEW: Logging into ASUAD domain • “Returning” ASU Students will no longer be able to log into the ASU.EDU (Kerberos Realm) domain. • All Students must now log into the ASUAD domain in order to access ASU Resources on the computer • Use pull-down arrow to select ASUAD • If you can’t log into the ASUAD, then you will have to reset your password.

Brief Introduction to Statistics with SPSS Roger Berger Mathematical Sciences & Applied Computing Program Rico Rivera Josh Fox Statistics Laboratory http://www.west.asu.edu/StatLab
Workshop Overview • Workshop Objectives (p 1) • Understand Basic Organization of SPSS • How to input, save & retrieve raw data • How raw data file is edited in variable view • Perform basic data analyses • Table of Contents (p 2)
Open up your internet Explorer http://www.west.asu.edu/StatLab • Click on the Stat Lab button (located on left side) • Click on Workshops • Click on Data used for Workshops • Click on Res_Stat_Edited.sav • Please save it in your Desktop. • Close the internet brower.
SPSS Accessibility (p. 3) • Network access • Technopolis (basement of library) • Desktop (hard drive) installed • Computer Classrooms • Stat Lab
Accessing the Statistic Laboratory(p. 3) • Location: CLCC 107 • Phone: (602) 543-6117 • Website: http://www.west.asu.edu/StatLab • Operating hours: See website (changes on a weekly basis) • When using the lab, students sign in at the front counter
Support for Statistics (p. 4) • Function of Stat Lab (also pp. 14-16) • The Stat Lab staff assists students with aspects of statistical software. • The Stat Lab is not set up to provide one-on-one tutorial service for students on a regular basis. • However, we have and frequently do answer general statistic questions. • Statistics Tutoring • Learning Enhancement Center • TRiO (SSS) program
Procedures for Data Analysis (p. 6) Data StatPak Output Interpretation • Collect & organize data • Input & edit the data • Transform Variables [will not be covered] • Analyze data or create graphs • State results and interpret
Please fill out the Research & Statistical Attitude Survey(Remove the last page of your handout) • Response • Strongly Disagree • Disagree • Agree • Strongly Agree • Sex • Male • Female • Age • Under 25 • 25 – 40 • Over 40 • Response • Strongly Disagree = 1 • Disagree = 2 • Agree = 3 • Strongly Agree = 4 • Sex • Male = 1 • Female = 2 • Age • Under 25 = 1 • 25 – 40 = 2 • Over 40 = 3 • Having ID column will help you keep track of cases • What do the first 5 questions (items) measure? • What do items 6 through 10 measure?
Let’s Launch SPSS • Menu Bar • Data & Transform are used to manipulate the data in data editor (i.e., spread sheet) • Analyze and Graphs are used to create output • Tabs (bottom left hand corner of data editor, p. 7) • Data View • Columns: Variables (e.g., questions on survey) • Rows: Cases (e.g., survey) • Variable View • How we edit the variables • Give variables their names, labels, etc • Enter you survey into Data View
Editing the Raw Data • Variable View • Tab (located lower left hand corner) • Pages 10 – 11 of your handout
Contingency Table Examplep 153 of your text book • Littering behavior (Geller, Witmer, & Orebaugh, 1976) • Does a message about not littering written on supermarket hand bills reduce littering behavior? • Two Conditions • Control: contained only a listing of daily specials • Message: also contain message “Please don’t litter. Please dispose of this properly.” • Recorded the number of handbills that were found • Trashcans • Shopping carts, floor, & various places • Could not be found and apparently removed from premises
Frequency Distribution of Instructions by Location(N = 1772) • Given the table we are going to re-created it and also calculate the chi-square statistic in SPSS.
In Variable View • 1st, give the variables names • 2nd, give the variable labels
Value Labels • Set the value labels for row variable • Set the value labels for column variable
Enter values for row • Recall that for row: Control=1 Message=2
Enter values for column • Recall that for Column: Trash Can=1 Litter=2 Removed=3
Enter the frequency • Enter the frequency counts
Enter the frequency • Enter the frequency counts
Creating a contingency table and computing a chi-square (χ2)
Creating a contingency table and calculating a χ2 • Click on button called Statistics
After clicking on button called statistics, you get a dialogue box called Crosstabs: Statistics • Choose Chi-square • In Nominal submenu select Phi & Cramér’s V
Thanks for having us Do keep the “Research and Statistics Attitude Survey” you filled out. Please close SPSS & log off your computer. Please turn in the “SPSS Workshop Evaluation” as you leave the room. Have a good day.
