This seminar will introduce the basics of using Stata, SPSS and SAS. It is geared to be a one hour introduction covering just the very basics of these packages for those who need to know just a little about each of these packages (e.g., lab support folks).
Overview
 Data Files
 Like an Excel spreadsheet with rows and columns.
 Each row is an observation, each column is a variable and has a variable name.
 Stata data files
 Version 8 and 7 both end in .dta
 Version 8 can read version 7 files, but version 7 cannot read version 8 files
 SPSS data files
 Version 12.x, 11.x, 10.x all end in .sav
 Version 12.x can read older files, but version 11.x probably will have trouble reading version 12.x files.
 SAS data files
 Version 8.x files end in .sas7bdat
 Version 6.x files end in .sd2
 Version 8.x can read version 6.x files, but version 6.x cannot read version 8.x files.
Homework Problem
 Download the High School and Beyond file.
 Save it on your computer.
 Read the High School and Beyond file into Stata/SPSS/SAS.
 Show descriptive statistics for all of the variables.
 Make a histogram of the writing scores.
 Put into a Word document and print it.
Stata
 Download the High School and Beyond File (method 1: click on https://stats.idre.ucla.edu/stat/stata/notes/hs1.dta and save it to your computer)
 Start Stata
 Read the file into Stata
 cd d:temp (or wherever the file is stored)
 use hs1
 Show descriptive statistics for the variables
 summarize
 Copy and paste results into Word
 Choose Courier font to look better

Show histogram for writing score
 histogram write
 Edit – Copy Graph
 Paste into Word. But it pastes in color.
 Prefs – Graph Preferences – Clipboard tab, Color Mapping, grayscale 1
 Method 2 for reading the High School and Beyond file
 use https://stats.idre.ucla.edu/stat/stata/notes/hs1
 save hs1

SPSS
 Download the High School and Beyond File, click on https://stats.idre.ucla.edu/stat/spss/notes/data/hs1.sav and save it to your computer
 Starting SPSS
 Reading the File
 File –>Open (point to location where we stored hs1.sav)
 Show descriptive statistics for the variables
 Analyze > Descriptive Statistics > Descriptives

Copy and paste results into Word
 Edit > Copy, then paste into Word
 Edit > Copy Objects, then paste into Word
 Compare the two results: the first is a table, the second is a picture

Show histogram for writing score
 Graph > Histogram, pick write
 Edit > Copy, then paste into Word

 Download the High School and Beyond File, click on https://stats.idre.ucla.edu/wpcontent/uploads/2016/02/hs1.sas7bdat and save it to your computer
 Starting SAS
 Show descriptive statistics for the variables
 Attempt #1
proc means data="d:temphs1";
run;
Copy and paste results into Word (be careful not to mark below the end of the output)
Need to switch font to use Courier
May need to make page wider
Lines look lousy  Attempt #2 (sometimes necessary depending on versions of software)
OPTIONS FORMCHAR=’—+—+=/<>*’;
proc means data="d:temphs1";
run;
Copy and past results into Word
Use Courier font, page wide enough. Lines look better.
 Attempt #1

Show histogram for writing score

proc univariate data="d:temphs1";
var write;
histogram;
run;  Edit > Copy, then paste into Word (might have to use Paste Special if the graph is in its own window)

proc univariate data="d:temphs1";
 You open a SAS program (*.sas), not a SAS data file

 Within SAS, help probably does not work
