11Lets 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.
6) - 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
12Editing the Raw Data
- Variable View
- Tab (located lower left hand corner)
- Pages 8 9 of your handout
13Retrieving an Edited Data
- Save the data set to your desktop.
- Call it edited data your initials
- E.g., editeddataRR
- Now we are going to open up a new data set.
- File gt open gt Data
- Navigate to your desktop
- Open up the data file that you downloaded from
our website.
14Review of Workshop
- We inputted raw data (from the survey) into the
data editor - We edited a raw data file in variable view
- pp. 8 - 9
- We retrieved an edited file and perform some
basic statistical analyses.
15Transforming Variable (p 10)
- Recode
- Data may be need to be recoded for a variety of
reasons - Examples
- common for reversing the scales
- Converting a continuous variable into discrete
ordinal variable - Transform gt Recode gt Into Different Variables
- Computing a New Variable
- Can create new variables that may be a function
of pre-existing variables - Transform gt Compute
