Can be used for:
o Processing Questionnaires
o Reporting in Tables and Graphs
o Analyzing: Means, Chi-square, Regression, …and much
more..
3. History
SPSS has a long heritage
Introduced in 1968.
Was originally developed to facilitate statistical
analysis in the social sciences.
Early versions designed to run on mainframe
computers.
On July 28, 2009 IBM announced it was acquiring
SPSS Inc. for $ 1.2 billion in cash
The current versions (2015) are officially named

7. Basic Operations in SPSS
(Basic Steps In Data Analysis)

8. Variables
A concept which can take on different
quantitative values is called a variable.
Ex. What are variables you would consider in buying
a second hand bike?
Brand
Type
Age
Condition (Excellent, good, poor)
Price

9. Dichotomous variables (having two values only)
Yes or No
Male or Female
Income, age or a test score are the examples of
continuous variables.
These variables may take on any value within a given
range, or in some cases, an infinite set.

11. Measurement Scales
The process of assigning numbers to objects in such
a way that specific properties of the objects are
faithfully represented by specific properties of the
numbers.
Types of Scales:
Nominal
Ordinal
Scale
Interval
Ratio
11
12. Types of Scales
Nominal
example: nationality, race, gender…
based on a concept (two categories variable called
“dichotomous nominal”)
Ordinal
example: knowledge, skill... (more than, equal, less than)
rank-ordered in terms of a criterion from highest to lowest
Interval/Ratio
example: age, income, speed...
based on arithmetic qualities and have a fixed zero point

15. Choice of Scales in SPSS
The default is Scale, which refers to an
interval or ratio level of measurement.
Choose Nominal for categorical data,
Ordinal if your data involve rankings, or
ordered values.

23. Manually Entering Data
SPSS makes it easy.
Start with the Data Editor.
There are two tabs at the bottom:
Data View
Variable View
Gives you two ways to enter data:
Start with Data View and just start typing!
Start with Variable View and define your variables
first.
Think of variables as labels that describe your data.
