Summary
of day two:
1.
Mohan
Raj Pradhan: Overview of SPSS:
- Loading of SPSS generates two windows:
-
The
data editor (where you input your data
and carry out statistical functions)
-
And
the output window (this is where results of any analysis will appear)
-
The
various functions of data editor and output windows can be achieved by menu bar
and tool bar.
-
Among
the menu bar, one of the important menus is Help system. This is looked under
problems, when something is not working
-
Design
a coding scheme
We gather data through questionnaire. To analyze
data obtained through questionnaire a coding scheme has to be developed.
A coding scheme is a way to associate a particular
data code with a questionnaire response.
Coding schemes are arbitrary. It may be alphabetic
or numeric. However, it is recommended to use numeric coding scheme.
Mr. Samir K. C.
Editor window:
The data editor window can be divided into two
parts: Data view and variable view
In the data view, actual data is entered and in the
variable view, properties of a variable are defined.
One
of the important properties of variable is value label, described under the
heading values. Here name of value and corresponding numeric value defined in
the coding scheme of a variable will be entered.
Modifying data
values:
Data
received from various sources may not always be in the best format for analysis
and reporting.
SPSS
allows to:
- change data by combining several categories
into one category; or
- by
changing the coding scheme for a variable.
You
can choose to assign the new values to the existing variable or to a new
variable.
This action is requested by RECODE
procedure.
Mr. Naveen Shrestha
Described about relationship of data and statistics.
Data
itself is meaningless but whenever it is processed, which is meaningful to
somebody then it becomes information. Statistics helps in processing data in a
meaningful way. He also broadly divided the data into two categories:
Quantitative
and the other qualitative, which may further be divided into nominal and
ordinal for quantitative data and discrete and continuous for qualitative data.
