3. Data and Data analysis
• DATA is a collection of facts, such as numbers, words, measurements, observations or just descriptions of things.
• A DATA SET is a representation of data, defining a set of variables" that are measured on a set of cases.“
• A VARIABLE is any characteristic of an object that can be represented as a number. The values that the variable
takes will vary when measurements are made on different objects or at different times.
• INFORMATION is collection of data which conveys some meaningful idea is information. It may provide answers
to questions like who, which, when,why, what, and how.
• DATA PROCESSING is Any operation or set of operations performed upon data, whether or not by automatic
means, such as collection, recording, organization, storage,adaptation or alteration to convert it into useful
information.

5. Data Processing
There are 5 steps included in Data processing:
Editing : Editing of data is a process of examining the collected raw data to detect errors and
omission and to correct these when possible.
Coding : Coding refers to process of assigning numerals or other symbols to answers so that
responses can be put into a limited number of categories or classes.
Classification : Data having a common characteristics are placed in one class and in this way the
entire data get divided into a number of groups or classes.
Data Entry : After the data has been properly arranged and coded, it is entered into the software
that performs the eventual cross tabulation.
Validation : The process of thoroughly checking the collected data to ensure optimal quality levels.
Tabulation : Tabulation is the process of summarizing raw data and displaying the same in compact
form for further analysis.
6. Once data is collected, it is processed to convert it into useful information. The data is
processed again and again until the accurate result is achieved. This is called
data processing cycle.
The data processing is very important activity and involves very careful planning.
Usually, data processing activity involves three basic activities.
1. Input
2. Processing
3. Output

7. Introduction to SPSS
SPSS?
SPSS - Statistical Package for Social Sciences
SPSS is a computer program used for survey authoring and
deployment, data mining, text analytics, statistical analysis,
and collaboration and deployment
8. Introduction to SPSS
• SPSS is short for Statistical Package for Social Sciences, and it is used by various kind of researchers for
complex statistical data analysis.
• SPSS is a comprehensive and flexible statistical analysis and data management solution.
• Its is developed by Norman H. Nie and C. Hadlai Hull of IBM Corporation in the year 1968. It is compatible with
Windows, Linux, UNIX & Mac operating systems. SPSS is among the most widely used programs for statistical
analysis in social science.
• It is easy to learn and use and it includes a full range of data. Management system and editing tools.
• It provides in-depth statistical capabilities and it offers complete plotting, reporting and presentation features.
9. Basic steps for Data analysis in SPSS
Getting data into SPSS
Creating new SPSS data files
Opening existing SPSS system files
Importing data from an ASCII file
Importing data from other file formats
DATA EDITOR
The data editor offers a simple and efficient spreadsheet like facility for entering data and
browsing the working data file.
This window displays the content of the data file.
One can create new data files or modify existing ones.
One can have only one data file open at a time.
10. Basic steps for Data analysis in SPSS
This editor provides two views of the data,
DATA VIEW
Displays the actual data values or defined value labels.
VARIABLE VIEW
Displays variable definition information, including defined variable and value labels, data type, etc..,
BASIC STEPS IN DATA ANALYSIS
Get Your Data Into SPSS: We can open a previously saved SPSS data file, read a spreadsheet, database ,or text
data file, or enter directly in the data editor.
Select a Procedure: Select a procedure from the menus to calculate statistics or to create a chart.
Select The Variable For The Analysis: Variables in the data file are displayed in a dialog box for the procedure.
Run The Procedure: Results are displayed in the viewer
14. Enter Variables
SPSS Interface
1. Click Variable View
2. Type variable name
under Name column (AGE).
NOTE: Variable name
can be 64 bytes long,
and the first

17. Import data from Excel
• Select File ----Open -- Data
• Choose Excel as file type
• Select the file you want to import
• Then click Open
SPSS Interface
19. Basic Statistical Analysis
• Descriptive statistics:
1. Find wrong entries
2. Have basic knowledge about the sample and targeted variables in a
Study
3. Summarize data.
24. Conclusion
Data processing is a series of actions or steps performed on
data for the formation of subsequent
useful information.
SPSS is a software package used for the logical batched and
non batched statistical analysis.
SPSS statistical programs provides a plethora of basic
statistical functions, some of which includes frequencies,
cross tabulations and bivariate statistics.
