The software name originally stood for Statistical Package for the Social Sciences (SPSS), reflecting the original market, although the software is now popular in other fields as well, including the health sciences and marketing.

SPSS is a Windows based program that can be used to perform data entry and analysis and to create tables and graphs. SPSS is capable of handling large amounts of data and can perform all of the analyses covered in the text and much more.

The abbreviation SAS stands for Statistical Analysis System. In 1976 the company SAS was founded as the demand for such software increased. Statistical Package for the Social Sciences (SPSS) was developed for the social sciences and was the first statistical programming language for the PC.

How do I update my SPSS license?
Open that folder. In that folder, you will see a program called either SPSS License Authorization Wizard or IBM SPSS Statistics License Authorization Wizard. Right-click the License Authorization Wizard icon, and select Run As Administrator. Log in to a Windows user account with full Administrator access rights.

PSPP–the free, open source version of SPSS. I just heard recently about PSPP, which is a free, open source version of SPSS. ... The most important of these exceptions are, that there are no “time bombs”; your copy of PSPP will not “expire” or deliberately stop working in the future.

Step 1: Click “Data” and then click “Define Variable Properties.” Variables are defined in SPSS with the Data>Define Variable Properties command. Step 2: Click a variable in the left window that you want to define.

#Types of Statistical Tests

Evaluation Designs:

Common Evaluation Designs=>
Most program evaluation plans fall somewhere on the spectrum between a quasi-experimental and non-experimental design. This is often the case because randomization may not be feasible in applied settings.

Similarly, establishing a true experimental design can be costly and time-consuming. The design you select should best fit your evaluation needs and the capacity of your organization.

In the following section you will find illustrations of specific evaluation designs which will help you decide how to structure your data collection efforts. Most of these designs, depending on specifics, would be either quasi-experimental or non-experimental.

There are two commonly used designs in program evaluation: they are the posttest design and the pretest/posttest design. Both these designs can be used with one group or integrate another group as a comparison.

Common Evaluation Designs:

Posttest Only Design:
A posttest only design is simple and straightforward. This type of design can be done with one group (no comparison group) or two groups (with a comparison group) of participants. Participants receive an intervention and are tested afterwards.

One-Group Posttest Only Design in Practice:
A company wants to know whether its employees benefited from a recent employee training conference (listed below as “intervention”). Following the implementation of the training conference, employees were given a short survey (posttest) to assess their satisfaction with the conference. The surveys were used to provide feedback and make changes to next year’s conference.

Two Group Posttest Only Design in Practice:
A posttest is administered to two groups to look at the relationship of abstinence education and positive youth development. One group (comparison group) does not participate in an after school abstinence program. Another group, (program participants), participates in the abstinence education program. Both groups receive a survey that measures positive youth development (posttest). The scores on the posttest are compared to see if the abstinence education program had an impact on positive youth development for those attending the program.
