Throughout the SPSS Survival Manual you will see examples of research that is taken from a number of different data files, survey.zip, error.zip, experim.zip, depress.zip, sleep.zip and staffsurvey.zip. To use these files, which are available here, you will need to download them to your hard drive or memory stick. Once downloaded you'll need to unzip the files. To do this, right click on the downloaded zip file and select 'extract all' from the menu. You can then open them within SPSS.

This is a manufactured data set that was created to provide suitable data for the demonstration of statistical techniques such as t-test for repeated measures, and one-way ANOVA for repeated measures. This data set refers to a fictitious study that involves testing the impact of two different types of interventions in helping students cope with their anxiety concerning a forthcoming statistics course. Students were divided into two equal groups and asked to complete a number of scales (Time 1). These included a Fear of Statistics test, Confidence in Coping with Statistics scale and Depression scale. One group (Group 1) was given a number of sessions designed to improve mathematical skills, the second group (Group 2) was subjected to a program designed to build confidence in the ability to cope with statistics. After the program (Time 2) they were again asked to complete the same scales that they completed before the program. They were also followed up three months later (Time 3). Their performance on a statistics exam was also measured.
This study is a multicentre trial, so stratified block randomisation will be performed in each centre. A randomisation sequence table will be generated by a statician who will not be involved in the trial using Statistical Analysis System (SAS V.9.1). The serial numbers assigned to each patient will be preserved in opaque sealed envelopes. The sealed envelopes will be subsequently given to the trial centre. All patients will not know the surgical regimen until after the surgery. The surgeons will not be blinded to the surgical regimen. Outcome assessors will be blinded to the surgical records in the electronic case report form (eCRF).
Participants must agree to fill in identification registration to enable individual identification of each participant. The monitor will recheck the integrity of this registration. The participant identity registration form will be confidential and will be preserved in the research centre. To ensure confidentiality, duplication of participant identity registration will be not permitted. All reports and letters relating to this study will be tagged with the relevant acronyms and serial number. The participant screening record form will be completed by doctors. The doctors will determine whether participants are eligible for admission to this study.
