III Survival and longitudinal data -- Log rank tests -- Cox regression -- Cox regression with time-dependent variables -- Segmented Cox regression -- Assessing seasonality -- Probability assessment of survival with interval censored data analysis -- Index.;For medical and health workers this book is a must-have, because statistical methods in these fields are vital, and no equivalent work is available. For medical and health students this is equally true. A unique point is its low threshold, textually simple and at the same time full of self-assessment opportunities. Other unique points are the succinctness of the chapters with 3 to 6 pages, the presence of entire-commands-texts of the statistical methodologies reviewed, and the fact that dull scientific texts imposing an unnecessary burden on busy and jaded professionals have been left out. For readers requesting more background, theoretical and mathematical information a note section with references is in each chapter. The first edition in 2010 was the first publication of a complete overview of SPSS methodologies for medical and health statistics. Well over 100,000 copies of various chapters were sold within the first year of publication. Reasons for a rewrite were four. First, many important comments from readers urged for a rewrite. Second, SPSS has produced many updates and upgrades, with relevant novel and improved methodologies. Third, the authors felt that the chapter texts needed some improvements for better readability: chapters have now been classified according the outcome data helpful for choosing your analysis rapidly, a schematic overview of data, and explanatory graphs have been added. Fourth, current data are increasingly complex and many important methods for analysis were missing in the first edition. For that latter purpose some more advanced methods seemed unavoidable, like hierarchical loglinear methods, gamma and Tweedie regressions, and random intercept analyses. In order for the contents of the book to remain covered by the title, the authors renamed the book: SPSS for Starters and 2nd Levelers. Special care was, nonetheless, taken to keep things as simple as possible. Medical and health professionals tend to dislike software syntax. Therefore, virtually no syntax, but, rather, simple menu commands are given. The arithmetic is still of a no-more-than high-school level. Step-by-step analyses of different statistical methodologies are given with the help of 60 SPSS data files available through the internet. Because of the lack of time of this busy group of people, the authors have given every effort to produce a text as succinct as possible.

Part I
Continuous Outcome Data
Springer International Publishing Switzerland 2016
Ton J. Cleophas and Aeilko H. Zwinderman SPSS for Starters and 2nd Levelers 10.1007/978-3-319-20600-4_1
1. One-Sample Continuous Data (One-Sample T-Test, One-Sample Wilcoxon Signed Rank Test, 10 Patients)

General Purpose
Because biological processes are full of variations, statistical tests give no certainties, only chances. Particularly, the chance that a prior hypothesis is true. What hypothesis? Often, a nullhypothesis, which means no difference in your data from a zero effect. A zero effect indicates that a factor, like an intervention or medical treatment does not have any effect. The one sample t-test is adequate for assessment.
Schematic Overview of Type of Data File
Primary Scientific Question Is the mean outcome value significantly different - photo 1
Primary Scientific Question
Is the mean outcome value significantly different from the value zero.
Data Example
The reduction of mean blood pressure after treatment is measured in a sample of patients. We wish to know whether the mean reduction is significantly larger than zero.
  • Outcome
  • outcome=decrease of mean blood pressure after treatment (mm Hg)
Analysis: One-Sample T-Test
The data file is in extras.springer.com, and is entitled chapter1onesamplecontinuous. Open it in SPSS . For analysis the module Compare Means is required. It consists of the following statistical models:
  • Means,
  • One-Sample T-Test ,
  • Independent-Samples T-Test,
  • Paired-Samples T-Test and
  • One Way ANOVA
Command:
  • Analyze....Compare Means ....One-Sample T-Test ....Test Variable(s): enter "mean blood pressure reduction"....click OK.
In the output sheets is the underneath table.

3,2835
It shows that the t-value equals 2,429, which means that with 101=9 degrees of freedom a significant effect is obtained at p=0,038. The reduction of mean blood pressure has an average value of 1,7000 mm Hg, and this average reduction is significantly larger than a reduction of 0,00 mm Hg.
Alternative Analysis: One-Sample Wilcoxon Signed Rank Test
If the data do not follow a Gaussian distribution, this method will be required, but with Gaussian distributions it may be applied even so.
Command:
  • Analyze....Nonparametric tests....One Sample Nonparametric Test s ....click Fields ....Test Fields: enter "mean blood pressure reduction"....click Settings....click Choose Tests....mark Customize Tests....mark Compare median to hypothesized ....Hypothesized median: type "0,00"....click Run.
The underneath table is in the output sheet. The median of the mean blood pressure reductions is significantly different from zero. The treatment is, obviously, successful. The p-value is very similar to that of the above one sample t-test .
Hypotheses test summary
Asymptotic significances are displayed The significance level is 05 - photo 2
Asymptotic significances are displayed. The significance level is ,05
Conclusion
The significant effects indicate that the nullhypothesis of no effect can be rejected. The treatment performs better than no treatment. It may be prudent to use non-parametric test s , if normality is doubtful or can not be proven like with small data as those in the current example.
Note
The theories of null hypotheses and frequency distributions are reviewed in Statistics applied to clinical studies 5th edition, Chaps. 1 and 2, entitled Hypotheses data stratification and The analysis of efficacy data, Springer Heidelberg Germany, 2012, from the same authors.

General Purpose
Studies where two outcomes in one patient are compared with one another are often called crossover studies, and the observations are called paired observations.
As paired observations are usually more similar than unpaired observations, special tests are required in order to adjust for a positive correlation between the paired observations.
