SPSS for starters / Part 2

Description

This small book addresses different kinds of datafiles, as commonly encountered in clinical research, and their data-analysis on SPSS Software. Some 15 years ago serious statistical analyses were conducted by specialist statisticians using ma- frame computers. Nowadays, there is ready access to statistical computing using personal computers or laptops, and this practice has changed boundaries between basic statistical methods that can be conveniently carried out on a pocket calculator and more advanced statistical methods that can only be executed on a computer. Clinical researchers currently perform basic statistics without professional help from a statistician, including t-tests and chi-square tests. With help of user-friendly software the step from such basic tests to more complex tests has become smaller, and more easy to take. It is our experience as masters’ and doctorate class teachers of the European College of Pharmaceutical Medicine (EC Socrates Project Lyon France) that s- dents are eager to master adequate command of statistical software for that purpose. However, doing so, albeit easy, still takes 20–50 steps from logging in to the final result, and all of these steps have to be learned in order for the procedures to be successful Front Matter....Pages i-ix Introduction....Pages 1-2 One-Sample Continuous and Binary Data (t-Test, z-Test) (10 and 55 Patients)....Pages 3-5 Paired Continuous Data (Paired-t, Wilcoxon) (10 Patients)....Pages 7-9 Unpaired Continuous Data (Unpaired t-Tests, Mann–Whitney) (20 Patients)....Pages 11-13 Linear Regression (20 Patients)....Pages 15-19 Repeated Measures ANOVA, Friedman (10 Patients)....Pages 21-23 Mixed Models (20 Patients)....Pages 25-27 One-Way-ANOVA, Kruskall–Wallis (30 Patients)....Pages 29-31 Trend Test for Continuous Data (30 Patients)....Pages 33-34 Unpaired Binary Data (Chi-Square, Crosstabs) (55 Patients)....Pages 35-37 Logistic Regression (55 Patients)....Pages 39-42 Trend Tests for Binary Data (106 Patients)....Pages 43-45 Paired Binary (McNemar Test) (139 General Practitioners)....Pages 47-49 Multiple Paired Binary Data (Cochran’s Q Test) (139 Patients)....Pages 51-53 Cox Regression (60 Patients)....Pages 55-58 Cox Regression with Time-dependent Variables (60 Patients)....Pages 59-61 Validating Qualitative Diagnostic Tests (575 Patients)....Pages 63-66 Validating Quantitative Diagnostic Tests (17 Patients)....Pages 67-68 Reliability Assessment of Qualitative Diagnostic Tests (17 Patients)....Pages 69-70 Reliability Assessment of Quantitative Diagnostic Tests (17 Patients)....Pages 71-72 Final Remarks....Pages 73-73 Back Matter....Pages 75-88
