03. Teach Yourself Worksheets (2)

Resource type Introduction to Hypothesis Testing (Worksheet)
This teach yourself worksheet provides an overview of the framework used in hypothesis (significance) testing.
Resource type The Sign Test (Worksheet)
The Sign test can be used in place of a paired t-test when your data are either ordinal or the assumption of normality is in doubt. Note however that the Wilcoxon Signed Rank test is often preferred in this case! This teach yourself worksheet provides an introduction to the Sign test including how to do this using SPSS. Note: The "Analyze"--> "Nonparametric Tests"-->"2 Related Samples" step in SPSS (see page 2) has now been changed to Analyze"--> "Nonparametric Tests"-->"LEGACY DIALOGS"-->"2 Related Samples"

04. Tests and Quizzes (4)

Resource type A suite of statistics e-Assessments - Stand-alone resources
DEWIS statistics e-Assessments Learning Modules are concerned with the application of SPSS to the appropriate one sample location test of a data set; t-test, Wilcoxon signed-rank test or Binomial (Sign) test. You may choose examples from a variety of scenarios across a range of disciplines.
Resource type A suite of statistics e-Assessments with supporting materials
These DEWIS Learning Modules are concerned with the application of SPSS to the appropriate one sample location test of a data set; t-test, Wilcoxon signed-rank test or Binomial (Sign) test. You may choose examples from a variety of scenarios across a range of disciplines. The accompanying notes (http://dewisprod.uwe.ac.uk/projects/sigma/PDF/DEWIS_intro.pdf) describe the process of initially exploring your data and then identifying the recommended test. You may choose to complete these modules in the natural order of an analysis, but you may also attempt modules independently in any order if desired. You are not restricted either to only performing the recommended appropriate test, however you will be told at the beginning of a test module whether it is the recommended test or not. You will be given a data set to download which has a reference number. You can log out of DEWIS and return at a later date to complete modules after telling DEWIS the reference number of the data set you wish to be tested on. Each data set is generated randomly and thus you can have multiple attempts at the same scenario with a variety of data sets that will cover the various experiences that you will encounter when analysing data; i.e. data that is appropriate for any one of the three tests and that may or may not have a significant effect. It is recommended that before you use the e-Assessments you download the accompanying notes (http://dewisprod.uwe.ac.uk/projects/sigma/PDF/DEWIS_intro.pdf) and watch this video (http://dewisprod.uwe.ac.uk/projects/sigma/DEWISdemo/DEWISdemo.htm) that demonstrates the use of the learning modules. In particular please note that the e-Assessment marks to the accuracy that SPSS outputs various summary statistics when the data is displayed in the Data View to the recorded accuracy.

08. Staff Resources (1)

Resource type The Statistics Tutor's Quick Guide to Commonly Used Statistical Tests
A handy quick guide to statistical tests and techniques for those providing statistics support. This covers when to use each technique along with the interpretation of results, checking assumptions and what to do if the assumptions are not met. This was developed by the MASH Centre at the University of Sheffield and contributed to the statstutor Community Project by Ellen Marshall (University of Sheffield) and Alun Owen (University of Worcester) and reviewed by Jean Russell and Nick Fieller, (University of Sheffield).
