This dataset is designed for teaching difference of means t-test. The dataset is a subset of data derived from the 2005 Eurobarometer: Europeans, Science and Technology (EB63.1), and the example tests whether knowledge about science varies between men and women. The dataset file is accompanied by a teaching guide, a student guide, and a how-to guide for SPSS.
In this tab you will find guides on using this dataset. The Teaching Guide is designed for faculty who are teaching research methods and statistics, with suggestions on how to use the dataset in lab exercises, in homework assignments and as exam questions. The Student Guide introduces the method for students, and can be used in teaching to provide students with an introductory overview of the method or test. The How-to Guide shows how to perform the technique or test using data analysis software.

Eurobarometer 63.1 (Jan-Feb 2005): Science and Technology, Social Values, and Services of General Interest
European Commission, Brussels; DG Communication Public Opinion Analysis Sector
All respondents were residents in the respective country and aged 15 and over.
A multi-stage, random (probability) sampling design was used for this Eurobarometer. In the first stage, primary sampling units (PSU) were selected from each of the administrative regionals units in every country (Statistical Office of the European Community, EUROSTAT NUTS 2 or equivalent). PSU selection was systematic with probability proportional to population size, from sampling frames stratified by the degree of urbanization. In the next stage, a cluster of starting addresses was selected from each sampled PSU, at random. Further addresses were chosen systematically using standard random route procedures as every Nth address from the initial address. In each household, a respondent was drawn, at random, following the closest birthday rule. No more than one interview was conducted in each household. They were supposed to have sufficient command of one of the respective national language(s) to answer the questionnaire.
Separate samples were drawn for Northern Ireland and East Germany.
