This dataset is designed for teaching the difference of means t-test. The dataset is a subset of data derived from an experiment in political psychology: the Salience of National Identity and Americans’ Orientations Toward Subgroups carried out as part of the Time-Sharing Experiments for the Social Sciences (TESS) series, in 2013, and the example shows how to test whether having a strong national identity is associated with more or less favourable opinions about welfare recipients. 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.
