This dataset example introduces readers to simple regression. This technique allows researchers to evaluate whether a continuous dependent variable is a linear function of a single independent variable. The simple linear regression model is most commonly estimated via ordinary least squares (OLS), and is sometimes called OLS regression. This example describes simple regression, discusses the assumptions underlying it, and shows how to estimate and interpret simple regression models. We illustrate simple regression using a subset of data from the 2005 Eurobarometer: Europeans, Science and Technology (EB63.1). Specifically, we test whether attitudes to science and faith are related to knowledge about science. This is useful if we want to understand the bases of public support for research on science.

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.
