Can we explore public opinion on various issues? Can we draw conclusions about the prevailing opinion in the population based solely on the data provided by a "sample" of a few individuals? Can we accurately record the responses of 1,000 individuals without errors? Can we estimate complex behaviors and opinions of millions of citizens based on a "sample"?
This book introduces us to the methodological characteristics of public opinion research. It describes the basic methods of data collection, the construction of the questionnaire, and the selection of the sample as a multi-step process.
However, each step is accompanied by the possibility of some error. Thus, every research is a continuous exercise, with its overall quality judged by the extent to which the researchers responsible for conducting it limit its errors.
Researches are useful, provided that we are careful and precise in interpreting their results. The goal of the book is to answer frequently asked questions, demonstrate the possibilities, and highlight the limitations of public opinion research.
