In this chapter, we debate the sources of our analysis and the statistical methods used. We also amply discuss the methodological literature on these subjects. Our data sources are the Arab Opinion Index of the Arab Center for Research and Policy Studies in Doha, Qatar; the Arab Barometer, Wave III; the Pew Spring 2015 Survey; the BBC Global Scan; and the World Values Survey. We debate error margins and other statistical concepts and highlight such methods as factor analysis and econometric time series analysis, available via our used Statistical Program, the SPSS.
