Figure 1. Graphical Representation of Voters’ Ideological Positioning. Note: Confidence intervals are at the 84% level following Macgregor-Fors and Payton (2013). Confidence intervals of 84% are used in the figure, since a classic 95% confidence interval is computed against a baseline of zero and should not be compared to another mean. For instance, overlapping 95% confidence intervals may not necessarily mean that a different is not significant. Macgregor-Fors and Payton (2013) demonstrate that when comparing two values against each other, an 84% confidence interval is the equivalent of a 95% confidence interval.
