r (correlation) — on the evidence cards. “Across the 87 divisions, when a division has more of X, does it also have more of Y?” Sign is direction; magnitude is tightness. With n = 87, |r| beyond about 0.21 is statistically significant; 0.3 a real pattern, 0.5 strong, 0.7+ very strong. One point per division — never per person.
d (Cohen’s d) — in the analysis record’s typology. Group mean minus everyone-else mean, divided by the pooled standard deviation: how many typical spreads apart the two groups sit. 0.2 small, 0.5 medium, 0.8 large, above 1.2 very large. Positive d: the group sits higher on that variable.
z (standard score) — on the cluster bars. Value minus provincial mean, divided by the provincial standard deviation. Zero is exactly average; +1 one spread above; −1 one spread below.
None of these numbers says why anyone voted. They describe how divisions co-vary — see the ecological-fallacy note.
