Mean affects during high vs. low ILI seasons across six Twitter sets. We only report differences that are statistically significant from the Mann-Whitney U test (p-value ≤ 0.05); To control false positive discovery rate we apply Benjamini-Hochberg correction: * represent Benjamini-Hochberg critical value with a false discovery rate of 0.2; and the rest of points - critical value with a false discovery rate of 0.1.
