A note on the figures

The book was designed in color. The ebook is in color, the print edition is black and white, and in both, some figures came out fuzzy. Every figure is on the figures page in full color and at full resolution, including corrected versions of the figures listed below.

Corrections

PageWhereCorrection
106Figure 6-5The magnitude axis reads “<50M,” “$50m–$100m,” and “$150m–$250m,” which leaves a gap between $100M and $150M. The “High” bucket should read “$100M–$250M.” The placement of Risks A, B, and C is unaffected.
112Chapter referenceIn the chapter roadmap, “Chapters 9–13: Collecting, vetting, and blending the data” should read “Chapters 9–14,” since blending is covered in Chapter 14. For the same reason, “the following six chapters” earlier in the paragraph should read “the following seven chapters.”
119Chapter referenceIn “Risk brainstorming workshops, which we’ll cover in Chapter 14,” the reference should be to Chapter 13.
131Figure 8-2“Fines Judgments” should read “Fines & Judgments.”
150Chapter referenceIn “the three-source model that forms the backbone of Chapters 10–12,” the reference should be to Chapters 11–13.
179Range adjustment examplesThe upper bounds in both examples don’t follow the adjustment. Dividing the low end and multiplying the high end by the factor, the ×2 example should read “8–50% annual breach rate” (15% ÷ 2 ≈ 8%, 25% × 2 = 50%), and the ×3 example should read “$100K–$2.1M” ($300K ÷ 3 = $100K, $700K × 3 = $2.1M).
224Chapter referenceIn “You learned the core data quality evaluation framework in Chapter 11,” the reference should be to Chapter 10.
228Chapter referenceIn “the quality adjustment methods from Chapter 11,” the reference should be to Chapter 10.
229Chapter referenceIn “Using the quality adjustment methods from Chapter 11,” the reference should be to Chapter 10.
264Chapter referenceIn “Chapter 15 shows you exactly how to systematically combine them,” the reference should be to Chapter 14.
277Figure 14-3The First Update should read “10%–22% (P50 15%)” to match the text on pages 276–277; the figure shows “10%–20%.”
320Chapter referenceIn “Use the same calibrated ranges (P5, P50, P95) and Monte Carlo simulation from Chapters 9 through 14,” the reference should be to Chapters 4 and 5, where ranges and Monte Carlo simulation are taught.
343Figure 17-1The x-axis title should read “Annual loss ($).” The axis values are in dollars.
