List of potentially confusing mistakes:
  • Page 100, top. "The geometric mean is a unitless..." should have been "The geometric SD is a unitless...."
  • Page 135, line 8 (after figure legend). Replace "inactive ointment" with "antibiotic". After the question mark, add: "This probability includes any increase in the infection rate."
  • Page 158, within figure 17.2. The text "ns. P > 0.05" is totally wrong. Should be   "P < 0.05" 
  • Page 162. In the fourth paragraph, "0.03%" should be "0.3%".
  • Page 187, bottom. FRPR equals  A/(A+C),  not C/(A+C)
  • Page 192. "four times the chance of a Type I error than a type II error..." should have been "four times the chance of a Type II error than a type I error...."
  • Page 246, bottom. "Sample size calculations should not be based on the sample size you expect to see" should have been "Sample size calculations should not be based on the effect size you expect to see."
  • Page 289.  The correct CI for the second line  is 1.67 to 7.77. The next sentence in lines 3 and 4 ("In other words...time.") is wrong and should be ignored.
  • Page 507 (top): "And if the P value is just barely smaller than 0.05, there is a 95% chance... " should have been "And if the P value is just barely smaller than 0.05, there is a 97% chance...."
List of trivial (not confusing) mistakes:
  • Page 40. Middle of page. "survived" should be "were infected"
  • Page 58. Top, first bullet. "by the number of samples to calculate C" should have been "by the number of samples to calculate CI."
  • Page 85 (bottom, paragraph on variance). "0.16" should be replaced by "0.4" (which is the SD)
  • Page 117. Definition of prediction interval should be... "range of values that is 95% likely to contain the next sampled value."
  • Page 151. The bottom four paragraphs are the same as the top four paragraphs, so should be ignored.
  • Page 157. Change heading "When a CI includes the null hypothesis" to "When a 95% CI includes the null hypothesis so P>0.05"
  • Page 158. Change heading "When a CI does not include the null hypothesis" to "When a 95% CI does not include the null hypothesis so P<0.05"
  • Page 161 middle. Change "Figure 17.1" to "This example is discussed in depth in Chapter 30, and Figure 30.2"
  • Page 161, bottom. Change "(not explained in detail in this book)" to "(discussed in Chapter 30)"
  • Page 163, middle. The sentence that begins "The 95% CI includes zero," should continue with "so the data are compatible (with 95% confidence) with the conclusion that tighter glucose control has no effect on survival."
  • Page 164, middle. "thedefinitionofthenull..." a bunch of words run together without spaces
  • Page 165, second paragraph. "drug to increase enzyme"
  • Page 171, middle.   "Chapter 18." should be "Chapter 26"
  • Page 172: Missing word. "so the P value will almost always be less than 0.05."
  • Page 176. In the bottom four paragraphs, the abbreviation "FDR" is used four times, when the abbreviation "FPRP" should be used (the meaning of the two is the same, but everywhere else I use FPRP).
  • Page 177 middle. Change "Yes. Your decision..." to "Yes. If computing the FPRP for a proposed experiment, your decision... 
  • Page 177 bottom. "what is he chance..." should be "what is the chance....""
  • Page 190, bottom. Two extra words. "When is the study..." "useless and misleading helpful"
  • Page 205. Top. "consider three scenarios..." should have been "consider four scenarios...."
  • Page 247: "may too low" should be "may be too low"
  • Page 252: "expect the 90% CI to extend " should be 95%
  • Page 258: "from a Gaussian distribution)" has a dangling parenthesis
  • Page. 271: "apixipan..." should be "apixaban"
  • Page 299, middle: "statistically significant (P 0.05)" should have been "statistically significant (P < 0.05)"
  • Page 310, figure legend: "The other two experiments resulted in more growth in the cross-fertilized plant... " should be "The other two experiments resulted in more growth in the self-fertilized plant... "
  • Page. 334, middle: "extends from about 18%z to ...." extra letter after the percent symbol.
  • Page 341,3rd para, " If you are would"
  • Page 342. Last paragraph. " unlikely to be horizontal"
  • Page 350. Everything from the sentence that begins "A large international group..." in the middle of the page down to the bottom of the page is simply a repeat of what came earlier on that page.
  • Page 359, Table 35.1. The labels "sum of squares" and "Scatter from" are reversed.
  • Page 382, first bullet point. Replace "have diabetes" with "have taken diuretics"
  • Page 398: "X3,5encodeswhetherthethirdpatientismarried(thefirstvariableinTable38.2)" should have been "X3,5 encodes whether the third patient is married (the first variable in Table 38.2)"
  • Page 506, middle: "Focus on the third row of the table..." should have been "Focus on the second row of the table...."
  • Page 506 (middle): "Of the 99% of the potential experiments were .." should have been "Of the 99% of the potential experiments where ...."
