The page gives a list of known issues in the third edition of *A Portable Introduction to Data Analysis*, published in July 2004.

The errata are classified as being explanatory notes, simple typos or real mathematical errors.

If you find an error in the book then email m.bulmer@uq.edu.au. The first person to report each error will receive a Freddo Frog. (If it is a mathematical error then you get a filled Freddo!)

A minor revision of the third edition was released in January 2005 which corrected all the errors listed here, except those highlighted in grey.

Page | Type | Description |

iii | Typo | "fully expositions" should be "longer expositions" |

3 | Typo | an age measured in whole years |

5 | Typo | ... so that we can see how our results match up ... |

8 | Typo | "Sharede" in table should be "Shared" |

11 | Typo | trialing a new drug |

15 | Typo | random processes |

21 | Typo | variability in sleep |

24 | Typo | contribution of histograms |

31 | Math | The quartiles are wrong in the weight example. They should be Q_{1} = 51 and Q_{3} = 70. |

47 | Typo | particularly since it squares the deviations |

47 | Typo | "male and female heights have roughly the same amount of variability" |

49 | Typo | "(see Section 9)" |

52 | Typo | "The histogram is a an example of" should be "The histogram is an example of" |

64 | Typo | y values above the y mean |

111 | Typo | "so his work was published" |

120 | Typo | "Here 180 cm is 13 cm above the mean" |

156 | Math | The denominator in the z calculation should be 2.36, not 3.83. The value of z is still correct. |

165 | Note | The 13.291 in the calculation is the sample standard deviation (s) of the 30 weights in Table 1.4. |

178 | Typo | The first row in Table 25.1 should be "High" and the second "Normal". |

186 | Typo | The denominator should be 19, not 18, in the confidence interval calculation. (The margin of error, 5.52, is still correct.) |

188 | Typo | Exercise 1 should compare "dye uptake", not "growth". |

200 | Math | In the formula for se(ln(RR)), the numerators should be b/a and d/c (not
a/b and c/d). This changes the numbers in the example. |

202 | Typo | The model for linear regression should have a capital Y, so Y = β_{0} + β_{1}x + U. |

211, 212 | Typo | The use of "log" on these pages should be replaced by "ln" for consistency. |

213 | Typo | "the assumptions for small samples". |

222 | Typo | The caption for Table 32.3 should have "pulse rate" instead of "hours slept". |

222 | Typo | Second last line: "there will be a lot of these" (not "we"). |

252 | Math | The Interaction MS in Table 35.6 is 0.00384. |

284 | Math | The P-value from t_{19}=1.41 is 0.087, not 0.174, since this is a one-sided test. |
