Printed | Page 79 Right top box with letter, 2nd paragraph |
The 1st sentence of paragraph 2 in the letter box does not match the feasible region outlined on page 85ff. Instead of "We have time to make 400 ducks or 300 fish." it should read "We have time to make 400 ducks and 300 fish." |

Year after year after year, the data shows FISH HIGHER THAN DUCKS in January. The constraints offered by the author are simply wrong. There is NO "surge in duck sales to beat fish sales" |

I'm confused: you have "Competitor Product Releases" and "PodPhone Product Releases" negatively linked at the top of p.146 (and on p.148 as well), yet at the bottom of p.146 you have them positively linked. Am I missing something? |

About page 148 again, shouldn't there's a link between "Consumer Spending" and "Competitor Sales" instead of a link between "Economy" and "Competitor Sales"? |

page 174, where it is stated (right box) that 9% of 90 people is 10, should be 8.1. |

Mathematical Error: 9% of 90 is not 10 (as your book states). 9% of 90 is 8.1. Thank you. |

9% of 90 is not 10, it is 8.1. It should read "which is about 8 people who test positive but do not have it ." |

Why is the P in the formula suddenly lowercase in the denominator? (same for page 219) |

In the first sentence of the answer to question 3: "host" should be "most". |

Page 382 the first paragraph after the email ( and the bold heading ) |
The phrase "relational databases give you the ability to make" should be in parenthesis. Without them, I had to read the sentence a bunch of times in order to descypher what the phrase "is just enormous" is referring to. What is enormous ? Relational databases ? My ability to make ? |

The link is clickable, but it does not point to actual file, rather to the "Head First Data Analysis" home page. This makes it cumbersome to retrieve the file. |

I agree the formula is too long, and that the R / regular expression is much nicer. I think you can still make the point that the formula is too complicated using this version instead: |
