This is an ongoing listing of errors in the 6th edition. I will give credit to those who point out errors when I can. When I don't know the name of the person who pointed out the error, I am still grateful even if I can't give credit. The book is not yet out. so there should not be errors. This is really just a filler page.
Because of the way I expect to distribute
this list, I cannot be sure
that subscripts and Greek symbols will come across. Subscripts are
usually shown in
parentheses [as in s(1)], superscripts as s^2, and Greek letters are
spelled out.
| Page | Line | Correction |
| 49 | Last paragraph | Kevin Apple has raised a legitimate objection to calling Fig. 3.12 "bimodal." The easiest thing to do is just to drop the word. |
| 56 | Exercise 3.21 | Barbara Thurston pointed out that the link does not work. It has been moved to http://www.sfaf.org/aidsinfo/statistics . |
| 73 | Ex 4.21 | The answer to part b should be 25.1875, and for both a) and b) remember to trim 10% from each end of the distribution. Thanks to Judy Honaker for pointing this out. |
| 78 | Figure 5.1 | Barbara Thurston pointed out that the Y axis runs from 1 to 5 when it should start at 0. I don't know how I made that error, but it is an error. |
| 100 | Ex5.14 | Barbara Thurston also pointed out that I don't define the variable. ENGG stands for Grade in 9th grade English. I plan to describe this data set on the web, but I haven't gotten there yet. |
| 120 | Exercise 6.5c | The correct answers should be a) 84.6, b) 80.025, and c)62.6625 or 62.625 depending on how many decimals you carry. Michael Masson's students at the Univ. of Victoria pointed this out some of these errors, as did Karen Steinberg and someone else whose name I have lost. So did Barbara Thurston. (If you wonder why Barbara Thurston finds so many errors, she's a licensed actuary, and those people read carefully. She is also my daughter.) |
| 132 | Table 7.1 | Stacey Freedenthal at the University of Denver pointed out that many of the percentages in this table are wrong. For cell(1,1) they should be 18.3%, 83.3%, and 14.2%. For cell(1,2) they should be 81.7%, 76.8%, and 63.7%. Somehow I got cell(2,1) right. For cell(2,2) they should be 87.1%, 23.1%, and 19.2%. |
| 288 | Fig. 12.4 | The figure is correct but the data were drawn from a population with a variance of 50, not a variance of 138.89. |
| 410 | 5th line text | Replace with "the critical value on 42 df is approximately 2.423." Ignore references to 17 and 18 df. Thanks to Derrick Watson of the Univ. of Warwick |
| 569 | Exercise 2-1 | When I said that the grade on an exam might be thought of as interval, I had in mind an exam with a numerical grade. One of Stacey Freedenthal's students at the University of Denver thought (reasonably) that I considered the grade to be A/B/C/D/F. The latter would be an ordinal scale. |
There will be a self-extracting archive of all of the data found in DataAll.zip. Simply click on this link and tell the resulting dialog box where you want to store the download--the desktop is fine. After the file is downloaded, click on the downloaded file and indicate where you want the data files to be stored. Once the data are extracted, you can safely delete the archive file itself.
