Chapter 12

Factorial Analysis of Variance

Page 223 - Table 12.2 - Typo in group size notation for Group 12 (Hate South Park and Watched it).  n11 appears instead of n12. (printable pdf file of corrected Table)

Page 225 - Table 12.3 - Has same problem as table 12.2. n12 appears as n11.

Page 226 - Formulas at bottom of page - Two of the ΣX2.jk are mislabeled.

ΣX2.21 is labeled ΣX2.11

ΣX2.22 is labeled ΣX2.21

Correct formulas should appear as follows:

For this example:
ΣX.11 = 10 + 9 + 8 + 6 + 4 = 37
ΣX2.11 = 102 + 92 + 82 + 62 + 42 = 100 + 81 + 64 + 36 + 16 = 297
ΣX.21 = 6 + 5 + 3 + 3 + 2 = 19
ΣX2.21 = 62 + 52 + 32 + 32 + 22 = 36 + 25 + 9 + 9 + 4 = 83
ΣX.12 = 1 + 1 + 0 + 0 + 0 = 2
ΣX2.12 = 12 + 12 + 02 + 02 + 02 = 1 + 1 + 0 + 0 + 0 = 2
ΣX.22 = 2 + 2 + 1 + 0 + 0 = 5
ΣX2.22 = 22 + 22 + 12 + 02 + 02 = 4 + 4 + 1 + 0 + 0 = 9

Page 229 - Step 6 - Summation Symbols are missing from most of the formula. It should appear as follows:

Step 6: Find ΣX2ijk
ΣX2ijk = (ΣX2.11 + ΣX2.21 + ... ΣX2ijk) or (ΣX2.1. + ΣX2.2. + ... ΣX2.j.) or (ΣX2..1 + ΣX2..2 + ... ΣX2..k)

Page 240 & 242 - Table 12.7 & 12.8: Typo in group size notation for Group 12 (Picture Primes and Neutral Food as Fashion Accessory Attitudes).  n11 appears instead of n12. (printable pdf of corrected table)

Page 245 - Step 10 - Wrong formula is presented. It should appear as follows

Similarly, in the example formula for Step 10, there is a mistake in the formula. An extra Σ is included in the formula. It should appear as follows:

Page 245 - Step 11 - There is a 12 hanging out in space bellow the first formula. The 12 is not part of the formula, and should not be there at all.

Page 253-255 - Practice Exercise 5 and 6 - These are really one question. For some reason the two paragraphs making up this exercise each got numbered as their own problem.  Similarly Exercises 7 and 8 make up a single question.
