Errata

Pp. 48-57 Box 4.1 Egg shell example
The values for egg shell thickness are an order of magnitude too high. So, for example, a thickness quoted as 3mm should be 0.3mm. Labels along the horizontal axis in Fig. 4-3, 4-4, 4-5 (difference between samples) should also be reduced by an order of magnitude and should actually be 0.02, 0.04, 0.06 etc.

Pp. 87 Figure 6.2
"Factor X" in the upper-right box should be "Factor Q".

Pp. 91 Figure 6.5
The numbers along the vertical axis should be (0.0, 0.2, 0.4, 0.6, 0.8, 1.0) instead of (0.0, 1.2, 1.4, 1.6, 1.8,1.0).

Pp. 106 7.3 section title
The title should be "Factors with more than two levels", rather than "Factors with more than one level".

Pp. 116 Figure 8.2 legend, lines 6-7 (the explanation of standard error in the parentheses)
A clearer version of this explanation is as follows:
What is different between the sexes is the standard error. The standard error is a measure of the precision of a sample mean in estimating the population mean. It increases with increase in within-sample variation and decreases with sample size. For both parasitized and un-parasitized fish, the standard error is much larger in females than males. The power of a statistical test is reduced when the standard error is larger, so a test might find a significant effect of parasitism status in males but not in females.

Pp. 120 Figure 8.4 legend
"split-plot factor" in line 11 should be "sub-plot factor".

Pp. 121 Section 8.5
There are two numbers in parentheses whose meanings are currently unclear, (43) after "a multiple of 64" in line 13 and (42) after "a multiple of 16" in line 16. These should be 4³ and 4², respectively.

Pp. 122 Figure 8.5, second 4x4 square from the right
The letter in the cell at the intersection of the 3rd row and 2nd column should be "A" not "B".

Pp. 131 Box 9.1, lines 1-3
Clearer wording would be:
"Overall flies on day 2 seem to sing slightly slower (i.e. with a larger IPI) than flies on day 1, and the flies on day 3 may sing slightly faster than flies on day 1."

Pp. 131 Box 9.1, 2nd paragraph, line 3
The phrase "the variation in 9.1a" should be "variation in 9.2a."

Pp. 150 2nd paragraph lines 6-10
Clearer wording would be:
"This is analogous to the previous design, with the subtle difference that our within-subject factor is not an experimental treatment like the cognitive task in the previous example. Instead, it is the day that we make our measurement. This can create additional complications when it comes to the analysis, since days of the week cannot be applied in a random order in the same way that our cognitive-task treatments could,?"

Pp. 161 the sentence in the last three lines above Box 11.1
The text is incorrect and should be:

"In general, if you are studying a rare phenomenon you will want your test to be as specific as possible to reduce false positives, whist for common phenomena a sensitive test which reduces the level of false negatives will be better."
