Typos and Clarifications

Please send me more if you find them. Some have been fixed in subsequent printings.
**Chapter 1**

**
Tom Knapp pointed out that we should have cited a more recent paper by
Levin (***American Statistician*, 1993, *47*, 24-26) that illustrates
the concept of regression toward the mean.
**
Tom Knapp pointed out that on page 12, we say that "we believe that we
are the first to feature it [a pair-link diagram] as an alternative
to a scatter plot". It was actually used by Stanley in his 1964 textbook,
***Measurement
in Today's Schools* (see his Figure 3-11, p. 96).

**Chapter 2**

**
Eric Lundquist and Jay Thomas pointed out that the
Z score formulas have X and Y in the wrong formulas on page 25.**
**Chapter 3**

**
The proper spelling is Cal Ripken Jr. on page 42.**
**
On pages 49-50, we discuss various probabilities of persons who score two
or more standard deviations above the mean. We determined those probabilitys
by computer simulation. The text seems to imply a formula for those
probabilities. If there is such a formula, I do not know it.**

**Chapter 5**

**
The warning on page 85 is wrong. The terms "smaller" and "larger" should be reversed. Thanks to Feifei Ye
for pointing out this very embarassing error.
****Chapter 6**

**
The bottom formula on page 88 has a serious typo. Before the last
term in the denominator, there should be a minus not a plus sign.
So it should read - 2rs(x)s(y) where (x) means subscripted. Thanks
to my colleague Irv Kirsch for alterting me to this.**
**Chapter 8**

**
It might have helped to say that the expected change in means over time
given an autoregressive model and stationarity is exponential.**
**Chapter 10**

**
Jay Thomas pointed out that on page 162, the McNemar
test is missing parentheses around the 21 + 16.**
