Comment
The "s" is there because there were a number of comparisons and all the ts fell
into a certain range. So "s" is just a plural.
HOWEVER:
With 23 df, the critical value for t is 2.06, two-tailed. So these obtained ts
might not be significant. The one-tailed critical value is 1.71, so an obtained
t of 1.90 would be significant.
But would p be less than .001? I do not think so because lower down ts greater
than 2.56 have p < .017!
And what is the justification for a one-tailed test?
Sincerely,
Stuart

Subject: [tips] crossposting: errata of errata to APA manuscript???
I just spent 2 hours I did NOT have for this project in making the corrections
from the 7 pages' worth of errata that APA has posted.
I think there are still some errors and maybe someone here can explain these to
me before I fire off an another angry email to APA.
The erratum says:
Chapter 2
page 25 - Indent the first paragraph of the example under the heading "Fourth
paragraph: person to contact (mailing address, e-mail)".
But don't they really want us just to the indent the first line of that
example, and not the whole thing?
-------------------------
The erratum says:
Page 47 - Figure 2.1, p. 12 of sample paper, second paragraph, line 9, chnge
the hyphen "-1.90" to a minus sign and cluse up space next to the numeral :1:
(<1.90).
BUT, this is part of a statistical report that reads, "ts(23)<-1.90..." The t
was in italics but not the s. What the heck does ts stand for? It's not listed
in the abberviations anywhere in the manual and I've never heard of it. I
thought they might want student's t statistic to now be recorded that way, but
no, on the abbreviations page it says to abbreviate student's t as just the
letter t. So what is ts all about? I cannot make italics in this email system,
so just a reminder that the t always appears as an italic, but the s does not.
-----------------------------------
The erratum says:
p. 58 - Figure 2.3, p. 4 of sample paper, boldface heading Summary and
variability of the overall effect.
These words are in italics, which I cannot type in this email program. But
shouldn't the italics be removed and regular font used? Is this not a
continuation at the same level of subheadings as the previous ones?
----------------------------------------
The erratum says:
p. 59 - Figure 2.3, p. 6 of sample paper, in the Albarracin reference, delete
"San Diego, CA: Academic Press"; move ...[references continue]" to next line.
But does the doi reference then remain? It seems like it should go to right
where the "San Diego, CA: Academic Press" was removed from. That's not at all
clear.
-----------------------------------
The erratum says:
Page 209 - Section 7.07, in the motion picture template example, capitalize
"origin."
But shouldn't it just be the "O" in "origin" that needs to be capitalized and
not the whole word?
--------------------------------------
The erratum says:
Page 234 - Figure 8.2...lots of changes
They missed on, in Section 8.14, Subsection (b) line 13, delete the hyphen in
"agreement."
---------------------------------------
Ok, those are my potential corrections to their corrections.
Anyone able to explain or confirm my questions?
