That's what I wasn't sure about. So maybe time-series
If you want to approach this using hypothesis testing, what is the null
hypothesis? No shift in preference? No systematic shift in preference? (Given
the strong initial preference, I'm not sure what a "non-systematic shift" would
look like.)
The best statistical technique might be "point and
Don,I'm no stats guru, but I'll throw this out as a way to characterize the bird's behavior with respect to probability:It seems to me that "chance" in this situation would be defined by the bird's normal feeding behavior. So, if you know how often (before your manipulation) it goes to the right fi
I'm sure that this would work if I had more Ss. However, with an N

Thanks David,
I'm sure that this would work if I had more Ss. However, with an N of 1
wouldn't that leave me with 0 degrees of freedom? I'm not sure that's
possible.

Normally I don't like "top posting" (leaving several screensful of
quoted material at the bottom of one's post), but it seems expedient
here.
You've got repeated measures on a binary dependent variable, and what
that suggests to me is that you want to use either a GEE (generalized

Hi Tipsters-
I need some advice on the best statistic to use. I'm doing some work
that's outside of my normal area. I'm collaborating with a colleague in
the Biology department and we're investigating learning in Raptors. In
particular, red-tailed hawks. So far we have preliminary data on only one

Title: A Nonparametric Stats Question
A few students in my experimental class are conducting a study that examines taxonomic and thematic structural organization in preschoolers and college students. The essence of the study is that they are presenting eight objects to ten preschoolers and

Hi everyone:
I have a question for the methodologists out there in TIPSland. I'm going to be
working on a study investigating predictors of success among undergraduate college
students. Essentially, this will be a prospective study in which we will collect data
in a number of different areas
I agree with Bob. My mentors required their students to perform four-way ANOVAs
with repeated measures by hand. Our office area was frequently visited by
students from other areas that would bring computer printouts from their
disseration research for interpretation. I always thought that the p
Just a comment. There are two issues here. One is, do test scores predict
performance for the subset of students admitted? The other is, do test scores predict
which students should be admitted? You don't have further data on the students
screened out, which affects your ability to test the

No matter what statistics you use, it would be important to
consider restriction of range if only certain people are selected

I have been asked by the VP to look at the validity of the screening tests
used by the English and Math Departments. The general idea is to look at the
scores on the two tests and see how well they predict subsequent grades.
Another task would be to compare the grades students get in English 1
I'd appreciate help in understanding the following.
I have an unassuming little pair of independent proportions to
test for significance. The Fisher exact test seems ideal.
I use a handy on-line calculator for the Fisher at:
