Good morning TIPSters!
My understanding of the point-biserial correlational procedures is that it is
used when one of the variables is dichotomous (e.g. female vs. male; psych
majors vs. non-psych majors). I have a colleague who had a data set in which
she has a "trichotomous" variable (i.e., "uppe
Several people have asked me tothe suggestions I received. Here they are.
Thanks to all who sent ideas!

Assuming they are at least ordinal, you could code them 1, 2, 3 (or -56, 7, 1006,
if you wanted to). You'll have a restriction of range problem that will tend to
supress the final value you get for the coefficient, and the "pct. of variance
accounted for" interpretation of its square will be of du

Although true that coding is arbitrary with 2 groups, this does
not generalize to 3 groups. Depends on the hypothesized

Steven: Yes, and you'll get the same r value with 1,2,3 as you will with
-6, -5, -4, but not with non-equal spaced numbers (e.g. -56, 7,
etcetera, as Christopher said). But be sure to create the codes so the
results will be easily intuitive. If you hypothesize that income

Wouldn't it be more appropriate to use a Spearman Rho if you are asuming
ordinality in your data?

Does anyone know of a survey that assesses stressful experiences of
college students? I'm looking for something similar to the Holmes and
Rahe scale, but that is focused on college students rather than life in
general. Alternatively, I'm looking for something that assesses how
well students cope

Where I come from, it is almost NEVER more appropriate to use Spearman's rho
becaude it assumes a rectangular underlying distribution, which is almost
never the case. (In practic
I came across the "Student Stress Scale" in a personal adjustment text. The source
says it was adapted from Imel, P.M. & Roth, W.T. (1985). Core Concepts in Health, 4E.
Palo Alto, CA: Mayfield, p. 29. The text I found it in is Duffy, K. & Atwater, E.
(2002). Psychology for Living, 7E. Upper Sad
The Intro Psych text by Coon (9th ed) contains the College Life Stress
Inventory. Credit is givne to Renner & Mackin, 1998 in the Teaching of
Psych reference already provided by Bill Goss.
