Sharon, one more comment:
I teach Research Methods in Psychology to undergraduates. Over the semester
we cover the concept of reliability and in it I give a rough rule of thumb
that a reliability coefficient of .8 is a minimum threshold for acceptable
reliability in psychology. Later in the semester when I start discussing
effect size and correlational data, they all seem to have gotten the
impression that all correlation coefficients must be .8 or better to be
meaningful. Did your student by any chance take my class? ;-) Anyway, I
wonder if she is making similar error in confusing "minimum" reliability
with significance of a correlation.
