Although I referred to a quasi-experiment in an earlier post, I do not like the
term. I teach it and try to explain how it is used. However, I also express my
opinion that a study is an experiment or it is not. There are strict
requirements for a true experiment and if they are not all met, the study is
not an experiment. The debate then becomes how much control there is over
extraneous variables so that a judgment about causation can be made.

Many thanks to all for the reassurance. I always tell my students,
"significance" is like being pregnant: one either is pregnant or one is not; it
does not admit of degree. (Although those of you who have borne children might
disagree!)
I also got some new ideas for how I might talk about some of these things with
my students. This is a great listserv.
Thanks again,
