What is an example of a situation in which you would use a t- test for dependent means?
A t-test for dependent means occurs in situations where subjects are measured twice, both
before and after some event. The term "dependent" comes from the means of both the before
and after scores being dependent on each other, because they come from the same subject
population (Aron, Aron, & Coups, 2009). A t-test for dependent means could be used if, for
example, one wanted to study the effects of haptonomy on the mood level of grief counseling
patients. In this case a survey could be given after a normal (clinical) counseling session
centering on the patient's mood. This mean could be compared to a mean mood score from a
survey taken after a counseling session in which haptonomy or haptotherapy was practiced.
For those unfamiliar with the term, haptonomy refers to the science of touch and its practice,
haptotherapy, is becoming more widely used as a therapeutic practice, especially within
Europe. The book, Intimate Death: How the Dying Teach Us How to Live, by Marie de
Hennezel (1998), centers on her work in a hospice unit where she practices haptotherapy to
help ease her patients through the process of dying.
