a)
Six elderly women who were hypertensive volunteered to take part in a study
which was designed to determine whether Yoga exercise is effective in
alleviating hypertension. The researcher rated their hypertensiveness on a four-
point
scale
immediately
before
receiving treatment (pre-test), immediately after
treatment has ended (post-test) and three months later (follow-up).

A physical educator believed that the ability to serve well was related to the success or
failure for beginning tennis students. To test this belief the physical educator conducted
a ladder tournament with beginning players to determine the students abilities to win
games against their peers. When the tournament was over, the lecturer ranked the
students according to the order they finished in the tournament. Next, the lecturer
administered a serving test that ranked the students from best to worst on serving skills.
The results of the two sets of rank order scores are shown below.

One characteristic often noted about those in the physical education profession is their
sense of humour. Makato (1992) hypothesized that having a good sense of humour may
be related to good physical health. Suppose that you test this hypothesis by measuring
16 subjects on their sense of humour and their physical health problems. You obtain the
following scores on these two measures.
