tutorial Oct. 24th
Using the PULSE data again,
create a composite variable consisting of the 8 combinations of Gender
(Male vs Female), Smoker (Yes vs No) and Ran in Place vs Did not run in
place. Using this composite variable, perform planned comparisons to answer
the following questions. Note that even though you may be comparing two
means, you should not do an elementary t-test.
Is mean pulse rate at time 1 different for males and females?
Is mean pulse rate at time 1 different for smokers and
non-smokers?
Is mean pulse rate at time 2 for males who ran in place different
from mean pulse rate at time 2 for males who did not run in place?
Is mean pulse rate at time 2 for females who ran in place
different from mean pulse rate at time 2 for females who did not
run in place?
Is mean rise in pulse rate for males who ran in place different
from mean rise in pulse rate for males who did not run in place?
Is mean rise in pulse rate for females who ran in place
different from mean rise in pulse rate for females who did not
run in place?
Is mean rise in pulse rate for non-smokers who ran in place
different from mean rise in pulse rate for smokers who did not
run in place?
Is mean rise in pulse rate for non-smoking females who ran in place
different from mean rise in pulse rate for smoking females who did
not run in place?
For students who ran in place, is mean rise in pulse rate for
smoking males different from mean rise in pulse rate for all females?
For each of these questions, what do you conclude -- in plain,
non-statistical language?
