Question
Transcribed Image Text:Match the given experimental designs or outcomes with the examples provided.
A physician records the blood pressure of patients before
and after aspirin is ingested, then finds the difference in the
two readings to determine if blood pressure decreases as a
result of aspirin intake.
Patients given a sugar pill to help with falling asleep have
just as much improvement in their sleep habits as the
patients given Ambien.
Students are grouped by gender and then randomly
assigned to one of two treatment groups to study the effects
of caffeine on depression.
A study is conducted in which the patient's anxiety level is
assessed by a third party, then either given an anxiety
medication or identical sugar pill before being assessed a
second time by a third party analyst to see if their anxiety
level decreases significantly.

Transcribed Image Text:Doctors identify "chronic tension-type headaches" as headaches that occur almost daily for at least six months. Researchers want to determine if either
anti-depressant medication or stress treatment exercises help eliminate these types of headaches and compare four treatments in the
experiment: antidepressant alone, placebo alone, antidepressant plus stress management, and placebo plus stress management. 480 subjects diagnosed
with "chronic tension-type headaches" by their doctors were first blocked by gender, then blocked by age, and finally randomly assigned to one of the four
treatment groups.
Four treatment groups are created with various
combinations of anti-depressant vs. placebo and stress
management or not.
480 subjects were equally divided into four groups allowing
for 120 subjects receiving each treatment.
Subjects were blocked to reduce the effects of two identified
confounding variables: gender and age.
Subjects were blocked by gender, then age, but ultimately
randomly assigned to one of four treatment groups.
