An investigator conducts an experiment involving the effects of three levels of a drug on memory. 12 subjects are randomly assigned to one of three conditions (0mg, 15mg, 30mg). A different drug level is administered in each condition. Memory is measured 10 minutes after each subject receives the drug. The following scores are recorded. The higher the score, the better the memory.
0mg Drug
6, 10, 8, 11
15mg Drug:
9, 7, 9, 11
30mg Drug:
13, 15, 14, 19

To test whether memory changes with age, a researcher conducts
an experiment in which there are four groups of six subjects each.
The four groups are listed below. All subjects are in good health
and matched in other important variables such as years of
education, IQ, gender and motivation. Each subject is shown a
series of nonsense syllables (a meaningless combination of three
letters such as DAF or FUM) at a rate of one syllable every 4
seconds. The series...

An experimental psychology professor conducts an experiment to
evaluate the effects of Variable A: Math Ability and Variable B:
Teaching Method on student performance in research methods.
Volunteers for the experiment are divided according to math ability
into weak, average, and strong math ability groups. Half of the
students in each math ability group are randomly assigned to one of
two teaching methods: Method 1 (traditional format) or Method 2
(augmented format, which includes additional problem-solving
sessions each week). At...
