Example#1: A researcher wishes to examine whether time of day (morning versus afternoon)
affects the memory of older and younger participants. He obtains a sample of 40 older individuals
and 40 younger individuals and gives them a passage to read. They are later given a test over the
passage (scores on the test could range from O to 30). HaJf of the individuals are randomly
assigned to read the passage and take the test in the morning, and the other half do so in the
afternoon. The data are reported in the table below (the numbers represent mean test scores for
each group;
that is, "M" is mean).
