A researcher would like to determine whether an over-the-counter
cold medication has an effect on mental alertness. A sample of n =
16 participants is obtained, and each person is given a standard
dose of the medication one hour before being tested in a driving
simulation task. For the general population, scores on the
simulation task...

When we compute an independent-samples t-test, we are
looking to see if there are significant differences between the
means of two independent groups, each measured on a different level
of the independent variable.
True or False
When we compute a paired-samples t-test, we are looking
to see if there are significant differences between the means of
two independent groups, each measured on a different level of the
independent variable.
