Which is the appropriate test (Z test, single sample, independent samples t or related samples t)
for the following: A researcher is interested in determining whether a new med for appetite
suppression is effective by giving the med to one group that has been matched on weight with
another group that reveives a placebo.
Solution
As the medicine is given to two groups and we want to test whether a new med for appetite
suppression is effective or not. This can be tested only by considering the data of the two
samples and taking their difference.
So, the test has to be a two sample test. So, the possibility of a Z test or a single sample t-test is
nullified. Next, as the two sample data are matched by weight, so the data of the two samples are
no more independent. Hence, the option of independent t-test is also nullified.
So, we are only left with the related sample t-test. And this is also supported by the data. As they
are matched by weight, so they are related to each other. Hence we would go for aa \'related
sample t-test\'..
