The following experiment was devised: a group (random) was divided randomly into 2 : Half were give coffee A the others coffee B, all rated it on a 1-5 Likert scale. Results where analyzed using unpaired Student T test.
This was actually given in a test' students were asked' which statistic test is to be used and so on. Now something looks odd or flawed to me in this example and i cant really put my finger on it. Is it my presupposition that there is no "objectively good" coffee and so the correct way is to compare the 2 coffee with a paired T-test? also a single answer is surly unreliable or accurate but is there more to it? aure its simplified but is this misleading? how so/
