As Figure 2 shows, satisfaction level differences between the two groups were small. Here, satisfaction
is measured as the total percentage of people who have given one of the three most favourable
evaluations on the smiley scale to each package, in accordance with the stipulations given in the TS.
On the basis of the younger panellists’ evaluations, packages E (carton + foil capsule) and A (plastic
bottle) pass the test. For the older panellists, packages D (plastic capsule), E (carton + foil capsule)
and A (plastic bottle) nearly passed but not quite. On the basis of the evaluation of the older panellists,
no package passed the test.
