Question
A sous chef aims to know whether the tenderness of a cooked meat is affected by
the way it was prepared (quick roast or square roast) and presented (sliced or cubes). A loin of muscles was
cut from 6 different carcasses and each of these muscles were cut into two roasts: (1) quick roast (longer in
length and shorter in width), and (2) square roast (same width and length). Six slices and six cubes were
removed from each roast. Both were cooked with the same temperature on the same day in ovens with the
same model. One cube and one slice from each roast was served and to be rated by six panelists for initial
tenderness. The judges then rated all the roast types and serving method and the average score over all 6
judges for each sample was obtained. Below shows the results from jamovi Ⓒ.
