The length of fish were measured at 3 different lakes.  Is there evidence to suggest that the average length is not the same at all 3 locations? Lake 1:  3.5, 4.2, 2.1, 3.2, 1.7 Lake 2: 5.1, 6.2, 5.3,4.1 Lake 3: 5.6, 7.1, 6.4, 7.1, 6.4 What is your conclusion? There is not evidence that the mean length at one of the lakes is different then the others. There is evidence hat the mean length at a least one lake is different then the others.
