Characteristics of the low response:
The graph has major flaws that significantly impede comparisons of the two kinds of bears — for example, incorrectly plotted data, mislabeled axes, or inadequate distinction between the two types of bears.
The description of the data focuses on individual values rather than capturing features of the whole data set.
Either the wrong kind of bear is identified as the heavier one, or no reference is made to the graph at all in support of the conclusion. No attempt is made to consider the ''typical" bear of either type; for example, two specific bears are chosen and the difference of their weights reported.
