This graph represents the results of the study.
On the basis of the graph, what could you say about the performance of both groups of veterans relative to
the healthy age-matched norms?
O A. On average, participants in the TBI group performed better than the mean of the healthy, age-
matched normative group, but participants in the no-TBI group performed worse than the mean of
the healthy age-matched normative group.
O B. On average, participants in both the TBI group and the no-TBI group performed worse than the
average of the healthy, age-matched normative group.
O C. On average, participants in both the TBI group and the no-TBI group performed better than the
average of the healthy, age-matched normative group.
O D. On average, participants in the TBI group performed worse than the mean of the healthy age-
matched normative group, but participants in the no-TBI group performed better than the mean of
the healthy, age-matched normative group.
