Introduction to Graphs and Charts
Choice E is the correct answer. The most efficient way to compute greatest rise is
to locate the steepest upward slope on the chart. Note that the steepest climb is between
1982 and 1983. Therefore, choice E indicates the greatest rise in average
test scores.
11. In which year was the average score approximately 85%?
A. 1978
B. 1979
C. 1980
D. 1981
E. 1982
The correct answer is choice C. According to the graph, the average test score was
approximately 85% in 1980. In such cases, when you must read the graph for a precise
measurement, remember that it may be helpful to use your answer sheet as a
straightedge to more accurately compare points with the grid marks along the side.
12. Approximately what was the highest score achieved statewide on the test?
A. 80%
B. 85%
C. 90%
D. 97%
E. cannot be determined from the information given
The first thing to do when confronted with a graph or chart is to read its title to
understand what the graph is telling you. In this case, the graph is relating information
about average scores. It tells you nothing about the highest score achieved.
Thus, E is the correct answer.
Circle Graphs (Pie Charts)
A circle graph, or pie chart, shows the relationship between the whole circle
(100%) and the various slices that represent portions of that 100%. The larger the
slice, the higher the percentage.
