Holden (1991, p. 934) discusses the methods used to rank high school math performance among various countries. She notes, “According to the International Association for the Evaluation of Educational Achievement, Hungary ranks near the top in 8th-grade math achievement. But by the 12th grade, the country falls to the bottom of the list because it enrolls more students than any other country—50%—in advanced math. Hong Kong, in contrast, comes in first, but only 3% of its 12th graders take math.” Explain why answers to Components 3 and 6 would be most useful when interpreting the results of rankings of high school math performance in various countries, and describe how your interpretation of the results would be affected by knowing the answers.
