Education in States and Nations: 1991

(ESN) Figure 25: Mathematics proficiency scores for 13-year-olds in countries and public school 8th-grade students in states, by country (1991) and state (1992)

NOTE: The center darkest box indicates a confidence interval around the average mathematics proficiency for the country or state calculated as the mean plus or minus two times the standard error. Test scores range from 0 to 500. The states of Alaska, Illinois, Kansas, Montana, Nevada, Oregon, South Dakota, Vermont, and Washington did not participate in the survey. Caution should be exercised when comparing states and nations by their rank order on any given test measure. These measures are subject to some sampling error. In comparing two estimates, one must use the standard error of the difference (See the note on standard errors of estimates from the IAEP and the NAEP for details.) See Table 25x in the Statistical Appendix for the standard errors.
