Percentage is higher than U.S. percentage of the same sex at the .05 level of statistical significance.
Percentage is lower than U.S. percentage of the same sex at the .05 level of statistical significance.
*p < .05. Difference in average scores is significant at the .05 level of statistical significance.
1 The physics coverage index is the percentage of the corresponding age cohort covered by students in their final year of secondary school who have taken or are taking physics courses. The corresponding age cohort is determined for education systems individually. In the United States, the corresponding age cohort is considered 18-year-olds. For additional details, see the Technical Notes available at http://nces.ed.gov/timss/timss15technotes.asp.
2 The difference in percentage is calculated by subtracting the females' estimate from the males' estimate using unrounded numbers.
3 Did not satisfy guidelines for sample participation rates.
NOTE: Education systems are ordered by the percentage of the covered population that is female. Standard error is abbreviated as s.e.
