These plots show a difference in ages for the two periods that can be shown to be statistically significant at the 95 percent level. Summary The Curriculum and Evaluation Standards for School Mathematics emphasizes that many real-world problems available for analysis make statistics an important lens through which students see the applicability of their studies. Problems derived from realworld data, such as almanac information, and problems with the data that students collect, should provide source material for much of their work. This article reports on one student's analysis of data on the academy awards. Analyses similar to this can be used on topics that tie statistics to other academic subjects, such as history, economics, and science, not to mention topics in the students' world of sports, music, and SAT scores.
Many sources are available for answering questions about data.
